Bulking agents may benefit seed planting for plant species that require a low volume of seeds (i.e., a low pound of seed per acre ratio). In some instances, the bulking agents, which generally cost less than the seeds, may optimize a resultant plant density allowing the crop to better fight diseases and/or reduce lodging. Ultimately, the result is a higher quality crop with an increased yield. However, traditional bulking agents may be limited to a particular benefit, require significant modifications based on the soil type/texture, and/or require significant modifications based on the type/quantity of seed being planted.
Therefore, there remains a need for a bulking agent that provides the traditional benefits (e.g., optimized plant density) while also requiring fewer modifications based on the soil and/or seed being planted.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify all key features or essential features of the claimed subject matter, nor is it intended to be used alone as an aid in determining the scope of the claimed subject matter.
A first embodiment concerns a method of applying a seed with a compost bulking agent. The method may include adding an amount of compost bulking agent to an amount of seed. In some embodiments, the mixture of seed and compost bulking agent may be mixed in a ratio from about one (1) pound of seed to about four (4) pounds of compost bulking agent to a ratio of about one (1) pound of seed to about twelve (12) pounds of compost bulking agent. In some embodiments, the mixture of seed and compost bulking agent may be mixed in a ratio from about one (1) pound of seed to about one and a half (1.5) pounds of compost bulking agent to a ratio of about one (1) pound of seed to about thirty-nine (39) pounds of compost bulking agent. In some embodiments, the compost bulking agent may be added to the seed in an amount of, from about from about 125% to about 1500% per weight of seed, from about 400% to about 1200% per weight of seed, or from about 200% to about 400%.
Another embodiment concerns a method of applying a seed/compost bulking agent mixture to soil. The method may include applying seed/compost bulking agent mixture to an area of soil at an amount of from about 40 pounds per acre of soil to about 100 pounds per acre of soil.
The detailed description is set forth with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical items or features.
This disclosure describes, in part, methods of adding a compost bulking agent to seed. In some embodiments, the compost bulking agent may be added to the seed prior to planting the seed or “seeding”. In some embodiments, the compost bulking agent may be added to seed such that a substantially reduced amount of seed is needed to adequately plant an area. Traditionally, seeds that may be planted in low volumes (e.g., a seed volume of less than 10 pounds per acre), such as, but not limited to, canola, mustard, sunflowers, etc., may benefit from the use of bulking agents to provide better seed placement and distribution. In some instances, this is because most seed planting methods (e.g., conventional or no-till) require seed amounts of 40 pounds per acre or greater to accurately spread the seed. The result of adding a bulking agent may optimize seed placement and distribution which in turn may decrease resultant crop diseases and produce better crop yields.
Furthermore, traditional bulking agents may be used for an additional specific benefit apart from providing better seed placement and distribution. For instance, elemental sulfur or other soil amendments may be used as a bulking agent to alter the pH of the soil. However, the amount of sulfur to add to seed as a bulking agent is highly dependent on soil texture and/or the needs of the seed being planted. In addition, it is generally useful to apply and incorporate sulfur into the soil at least a year before planting to allow the sulfur time to react and alter the soil pH before planting. Thus, traditionally a user must carefully select the quantity of bulking agent based on the soil type/texture, type of seed being planted, and/or time of application of the bulking agent in order for the bulking agent to provide the specific additional benefit.
As described herein, a compost bulking agent may be added to seed to provide better seed placement and distribution. In some embodiments, the compost bulking agent may be a solid pelletized compost which may include but is not limited to yard waste (grass trimmings, leaves, prunings, etc.), food waste, wood waste, agricultural residues (mint, cull fruit, cull hop residue, grape pumice, etc.), manures, biosolids (e.g., an organic product of a wastewater treatment process), and so forth. In some embodiments, the compost bulking agent may comprise from about 15% to about 45% of mint or from about 25% to about 35% of mint. According to certain embodiments, the compost bulking agent described herein may comprise at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50% of mint. As described below, in some embodiments, the compost bulking agent may be added to seed in any ratio such that a seeder may accurately spread a low volume of seed. Furthermore, the compost bulking agent/seed mixture may provide several benefits to the resultant crop and/or user.
For instance, the compost bulking agent may cost substantially less than other bulking agents and/or seeds. The compost bulking agents described herein are organic and non-chemical. Moreover, because the composts described herein are organic in nature, the composts may resist runoff thereby greatly reducing the amount of material that leaches into waterways. The methods described herein may allow for a substantially reduced amount of fertilizer(s) to be used while resulting in substantially the same or improved crop yield over traditional seeding methods. According to certain embodiment, the methods described herein provide a crop yield that is at least 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50% or greater than crop yields seeding with traditional bulking agents.
As mentioned above, in some embodiments, the compost may be a solid. Moreover, when solid, the compost may be in the form of a pellet. When in pelletized form, the pellets may be made via any known method. For example, the pellets may be made by charging a thick liquid of paste form of the compost into a hopper of an extruder. The paste may then be extruded through a number of openings and cut to the desired size. The pellets may then be dried to a moisture content of less than about 15 weight percent. Care should be taken when drying so as not harm beneficial microbes in the pellets.
