This specification relates generally to the application of machine learning operations to data from disparate sources to optimize agricultural production.
A grower is a farmer or other agricultural producer that plants, grows, and harvests crops, such as grain (e.g., wheat), fibers (e.g., cotton), vegetables, fruits, and so forth. Various geographic, weather-related, agronomic, and environmental factors may affect crop production. Some of these factors are within the control of the grower, whereas others are not. For example, the grower can change planting strategies or affect soil composition, but cannot control the weather. Further, the quantity of information associated with these factors that is readily available to a grower can be so large as to limit the amount of the information a grower can utilize when making planting, growing, and harvesting decisions, even when utilizing existing crop production models. Accordingly, growers are often making decisions that can affect crop production based on an incomplete set of information or an imperfect understanding and analysis of available information.
In one embodiment, a system optimizes crop productivity by accessing crop growth information describing, for each of a plurality of plots of land, 1) characteristics of the plots of land, 2) a type of crop planted on the plot of land, 3) characteristics of farming operations performed for the planted crop, and 4) a corresponding crop productivity. The system normalizes the crop growth information by formatting similar portions of the crop growth information into a unified format and a unified scale and stores the normalized crop growth information in a columnar database. The system trains a crop prediction engine by applying one or more machine learning operations to the stored normalized crop growth information. The crop prediction engine maps, for a particular type of crop, a combination of one or more characteristics of the plot of land and characteristics of farming operations performed for the planted crop to an expected corresponding crop productivity. In response to receiving a request from a grower to optimize crop productivity for a first type of crop and a first portion of land on which the first crop is to be planted, the request identifying a first set of farming operations to be performed by the grower, the system accesses field information describing characteristics of the first portion of land and applies the crop prediction engine to the accessed field information and the first set of farming operations to produce a first expected crop productivity. The system applies the crop prediction engine to the accessed field information to identify a second set of farming operations that can produce a second expected crop productivity and modifies the first set of farming operations based on the second set of farming operations to produce a modified set of farming operations. Responsive to the second expected productivity being greater than the first expected productivity, the system presents, within an interface of a device associated with the grower, the modified set of farming operations. The grower performs the modified set of farming operations for the first type of crop on the first portion of land.
In another embodiment, a system executes a method for crop productivity optimization by accessing, for a first portion of land associated with a user, field information describing characteristics of the first portion of land related to crop growth from a plurality of data sources. The system applies a prediction model to the accessed field information. The prediction model is trained on crop growth information and maps, for sets of land characteristics, one or more farming operations to crop productivities by performing one or more machine learning operations. Based on an output of the prediction model, the system selects a set of farming operations that maximize crop productivity and modifies a user interface displayed by a client device of the user to display a crop growth program based on the selected set of farming operations.

The figures depict various embodiments for purposes of illustration only. One skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles described herein.
The grower client devices 102, broker client devices 104, crop recipient client devices 106, and agronomist client devices 108 are computing devices capable of receiving user input, displaying information to a user, and transmitting and/or receiving data via the network 120. Hereafter, a “client device” can refer to any of the grower client device 102, broker client device 104, crop recipient client device 106, and agronomist client device 108. In one embodiment, a client device may be any device having computer functionality, such as a personal digital assistant (PDA), a mobile telephone, a smartphone, a tablet computer, a desktop or laptop computer, a server, a workstation, smart farming equipment (such as a smart tractor, sprinkler system, and the like), unmanned aerial and ground based vehicles both remotely controlled and autonomous, or another suitable device. A client device is configured to communicate with the crop prediction system 125 via the network 120, for example using a native application executed by the client device, a web browser running on the client device, or through an application programming interface (API) accessed by a native operating system of the client device, such as IOS® or ANDROID™.
The grower client device 102 communicates with the crop prediction system 125 via the network 120 to request and receive crop prediction information, such as predictions of crop production, selections of crops to plant, and farming operations that, when performed, optimize crop productivity. In one embodiment, the grower client device 102 accesses the crop prediction system 125 via an interface 130 generated by the crop prediction system 125. In some embodiments, the grower client device 102 receives user input from a grower describing geographic and agricultural data associated with one or more portions of land farmed by a user of the grower client device, for instance in conjunction with a request for crop prediction information. The geographic and agricultural data from the grower client device 102 can be used by the crop prediction system 125, for instance to train one or more crop prediction models and/or as an input to previously trained crop prediction models in order to predict crop production and identify a set of farming operations that can optimize crop production.
As used herein, a “crop prediction model” (or “machine learning prediction model”, or simply “prediction model” hereinafter) refers to any model that uses one or more machine learning operations to predict a measure of crop production based on information comprising field information, or that is trained on information comprising field information using one or more machine learning operations. In application, crop prediction models produce crop prediction information, including a predicted measure of crop production and a set of farming operations that, when performed, is expected to produce the predicted measure of crop production. In practice, a crop prediction model can use or be trained by any machine learning operation, such as those described herein, or any combination of machine learning operations for predictions of crop production. As used herein, “crop prediction information” (or “crop production prediction information”, “prediction crop production”, or simply “prediction information” hereinafter) can refer to any measure of an expected crop production, such as crop yield, crop quality, crop value, or any other suitable measure of crop production (including those described herein), and can refer to a set of farming operations expected to result in the measure of expected crop production when performed in a specified manner, at a specified time/location, and the like. Likewise, as used herein, “field information” can include one or more of past and present crop production information, past and present geographic information, past and present agricultural information, past and present agronomic information, past and present sensor data associated with crop production, any other information related to the planting, growing, and harvesting of a crop, and any other field parameters as described herein.
As used herein, “crop quality” can refer to any aspect of a crop that adds value to a grower, broker, or crop recipient. In some embodiments, crop quality refers to a physical or chemical attribute of a crop, for instance one or more of: a genetic trait, modification, or edit (or lack thereof); an epigenetic signature or lack thereof; a crop content (e.g., moisture, protein, carbohydrate, ash, fiber, fat, oil); a crop color, whiteness, weight, transparency, hardness, percent chalky grains, proportion of corneous endosperm, presence of foreign matter, absorption of water, milling degree, kernel size distribution or volume, average grain length or breadth, density, or length/breadth ratio; a number or percentage of broken kernels or kernels with stress cracks; a falling number; a farinograph; a number or percentage of immature grains; a measure of wet gluten; a sodium dodecyl sulfate sedimentation; toxin levels (for example, mycotoxin levels, including vomitoxin, fumonisin, ochratoxin, or aflatoxin levels); damage levels (for example, mold, insect, heat, cold, frost or other material damage); and the like. In some embodiments, crop quality refers to an attribute of a production method or environment, for instance one or more of: a soil type, chemistry, or structure; a climate type, weather type, or magnitude or frequency of weather events; a soil or air temperature or moisture; a number of degree days; a rain quantity; an irrigation type or lack thereof; a tillage frequency; a cover crop (past and present); a crop rotation; whether the crop is organic, shade grown, greenhouse grown, fair-wage grown, no-till, pollution-free, or carbon neutral; levels and types of fertilizer, chemical, herbicide, or pesticide use or lack thereof; a geography of production (for example, country of origin, American Viticultural Area, mountain grown); and the like.
In some embodiments, crop quality is affected by, or may be inferred from, the timing of one or more production practice. For example, the food grade quality may be inferred from the variety of plant, damage levels, and one or more production practices used to grow the plant. In another example, one or more qualities may be inferred from the maturity or growth stage of a crop. In some embodiments, quality is an attribute of a method of storing a harvested crop (e.g., the type of storage: bin, bag, pile, in-field, box, tank, other containerization), the environmental conditions (e.g. temperature, light, moisture/relative humidity, presence of pests, CO2 levels) to which the good encountered during storage, method of preserving the good (e.g. freezing, drying, chemically treating), or a function of the length of time of storage. In some embodiments, quality is a calculated, derived, inferred, or subjective classification based on one or more measured or observed physical or chemical attributes of a crop, or a farming operation used in its production. In some embodiments, a quality metric is a grading or certification by an organization or agency, for example grading by the USDA, organic certification, or non-GMO certification. In some embodiments, a quality metric is inferred from one or more measurements made of crops during the growing season, for example wheat grain protein content may be inferred from measurement of crop canopies using hyperspectral sensors and or NIR or visible spectroscopy of whole wheat grains. In some embodiments, one or more quality metric is collected, measured or observed during harvest, for example dry matter content of corn may be measured using near-infrared spectroscopy on a combine.
The broker client device 104 communicates with the crop prediction system 125 via the network 120 to receive information about crop production for one or more portions of land, and to send requests for harvested crops (for instance, to the grower client device 102). In this example, the user of the broker client device 104 is in communication with a grower and enters into an agreement to obtain from the grower some or all of a harvested crop. Thus, the user of the broker client device may be a crop recipient. In one embodiment, the broker client device 104 accesses the crop prediction system 125 via an interface 130 generated by the crop prediction system 125 that allows the user of the broker client device 104 to identify predicted crop production information from one or more growers, to identify sets of farming operations to suggest or provide to the one or more growers in order to optimize crop production, to identify one or more prospective crop recipients in addition to the crop broker, and to automate the generation of crop acquisition agreements with the one or more prospective crop recipients. A crop recipient may receive a harvested crop from a grower or from a crop broker.
The crop recipient client device 106 communicates with the crop prediction system 125 via the network 120 to receive information about predicted crop production of one or more growers. For instance, a user of the crop recipient client device 106 can identify expected crop productions of one or more growers, including a type of crop produced by a grower, an expected quantity of the crop produced by a grower, and a comparison of alternative crop types and total crop quantities across a set of growers (such as all growers in a geographic region). A user of the crop recipient client device 106 can use this information to enter into crop acquisition agreements with one or more growers or one or more brokers (via one or more broker client devices 104).
The agronomist client device 108 communicates with the crop prediction system 125 via the network 120 to access crop prediction information generated by the crop prediction system. In one embodiment, a user of the agronomist client device 108 (such as an agricultural specialist, an individual scouting or observing a planted crop, etc.) can review the crop prediction information, including a set of farming operations identified by the crop prediction system 125 to optimize a predicted crop production, and can modify the identified set of farming operations. For example, a user of the agronomist client device 108 may access prediction information and a corresponding set of farming operations identified by the crop prediction system 125 that includes the application of a particular type of fertilizer and a harvest date. The user of the agronomist client device 108 can change the type of fertilizer to be applied, for instance based on the type of fertilizer being unavailable to a particular grower, and can change the harvest date, for instance by moving the harvest date up based on expected inclement weather. In other words, a user of the agronomist client device 108 can modify farming operations identified by the crop prediction system 125 as optimal based on information available to the user but not available to the crop prediction system 125 at the time the predictions were made. Likewise, an agronomist can modify field information on which the crop prediction system 125 is applied (such as a field location, a crop type, an expected rainfall, and the like), and can request that the crop prediction information generated by the crop prediction system be re-generated in order to observe the effect of the modified field information on the crop prediction information. It should be noted that in some embodiments, the agronomist client device 108 and the broker client device 104 can be the same device, and the broker and agronomist can be the same entity.
The external databases 112 are one or more sources of data describing past or present actions, events, and characteristics associated with crop production that can be used by machine learning processes of the crop prediction system 125 to train crop prediction models, to apply crop prediction models to predict future crop production, and to identify farming operations that optimize future crop production. Each external database 112 may be connected to, or accessible over, one or more wireless computer networks, such as a WiFi, an LTE network, an ad hoc network (e.g., a mesh network), personal area networks (e.g., Bluetooth, near field communication, etc.), and the like. External databases 112 may include one or more Web-based servers which may provide access to stored and/or real time information. In some embodiments, the crop prediction system 125 accesses information from the external databases 112 directly, while in other embodiments, the information is manually entered (for instance, by a grower, an agronomist, or an entity associated with the crop prediction system (for instance, via a GUI generated by the interface module 130 and displayed via the grower client device 102, the agronomist client device 108, or the like). Examples of external databases 112 can include:
The sensor data sources 114 are one or more sources of data taken from sensors describing past or current measurements associated with crop production that can be used by machine learning processes of the crop prediction system 125 to train crop prediction models, to apply crop prediction models to predict future crop production, and to identify farming operations that optimize future crop production. In some embodiments, sensor data sources are one or more sources of data taken from sensors describing past or current measurements associated with crop growth, the environment and/or portions of land. In one embodiment, each sensor data source 114 may be connected to, or accessible over, one or more wireless computer networks, such as a WiFi, an LTE network, an ad hoc network (e.g., a mesh network), personal area networks (e.g., Bluetooth, near field communication, etc.), and the like. In such embodiments, the crop prediction system 125 may directly couple with one or more sensor data sources 114 and can receive sensor data without human intervention. For instance, a smart tractor can collect information such as temperature and sunlight information while operating within a field, and can communicatively couple with the crop prediction system 125 (for instance, via an LTE network) to provide the collected temperature and sunlight information in association with information identifying the field. In other embodiments, data from sensor data sources 114 may be manually entered (e.g., by growers or agronomists) within a data entry GUI generated by the interface module 130 and presented by a client device.