According to an embodiment, the compost bulking agent may be added to the seed in an amount of from about from about 125% to about 1500% per weight of seed, from about 400% to about 1200% per weight of seed, or from about 200% to about 400%. In some embodiments, the seed and compost bulking agent may be mixed in a ratio from about one (1) pound of seed to about four (4) pounds of compost bulking agent to a ratio of about one (1) pound of seed to about twelve (12) pounds of compost bulking agent. In some embodiments, the mixture of seed and compost bulking agent may be mixed in a ratio from about one (1) pound of seed to about one and a half (1.5) pounds of compost bulking agent to a ratio of about one (1) pound of seed to about thirty-nine (39) pounds of compost bulking agent. Exemplary low volume seeds (e.g. a seed volume of less than 10 lbs per acre) may include, but are not limited to, canola, rapeseed, safflower, camelina, crambe, cotton, mustard, and sunflower. In some embodiments, seed may include vegetable seed (e.g., carrot seed, lettuce seed, etc). However, it is to be understood that the described methods are not limited to low volume seed. In some embodiments, the method of using the compost described herein as a bulking agent may be implemented with other seed, such as, but not limited to wheat, barley, corn, rye, soybeans, hay, sorghum, rice, etc.
According to certain embodiments, the starting materials which may be biologically decomposed to form the compost bulking agent may include but are not limited to yard waste (grass trimmings, leaves, prunings, etc.), food waste, wood waste, agricultural residues (mint, cull fruit, cull hop residue, grape pumice, etc.), manures, Biosolids, etc.
In some embodiments, a user may use a singulating planter in order to drop a single seed in a predetermined location rather than dropping multiple seeds at the location. The desired result of a distance between each single seed of this singulating type planting may yield resulting plants that a spaced at a distance known to increase plant spacing efficiency (e.g., 4-19 plants per square foot) and produce a higher crop yields. In many cases, the size of low volume seed is smaller than high volume seeds. For instance, a canola seed is smaller than a wheat seed. Furthermore, the singulating planters may have a difficult time placing a single seed of the smaller low volume seed types. As such, a user may use the compost bulking agent to bulk the low volume seed in the singulating planters in order for the user to plant the small, low volume seed at a desired pounds per acre (e.g., 40 pounds per acre).
According to certain embodiments, a chemical fertilizer, a mineral fertilizer, a soil amendment, another compost agent or a mixture thereof may be added to the soil before, after or while the compost bulking agent/seed mixture is being added to the soil. In some embodiments, where a fertilizer (solid and/or liquid) is applied in addition to the compost bulking agent/seed mixture, the fertilizer may be added in amount that is about ⅓ to ½ times less than the amount of fertilizer that would be added if the fertilizer was added to the soil without the application of the compost bulking agent while resulting in at least the same crop growth or yield. According to certain embodiments, applying a combination of the compost bulking agent and a substantially reduced amount of fertilizer results in a crop yield that is at least 0%, 5%, 10%, 15%, 20% or greater than if the fertilizer was applied without the compost bulking agent.
As used herein the term “compost” or “compost bulking agent” is meant to include any variety of organic material, which may be animal or vegetable in origin, and which through biological, such as microbial (bacterial, fungal, and actinomycetes) action under controlled conditions to promote aerobic decomposition.

The method of adding a compost bulking agent to seed may be implemented in a number of ways. Example implementations are provided below with reference to the following figures.
At 202, an area of soil to be seed may be determined. For instance, a user may determine that they would like to seed ten acres of soil with a particular seed such as canola seed. At 204, a volume of a seed may be mixed with a volume of a compost to create a seed and compost mixture. For instance, a user may mix an amount of seed needed to plant the determined area of soil with compost. In some embodiments, the compost may be added to the seed in a ratio from about one pound of seed to about four pounds of compost to a ratio of about one pound of seed to about twelve pounds of compost. In some embodiments, the mixture of seed and compost bulking agent may be mixed in a ratio from about one (1) pound of seed to about one and a half (1.5) pounds of compost bulking agent to a ratio of about one (1) pound of seed to about thirty-nine (39) pounds of compost bulking agent. At 206, the seed and compost mixture may be added to the area of soil, wherein the seed and compost mixture may be applied to the area of soil at an amount from about one pounds per acre to about fifteen pounds per acre, or from about four pounds per acre to about ten pounds per acre.
At 308, the amount of seed and the compost may be applied to the area of soil. In some implementations, an amount of seed/compost bulking agent mixture may be applied to an area of soil at an amount of from about 40 pounds per acres to about 100 pounds per acre of soil.
Five pounds of canola seed, per acre, were mixed with 40 lbs, of compost pellet bulking agent. The mixture was planted using a planter. The result was uniform planting with better singulation of the seed compared to planting seed without the compost pellet bulking agent. Less seed was applied per acre to obtain the same amount of coverage due to the uniform planting. The germination rate remained the same.
Although the application describes embodiments having specific structural features and/or methodological acts, it is to be understood that the claims are not necessarily limited to the specific features or acts described. Rather, the specific features and acts are merely illustrative some embodiments that fall within the scope of the claims of the application.