Sensor data from sensor data sources 114 may be taken at one or more times during a growing season or across multiple growing seasons, at manual or automated triggers (e.g., a threshold time since a previous measurement; a request by a grower to receive a measurement). Sensor data sources 114 may be deployed across diverse locations (e.g., spatially along the surface of a field, at different depths or elevations relative to the ground) and at different times during the growing season. Sensor data sources 114 may additionally be located at fixed points (e.g., a sensor placed at a designated point on a field) or may be coupled to moving objects (e.g., an autonomous, manned, or remotely controlled land or aerial vehicle). In addition to sensor measurements, sensor health data (such as available power, component malfunction or degradation, diminished communication strength, etc.) and other sensor metadata (such as GPS location data) can be collected for use in verifying the quality of measurement data collected by the sensors and determining the health of the sensors themselves. Examples of sensor data sources 114 can include:
The image data sources 116 are one or more sources of image data that can be used by machine learning operation of the crop prediction system 125 to train crop prediction models, to apply crop prediction models to predict future crop production, and to identify farming operations that optimize future crop production. In one embodiment, each image data source 116 may be connected to, or accessible over, one or more wireless computer networks, such as a WiFi, an LTE network, an ad hoc network (e.g., a mesh network), personal area networks (e.g., Bluetooth, near field communication, etc.), and the like. In such embodiments, the crop prediction system 125 may directly couple with one or more image data sources 116 and can receive image data without human intervention. For instance, a drone can collect images during operation and can communicatively couple with the crop prediction system 125 (for instance, via an LTE network) to provide the collected images in association with information identifying the field. As used herein, “image data source” can refer individually to the instrument capturing the image (such as the camera, radiometer, and the like) and collectively to the instrument capturing the image and any infrastructure (such as a vehicle, stand, machinery, and the like) to which the instrument is coupled. As used herein, “image data” can refer to viewable image files (for instance, in the JPG or .PNG format), to reflectance and absorbance data at one or more spectral bands including a continuous range of spectra (e.g. hyperspectral images), to light data in both the visible (e.g. light between about 375 nm and 725 nm in wavelength) and non-visible spectrum (e.g. light within the infrared “IR” or ultraviolet “UV” spectrums) and combinations of visible and non-visible spectrum, or to any representation of light signals. In various embodiments, image data sources 116 can include:
The crop prediction system 125 receives data from the external databases 112, sensor data sources 114, and image data sources 116, and performs machine learning operations on the received data to produce one or more crop prediction models. The data from these data sources can be combined, and a standard feature set can be extracted from the combined data, enabling crop prediction models to be generated across different temporal systems, different spatial coordinate systems, and measurement systems. For example, sensor data streams can be a time series of scalar values linked to a specific latitude/longitude coordinate. Likewise, LiDAR data can be an array of scalar elevation values on a 10 m rectangular coordinate system, and satellite imagery can be spatial aggregates of bands of wavelengths within specific geographic boundaries. After aggregating and standardizing data from these data streams (for instance to a universal coordinate system, such as a Military Grid Reference System), feature sets can be extracted and combined (such as a soil wetness index from raw elevation data, or cumulative growing degree days from crop types and planting dates).
One or more machine learning operations can be performed on the calculated feature sets to produce the one or more crop prediction models. The crop prediction models can then be applied to data describing a portion of land in order to predict a crop production for the portion of land. The crop prediction system 125 is configured to communicate with the network 120 and may be accessed by client devices via the network such as grower client devices 102, broker devices 104, crop recipient client devices 106, and agronomist devices 108. The crop prediction system shown in
The interface 130 coordinates communications for the crop prediction system 125 within the environment 100, communicatively coupling to, transmitting data to, and receiving data from the other components of
The geographic database 135 stores and maintains data describing geographic characteristics of portions of land (such as fields, plots, sub-portions of the same, and the like) that may impact crop production. As used herein, a “portion of land” refers to any amount of land in any shape or size. For instance, a “portion of land” can refer to a grower's entire property, a field, a plot of land, a planting region, a zone or management zone, and the like. Likewise, a portion of land can include one or more “sub-portions” of land, which refers to a subset of the portion of land of any shape or size. Various types and formats of data may be stored in the geographic database 135 for access by the other components of the crop prediction system 125, on which to perform one or more machine learning operations in order to train a crop prediction model, to predict a crop production for a portion of land, and to identify a set of farming operations that optimize crop production. The geographic database 135 can be organized in any suitable format. For example, data, including geo-referenced data, may be stored as flat files, columnar storage, binary format, etc. which may be accessed via relational databases, columnar databases, NoSQL stores, horizontally scaled databases, etc. The geographic database 135 is further discussed in conjunction with
The agricultural database 140 stores and maintains data describing agricultural characteristics associated with the planting, growing, and harvesting of a crop that may impact crop production. Various types and formats of data may be stored in the agricultural database 140 for access by the other components of the crop prediction system 125, on which to perform one or more machine learning operations in order to train a crop prediction model, to predict a crop production for a portion of land, and to identify a set of farming operations that optimize crop production. The agricultural database 140 can be organized in any suitable format, such as a columnar relational database. In one embodiment, the agricultural database 140 includes metadata that describes, for example, a product associated with a farming operation (e.g., a brand of fertilizer; a crop variant). In cases where metadata is unavailable, the crop prediction system 125 can infer the missing metadata based on other available metadata, including time, location, events that occurred prior to/with/after an operation, input or measured value having missing metadata, an identity of a corresponding grower, an identity of a corresponding farm, row spacing, a type of machine, and the like. In one example, a crop prediction model is trained on other samples for which the metadata is available and applied to samples with missing metadata, for instance using a random forest classifier, a k-nearest neighbor classifier, an AdaBoost classifier, or a Naïve Bayes classifier. The agricultural database 140 is further discussed in conjunction with
The normalization module 145 receives data in a variety of formats from the external databases 112, sensor data sources 114, image data sources 116, or other data sources and normalizes the data for storage in the geographic database 135 and the agricultural database 140 and use by the crop prediction engine 155. Due to the large number and disparate nature of prospective external data sources, data received by the normalization module 150 may be represented in a variety of different formats. For example, images received from a satellite and from a drone may be in different image file formats, at different resolutions, and at different scales (e.g., a pixel in each image may represent a different geographic distance). Likewise, rainfall measurement data received from a rain sensor at a field may include a first unit (such as inches) while rainfall estimate data from a weather monitoring entity may include a second unit (such as centimeters).
For a particular type of data, the normalization module 145 selects a common format, normalizes received data of the particular type into the common format, and stores the normalized data within the geographic database 135 and the agricultural database 140. In addition, the normalization module 145 can “clean” various types of data, for instance by upscaling/downscaling image data, by removing outliers from quantitative or measurement data, and interpolating sparsely populated portions of datasets. Based on the data format and corresponding method of normalization, the normalization module 145 can apply one or more normalization operations including but not limited to: standardizing the crop growth information to a common spatial grid and common units of measure; interpolating data using operations that include Thiessen polygons, kriging, isohyetal, and inverse distance weighting; detecting and correcting inconsistent data such as erroneously abrupt changes in a time-series of measurements that are physically implausible; associating geographic locations with pixels in an image; identifying missing values that are encoded in different ways by different data sources; imputing missing values by estimating them using values of nearest neighbors and/or using multiple imputation; and the like.
In one embodiment, the normalization module 145 generates, maintains, and/or normalizes metadata corresponding to data received from external data sources. Such metadata can include the source of the corresponding data, the date the corresponding data was received, the original format of the corresponding data, whether the corresponding data has been modified by a user of the crop prediction system 125, whether the corresponding data is considered reliable, the type of processing or normalization performed on the corresponding data, and other characteristics associated with the normalized data.
The database interface module 150 provides an interface between the components of the crop prediction system 125 and the geographic database 135 and agricultural database 140. For instance, the database interface module 150 receives normalized data from the normalization module 145 and stores the normalized data in the geographic database 135 and the agricultural database 140. The database interface module 150 may additionally modify, delete, sort, or perform other operations to maintain the geographic database 135 and the agricultural database 140. For instance, the normalization module 145 can receive and normalize an updated set of historic temperature data, and the database interface module 150 can replace the previous historic temperature data stored within the geographic database 135 with the updated normalized temperature data. Likewise, the database interface module 150 can generate a view table of data, such as historic corn harvesting data within the state of Illinois between 1988 and 1996 in response to a request received from a user of a client device 108 via the interface 130. The database interface module 150 additionally accesses the geographic database 135 and the agricultural database 140 to retrieve data for use by the crop prediction engine 155.
For example, when training a crop prediction model, the crop prediction engine 155 can request cotton fertilization information for plots of land with a low soil acidity via the database interface module 150. The database interface module 150 can query the “soil acidity” column within the geographic database 135 to identify plots of land associated with a below threshold soil acidity, and can query the agricultural database 140 to obtain fertilization information (such as type of fertilizers applied, quantity of fertilization applied, data of application, and resulting crop production) associated with the identified plots of land. The crop prediction engine can then provide the retrieved fertilization information to the crop prediction engine 155, which in turn can apply, for instance, a neural network to the fertilization information to generate a crop prediction model mapping low soil acidity and fertilization operations to crop production.
Likewise, if the crop prediction system 125 receives a request for a crop production prediction from a grower client device 102 for a particular field, the crop prediction engine 155 can request information associated with the particular field via the database interface module 150, which in turn can retrieve it from the geographic database 135 (e.g., geographic information associated with the particular field, geographic information associated with other fields within a threshold similarity to the requested field, etc.) and from the agricultural database 140 (e.g., agricultural information describing crop variants previously grown in the particular field and similar fields, farming operations performed on the previously grown crop variants, and corresponding crop production information). The database interface module 150 can then provide the requested and retrieved data to the crop prediction engine 155 for use in applying the crop prediction models to generate crop production predictions.
The crop prediction engine 155 trains and applies crop prediction models by performing one or more machine learning operations to determine predictions for crop production and corresponding sets of farming operations that result in the predicted crop production. The crop prediction engine 155 can request data from the various external data sources described herein for storage within the geographic database 135 and the agricultural database 140, and can perform the machine learning operations on the stored data. For example, the crop prediction engine 155 can apply a Bayesian network to information describing plots of land within 500 meters of a body of water and corresponding rice production in order to train a crop prediction model that maps proximity to water to rice production. The crop prediction engine 155 can also receive requests, for instance from a grower client device 102 or a broker device 104, to predict a crop production for a particular plot of land, a particular crop, and a particular set of farming operations. In addition to predicting the requested crop production, the crop prediction engine 155 can also identify a modified set of farming operations or an alternative crop that will optimize crop production. Likewise, a grower can simply identify a portion of land and request a set of farming operations to perform (including an identification of a type or variety of crop to plant) to optimize crop production, and the crop prediction engine 155 can apply one or more trained crop prediction models to information associated with the identified portion of land to identify the set of farming operations that optimizes crop production. The crop prediction engine 155 is described further in conjunction with
The crop prediction system 125 and other devices shown in
By generating crop production predictions and identifying farming operations to perform for particular portions of land, the crop prediction system 125 allows growers to quickly access information to optimize crop production. Crop production may be optimized for a current season or over a time period of multiple seasons. As used here, “crop production” can refer to any measure associated with the planting, growing, and/or harvesting of crops, including but not limited to crop yield for a current year or for multiple seasons, current or future profit, expected planting/growing/harvesting costs, soil health over one or more season, carbon sequestration, production at a particular date or within a range of dates (e.g., early or late maturing), composition profiles of crops (e.g., percent moisture, oil, protein, carbohydrate, or with a particular fatty acid profile, amino acid profile, or sugar content), and the like.
Up to hundreds or more agronomic, environmental, economic, and geographic factors may affect crop production, and the quantity and impact of information associated with these factors may be difficult or impossible for a grower to accurately and efficiently internalize and apply. The crop prediction system 125 can comprehensively account for this large quantity of crop production information, and can perform one or more machine learning operations identify a set farming operations and decisions for growers without requiring growers to spend the time manually accounting for this crop production information. The result is that the grower is able to efficiently harness the power of complex machine learning processes to identify farming operations that, when performed, can increase or optimize the grower's crop yield, overhead, and profitability. Further, as described below, the crop prediction system 125 can enable a grower to receive updated farming operations throughout the course of a planting season as crop conditions (e.g., weather, price of fertilizer, etc.) change, thereby allowing the grower to harness machine learning processes to account for unpredictable phenomena and conditions, and to further optimize crop production as a season progresses.
The input/output module 405 accesses information for use in training and applying crop prediction models. For instance, the input/output module 405 receives a request from a grower client device 102 requesting crop production prediction information and including information describing a field. In another instance, the input/output module 405 accesses the geographic database 135 and the agricultural database 140 to retrieve data for use by the training module 410 to train prediction models. The input/output module 405 can coordinate the transfer of information between modules of the crop prediction engine 155, and can output information generated by the crop prediction engine, for instance, crop production prediction information and/or a set of farming operations that optimize crop production.
The training module 410 trains crop prediction models by performing machine learning operations on training data accessed by the crop prediction system 125, for instance from the geographic database 135 and the agricultural database 140. For instance, the crop prediction models are generated based on geographic information describing various plots of land, agricultural data describing types and varieties of crops planted on the plots of land and farming operations performed on the planted crops, and harvest information describing the resulting harvest for the planted crops. As described above in conjunction with
The training module 410 can perform various types of machine learning operations to train crop prediction models using all or part of accessed training data or feature values of the training data as inputs to the machine learning operations. Various machine learning operations may be performed in different contexts to train the crop prediction models, and the crop prediction models can perform various machine learning operations when applied, including but not limited to: a generalized linear model, a generalized additive model, non-parametric regression, random forest, spatial regression, a Bayesian regression model, a time series analysis, a Bayesian network, a Gaussian network, decision tree learning, artificial neural networks, recurrent neural network, reinforcement learning, linear/non-linear regression, support vector machines, clustering operations, genetic algorithm operations, and any combination or order thereof. In one example, time series analysis operations performed by the training module 410 can include vector autoregression, ARIMA, and time-series decomposition.
The machine learning operations, when performed on input parameters describing a field or a crop variant, generate a crop prediction model for the field or crop variant associated with the input parameters. Crop prediction models can be generated upon receiving a request from a grower client device 102 for a crop production prediction, or can be generated in advance of receiving such a request. The training module 410 stores generated crop prediction models in the model store 415 for subsequent access and application, for instance by the crop prediction module 425.
The training module 410 may periodically update crop prediction models in response to a triggering condition. For example, the training module 410 can update a crop prediction model after a set amount of time has passed since the model was last updated, after a threshold amount of additional training data is received corresponding to the field and crop variant associated with the model (e.g., new data is received for fields with a threshold similarity to the field; new data is received for the crop variant; new data is received from the corresponding grower client device 102 about applied farming operations), or after a threshold amount of field information is obtained for an already-planted crop (e.g., a current crop growth rate, a pest infestation rate, etc.). In another example, the training module 410 can update a crop prediction model responsive to a market event (e.g., a midseason weather event that affects the availability of a crop supply, a greater-than-threshold increase or decrease in crop price, etc.).
In some embodiments, the training module 410 can update a crop prediction model responsive to an agricultural event (e.g., a planted crop achieves a plant growth stage, such as germination, flowering, and the like). Likewise, the training module 410 can update a crop prediction model responsive to a request received by the crop prediction engine 155 (e.g., by a grower or an agronomist). In some embodiments, the training module 410 updates the crop prediction models iteratively, such that a crop prediction output from a crop prediction model is incorporated into a training set of data used to train crop prediction models. For example, if a prediction model generates a set of farming operations identifying a crop variant to plant and a planting date range to optimize crop production, the training module 410 can incorporate the set of farming operations into a training set for use in training or retraining crop prediction models.
The model store 415 stores and maintains the crop prediction models generated by the training module 410. In one embodiment, the model store 415 stores the crop prediction models in association with a corresponding plot index uniquely representing the field or fields of the data used to train the model. The model store 415 can also receive and store updates to the models from the training module 410, and can provide stored prediction models, for instance in response to a request from the crop prediction module 425.
The farming operations store 420 stores data describing various farming operations that can be performed by a grower on a field. Farming operations can be associated with sets of information including an expected impact on a crop or a field, timing data describing when the farming operation should be performed, and a method of performing the farming operation (e.g., for farming operations requiring products such as pesticides and fertilizers, a method may identify one or more versions of available product). The farming operations store 420 can provide information describing farming operations for use as inputs to crop prediction models, for instance by the crop prediction module 425 when attempting to identify a set of farming operations that optimize crop production. Examples of farming operations stored by the farming operations store 420 can include:
The crop prediction module 425 receives a request to generate an optimized crop production prediction for a field (which can include multiple fields or plots of land, adjacent or otherwise) and applies one or more crop prediction models data associated with the field to determine a set of farming operations to optimize a crop production for the field. In one embodiment, the request is received from a grower via client device 102. In other embodiments, the request is received via a GUI generated by the interface module 130 and displayed on a client device of third party, such as a technology or service provider, a commodity trader, or a manufacturer of a good utilizing one or more agricultural inputs. For example, a technology provider can include a manufacturer of a technology such as an agricultural chemical, microbial composition, sensor, satellite, aircraft, unmanned aerial vehicle, land-based vehicle, land-based camera system, and the like. In such cases, “optimizing crop production” can refer to optimizing the use of a technology or service provided by such a third party (for instance, optimizing the cost of or resulting crop yield from using a technology or service), including the date and location of the use of a technology or service and any targeted field parameters associated with such use. In another example, a service provider can include a data provider (e.g., data describing weather, crop production, crop input use, imagery (drone, satellite, or land-based), data from a sensor, and/or commodity prices); an agronomist or other advisor; a service provider (e.g. grain marketing services), a broker or exporter, a procurement services provider, a delivery or transportation service provider, and the like.
In some embodiments, the request to generate an optimized crop production prediction is generated in response to conditions associated with a triggering event being satisfied. Examples of such triggering events include but are not limited to: a market event (such as an above- or below-threshold quantity of harvested crop being available for purchase), a contracting event (such as the grower and crop broker entering into an agreement wherein the crop broker obtains from the grower some or all of a crop to be harvested), a product supply event (such as the price of a particular fertilizer exceeding a threshold), a crop growth event (such as a growth rate of a planted crop exceeding a threshold), a weather event (such as a below-threshold amount of rain over a pre-determined time period), and the like. In some embodiments, the request to generate an optimized crop production can come from a grower or broker immediately before planting, shortly after planting, or mid-season, for instance in response to a grower manually adjusting one or more field parameters or farming operations previously provided by the crop prediction module 425. By applying a crop prediction model at various points throughout a growing season, the set of farming operations performed by a grower can be iteratively optimized, accounting for mid-season changes or events related to growing, land, or market characteristics.
Responsive to receiving the request, the crop prediction module 425 accesses geographic information associated with the field. The crop prediction module 425 accesses the model store 415 to retrieve one or more crop prediction models associated with the request, and applies the retrieved prediction models to the accessed geographic information. The crop prediction models can iterate through various combinations of farming operations to identify a set of farming operations that optimizes for crop production. In some embodiments, the type of crop production (e.g., crop yield, cost reduction, etc.) that the crop prediction models optimize for can be included within the request received by the crop prediction module 425, can be specified by a user associated with the crop prediction engine 155, can be a default crop production type, or can be selected based on any suitable criteria.
In some embodiments, a crop prediction model P used by the crop prediction module 425 can be represented as:
crop prediction=P(field1,field2,fieldx;farmop1,farmop2, . . . farmopy) Equation 1
In Equation 1, field parameters are represented by variables field1, field2, . . . fieldx, and farming operations farmop1, farmop1, . . . , farmopy. As used herein, a “field parameter” is any type of field information that describes a geographic or agricultural characteristic associated with the land, the environment, or the planting, growing, and harvesting of a crop. In some embodiments, the field parameters used as inputs to the crop prediction model are included within a request for prediction information. For example, a farmer can use a grower client device 102 to request prediction information for a crop planted at a particular portion of the farmer's field, and the farmer can specify the soil type of the field portion, historic crops planted at the field portion, and an available irrigation system for the field portion. In some embodiments, the field parameters are retrieved from the geographic database 135, the agricultural database 140, or an external source (such as an entity of
The crop prediction module 425 applies the prediction model P to the field parameters and a set of farming operations to generate a prediction of crop production for the field parameters and the set of farming operations. Continuing with the previous examples, for a specified field portion, soil type, historic planted crops, available irrigation, historic sunlight information, crop yield for similar fields, and expected future rainfall, the crop prediction module 425 can apply a corresponding crop prediction model that, when applied, performs one or more machine learning operations on these farming parameters to identify a set of farming operations and a predicted crop production for the field portion if the selected set of farming operations are performed. The machine learning operations performed by the crop prediction module 425 can iterate through multiple combinations of farming operations in order to identify a set of operations that optimizes predicted crop production. In some instances, the set of available farming operations are constrained by the resources available to the grower (e.g. farm equipment such as tractors or drones, labor, capital, field size, input availability or prices in the region comprising the land, etc.). For instance, the crop prediction module 425 can perform a random forest classifier or a gradient boosting operation to identify the set of farming operations that produces the optimized crop prediction without having to exhaustively iterate through every combination of possible farming operations.
In some embodiments, crop prediction models are applied to a particular crop type or variant, such as a crop variety specified by a grower. A “variant” of a crop or plant (or element thereof, e.g. a seed) represents a particular instance of natural or artificially introduced genetic or epigenetic diversity of a crop or plant. For example, a genetic variant may be a crop variety, a genetically modified trait (such as represented by transgenic events MON87460 (Genuity® DroughtGard™), DP73496 (Optimum® Gly), SYN-000H2-5, or genome engineering including genetic variants introduced by targeted nucleases such as a targeted nuclease transcription activator-like effector nuclease (TALEN), zinc finger nuclease (ZNF), clustered regulatory interspaced short palindromic repeats (CRISPR), CRISPR/Cas9, CRISPR/CPF1, and combinations thereof), or an epigenetic trait such as introduced by treatment with a DNA methyltransferase inhibitor such as 5-azacytidine, or a histone deacetylase inhibitor such as 2-amino-7-methoxy-3H-phenoxazin-3-one or genomic perturbation such as via tissue culture. In other embodiments, the crop prediction module 425 additionally modifies the crop type or variant when applying a crop prediction model to determine a crop type or variant that optimizes the crop production. In these embodiments, the crop prediction module 425 identifies a crop variant and a set of farming operations corresponding to the identified crop variant, for instance for display on the grower client device 102.
In some embodiments, a crop prediction model can be a neural network trained on geographic and agricultural data, including for instance, land characteristics, crop types planted, farming operations performed, and resulting crop productions. The resulting neural network can map combinations of geographic and agricultural inputs to resulting crop productions, including geographic, agricultural inputs, and crop productions (and combinations thereof) that weren't included in the training data. When the crop prediction module 425 applies the neural network to a set of field parameters (for instance, included within a request received from a grower or broker), the neural network can vary possible combinations of farming operations to identify a set of farming operations mapped to an optimized crop production. It should be noted that for the machine learning operations and crop prediction models described herein, an “optimized crop production” may refer to a maximum crop production over a threshold number of iterations or time. In other words, a predicted optimized crop production may refer to a local maximum crop production discovered over the course of applying a machine learning operation or a crop prediction model to a set of inputs, but not necessarily a global maximum over all possible combinations of farming operations.
In some embodiments, a crop prediction model can be a Bayesian classifier trained on geographic and agricultural data, including for instance, land characteristics, crop types planted, farming operations performed, and resulting crop productions. The resulting Bayesian classifier can identify a set of farming operations that optimizes a prediction crop production by 1) enumerating all possible combinations of farming operations and all possible outcomes, 2) determining the probability distribution of each outcome for each combination of farming operations (using a Bayesian model), 3) computing the expected utility for each outcome (e.g., a tradeoff of profit, risk, costs, and environmental impact), and 4) choosing the combination of farming operations with the highest expected utility. Accordingly, the Bayesian classifier can select a set of farming operations associated with a predicted crop production probability distribution that stochastically dominates the predicted crop production probability distributions associated with other possible sets of farming operations.
In some embodiments, a crop prediction model can be an ensemble machine learning model including one or more of a convolutional neural network, a spatial regression operation, a random forest classifier, and a partial least square regression operation trained on one or more of crop reflectance data, crop tissue samples, rainfall information, irrigation information, soil moisture information, solar radiation information, temperature information, and nitrogen application information. The resulting ensemble model can identify a set of operations that is likely to result in a particular protein content for wheat crops by 1) processing images (including image stitching and cloud cover correction) to obtain current season reflectance data, 2) joining the reflectance data with current season tissue sample data and rainfall/solar radiation time series data, and 3) selecting farming operations (including nitrogen application and irrigation operations) that are expected to result in the particular protein content. Accordingly, the ensemble model can identify a set of farming operations that, if performed, are expected to result in a particular wheat protein content based on current season conditions. It should be noted that in some embodiments, the ensemble model can also select an optimized wheat protein content, for instance based on current market prices, costs of requisite treatments, and the like, and can identify a set of farming operations expected to produce the optimized wheat protein content.
In some embodiments, a crop prediction model can be a multivariable regression model trained on one or more of historic planting dates, planting rates, harvest dates, weather conditions, and solar radiation. The resulting multivariable regression model can predict whether a crop replant will result in an optimized crop production, and can identify a type of crop (either the same crop or a different crop) to replant that will result in the optimized crop production. The multivariable regression model can predict a probable range of yields for a planted crop based on various conditions and characteristics of the crop (such as current crop growth rate, current and expected weather conditions, and planting date), and can likewise predict a set of probable yield ranges for replanting under various conditions (varying planting date, crop type, treatments applied, etc.) If a predicted probable yield range of the set of probable yield ranges stochastically dominates the predicted probable range for the planted crop, the multivariable regression model can then recommend a replant, and can identify a set of farming operations (including the type of crop to plant, planting date, and the like) that will optimize crop production for the replant.
In some embodiments, a crop prediction model can be a Bayesian model that includes Gaussian processes or splines, trained on historic soil samples, information describing trends in soil nutrient contents and composition, and information describing soil variation over geographic regions. The resulting Bayesian model can interpolate soil sample information over a portion of land, such as a grower's field, for instance using Markov Chain Monte Carlo sampling or variational inference estimations. After samples and corresponding locations are accessed for a particular portion of land, the Bayesian model can be queried for a soil characteristic or measurement (such as pH) at a particular location within the portion of land, and the Bayesian model can provide an inferred soil characteristic or measurement (or a probable range) in response.
Examples of other crop prediction models that perform one or more machine learning operations include but are not limited to:
As noted above, the crop prediction module 425 determines an optimized crop production by comparing multiple predictions from multiple sets of farming operations and/or field parameters. In one embodiment, the crop prediction module 425 identifies a crop production prediction and corresponding set of farming operations with a greatest expected utility. The expected utility may be determined by a number of factors, for instance prioritized based on user input from a grower client device 102 including yield, profitability, long-term impact to the field or environment (e.g., addition or reduction of nutrients to the soil), composition of the crop or of the field, and the like.
The output of the crop prediction models applied by the crop prediction module 425 may be formatted in a variety of ways. In some embodiments, the crop prediction module 425 outputs a measure of crop productivity for a particular set of farming operations. For example, the crop prediction module 425 can output a numerical value representing a predicted crop yield; a probability distribution (e.g., a 20% chance of a decrease in crop production and an 80% chance of an increase in productivity); a map overlay representing an area of land including a planting region corresponding to a request showing management zones of application of one or more farming operations and a predicted productivity corresponding to the management zones; a predicted cost/profit ratio per acre; a yield or profitability delta relative to similar or nearby groups of fields; a yield or profitability delta relative to historical practices or productivity of the same planting region; and the like.
In some embodiments, the crop prediction module 425 outputs a set of farming operations identified to result in an optimized crop production. For example, the crop prediction module 425 can output a crop type to plant, a planting date range, dates and quantities of nitrogen application, watering timing instructions, and the like. The crop prediction module 425 can modify a crop growth program or a set of farming operations identified by a grower, and can output the modified crop growth program or modified set of farming operations, for instance by highlighting the modifications made. For any type crop prediction model output, the interface 130 can cause a grower client device 102, an agronomist client device 108, or any other entity of
For example, a planting region 5151 located near a river 510 may have a higher soil moisture content than a second region 515A located farther from the river, and may be better suited to a different crop variant and set of farming operations than to the second region (e.g., the first planting region 5151 might require less frequent or intensive watering than the second planting region 515A; the second planting region 515A might be better suited to a hardier crop variant). In another example, a first region 515E may be located on a slope and experience a greater volume of runoff during rainfall than a second region 515F located at the peak of a hill. Accordingly, a crop prediction system 125 may prescribe a different crop variant and set of farming operations to the first region 515E than to the second region 515F despite the two regions being geographically close to each other. For instance, the first region 515E may require a more frequent application of pesticides to prevent pesticide dilution from the runoff during rainfall than the second region 515F.
The crop prediction system 125 iterates through multiple sets of farming operations 620 and identifies the set of farming operations associated with an optimized predicted crop production. In the example of
In the embodiment of
In the example of
The crop prediction system 125 iterates through multiple sets of updated farming operations 720 and identifies the set of farming operations associated with an optimized predicted crop production. In the example of
Each set of updated farming operations 720 is associated with a different predicted crop production. For instance, the first set of updated farming operations 720A is associated with an updated predicted production of 730 units, the second set of updated farming operations 720B is associated with an updated predicted production of 805 units, and the third set of updated farming operations 720C is associated with an updated predicted production of 790 units. In other words, while the set of farming operations 620C was determined before planting to represent an optimized set of farming operations and to result in a predicted production of 790 units, the same set of farming operations 720A is determined to result in a prediction production of only 730 units after the crop prediction model is re-applied mid-season. This discrepancy can be the result of a change in expected weather conditions, a market event, or an unexpected infestation of insects.
In the embodiment of
It should be noted that although reference is made in
A crop prediction system 125 accesses crop growth information 805 from one or more sources. The crop growth information can include geographic information, agricultural information, and crop production information. The crop prediction system 125 normalizes 810 the crop growth information and stores 815 the normalized crop growth information in one or more databases, such as the geographic database 135 and the agricultural database 140. The crop prediction system 125 trains 820 a crop prediction engine 155 by applying machine learning operations to the normalized crop growth information in the one or more databases to produce machine-learned crop prediction models. In some embodiments, the crop prediction models can be learned with or without human guidance, and can be learned using supervised machine learning, unsupervised machine learning, and/or reinforcement machine learning.
Responsive to receiving 825 a request to optimize crop productivity from a requesting entity, the crop prediction system 125 accesses 830 field information corresponding to the request. For example, field information corresponding to the request can include a plot index or other field location data, and information describing the conditions of the field, such as soil composition and moisture levels. The crop prediction system 125 applies 835 the crop prediction engine 155 to the accessed field information and a first set of farming operations (such as a set of farming operations selected by the requesting entity, or by the crop prediction engine itself) to produce a first predicted crop production.
The crop prediction system 125 then applies 840 the crop prediction engine 155 to the accessed field information and a second set of farming operations (such as a set of farming operations selected by the crop prediction engine) to produce a second predicted crop production. In one example, the second set of farming operations includes one or more farming operations that differ from the farming operations in the first set of farming operations (e.g., in identity, in application or lack thereof, in application method, in timing of application, in rate of application, or the like). If the second predicted crop production is greater than the first predicted crop production, the crop prediction system 125 modifies 845 the first set of operations based on the second set of operations. The crop prediction system 125 then provides 850 the modified set of farming operations to the requesting entity such that the modified set of farming operations may be performed 855 by the requesting entity or another entity.
In response to request for predicted crop production information, a crop prediction system 125 accesses 905 field information describing a portion of land and applies 910 a crop prediction engine 155 to the accessed field information. For example, the crop prediction engine 155 applies a Gaussian network machine learning model to the accessed field information in order to iterate through various combinations of farming operations to predict corresponding crop productions. Based on an output from the crop prediction engine 155, the crop prediction system 125 selects 915 a set of farming operations to optimize crop productivity for the portion of land and modifies 920 a user interface displayed by a client device associated with the request for predicted crop production information to displayed a crop growth program for the portion of land based on the selected set of farming operations.
The storage device 1008 is any non-transitory computer-readable storage medium, such as a hard drive, compact disk read-only memory (CD-ROM), DVD, or a solid-state memory device. The memory 1006 holds instructions and data used by the processor 1002. The pointing device 1014 may be a mouse, track ball, or other type of pointing device, and is used in combination with the keyboard 1010 to input data into the computer 1000. The graphics adapter 1012 displays images and other information on the display 1018. The network adapter 1016 couples the computer system 1000 to a local or wide area network.
As is known in the art, a computer 1000 can have different and/or additional components than those shown in
As is known in the art, the computer 1000 is adapted to execute computer program modules for providing functionality described herein. As used herein, the term “module” refers to computer program logic utilized to provide the specified functionality. Thus, a module can be implemented in hardware, firmware, and/or software. In one embodiment, program modules are stored on the storage device 1008, loaded into the memory 1006, and executed by the processor 1002.
As described above, the crop prediction system 125 can access information describing geographic and agricultural characteristics of a portion of land, and can perform one or more machine learning operations to identify a set of farming operations that, if performed, is expected to optimize crop production. By providing insight into a predicted crop production, various entities (such as a grower, a crop broker, a crop recipient, technology manufacturer, services provider, and an agronomist) are better able to evaluate risks and benefits in view of an expected crop productivity, and can perform various actions in view of those risks and benefits.
For a grower, accessing predicted crop production information can better inform the grower about which crop types and variants to plant in order to maximize end-of-season or future season profits, about which crop types and varieties to plant in order to minimize crop treatment and watering costs, about the effects of reducing crop treatment and watering costs on the expected crop yield, about the effects of storing a crop after harvest, about the long-term benefits of planting a cover crop, and the like. Having access to such information can beneficially enable growers to efficiently and profitably allocate resources, improve crop yield stability, reduce or account for short- and long-term risks, and evaluate expected market conditions months or years in advance.
Without access to such crop prediction information, growers may wait until late in a growing season to enter into a contract with a crop recipient in order to ensure they will avoid penalties for being unable to satisfy the conditions of the contract due to a lower-than-expected crop yield, or to seek a higher price for a harvested crop. In instances where many growers saturate the market late-season, crop recipients may be able to extract more favorable contract terms, to the detriment of the growers. Further, crop recipients may have access to a broader view of market conditions and may thus have a better understanding of the direction of market-wide yields, creating an information asymmetry that benefits crop recipients. In contrast, having access to such crop prediction information can enable a grower to close the information deficient with crop recipients and to enter contracts with crop recipients or crop brokers early in the growing season, at a time when fewer growers are willing to enter into contracts, enabling the grower to potentially 1) extract more favorable contract terms, 2) to optimize profit or another measure of crop production per unit of land, and/or 3) to provide the grower with access to resources (such as working capital or a contract down payment) resulting from an early-season agreement with a crop broker or recipient.
For a crop recipient, such as a food distributor, grocery store chain, or restaurant, accessing predicted crop production information can better inform the crop recipient about expected availabilities of particular crop types and variants. In turn, this can enable a crop recipient to evaluate abundance or scarcity of a desired harvested crop within the market, to evaluate an expected price for the desired harvested crop, and to reduce risk when entering into contractual agreements with growers or brokers based on the expected price. Likewise, predicted crop production information can enable a crop recipient to evaluate alternative crop types and varieties in the event that a desired harvested crop is too scarce or expensive. For example, a vegan energy bar maker can adjust a recipe for the bar prior to manufacture if a necessary ingredient is unlikely to be available or is likely to be prohibitively expensive at the end of a growing season.
A crop broker can leverage predicted crop production information to better evaluate expected harvested crop availability and costs in order to establish contracts with growers and or crop recipients. For example, a crop broker can enter into a contract with a grower at the beginning or just before a growing season with terms determined using one or more crop prediction models or machine learning operations as described herein. For instance, the contract can require:
For example, a broker can enter into a contract with a grower for a soybean crop harvest. The grower can be required to sell 80% of her crop to the broker at a rate of $9.50/bushel, determined by applying a crop prediction model that predicts end-of-season soybean market costs. The broker can be obligated to provide products and working capital to the grower over a series of months corresponding to key phases of the lifecycle of the soybean crop. For example, payments of working capital for the soybean crop may be made in three installments: 1) 15% of the expected value of the crop paid two weeks before planting, 2) 15% of the expected value of the crop after the emergence of 8+ leaves on a majority of the plants, and 3) 20% of the value of the crop after flowering has begun on a majority of the plants. Alternatively, 70% of the expected value of the crop can be paid at the time of crop storage, with the balance due upon delivery of the crop. The total expected value of the crop, and thus the value of each working capital installment, can determined by applying the crop prediction model at the time of each installment condition. For instance, the crop prediction model can be applied two weeks before planting to determine the first installment paid to the grower, can be applied again after a majority of the plants have 8+ leaves to determine the second installment paid to the grower, and can be applied again after a majority of the plants have flowered to determine the third installment paid to the grower.
Other entities can leverage the crop prediction models described herein within a market context. For instance, an agronomist can use crop prediction models that identify mid-season crop treatments that increase an end-of-season crop value more than the cost of the crop treatments. The agronomist can then market such advice to growers, beneficially increasing the grower's profitability and enabling the agronomist to charge for such advice. Likewise, an insurer can use crop prediction models to calculate crop risks, and can in turn calculate the costs and coverage of insurance policies for growers with greater accuracy than without access to the crop prediction models. In an additional example, a technology manufacturer or service provider may partner with a grower, agronomist, and/or crop broker to test their products on one or more growers' farms or with a dataset comprising data from one or more growers' farms. The crop prediction models may be utilized to identify and validate a set of farming operations and field parameters with which their services or technologies are most efficaciously deployed. It should be noted that any other suitable entity can apply the crop prediction models described herein, and that the examples given herein are intended to be illustrative and not limiting in any way.
