Agriculture is clearly important to the whole of humanity. Agriculture is a primary source of oxygen creation, core to hosts of economies and industries around the globe, and one of several primary sources of the world's food supply.
Industrial, large-scale, commercial farms and individual, small-scale residential gardens share a number of common challenges and traits. At both ends of this spectrum, the successes of agricultural yield are primarily functions of water, nutrients, pest control, and ambient temperature, humidity, and sunlight. Advances have been made in each of these areas from creative ways to reduce water wastages and recapturing of water for reuse, innovative nutrient supply systems, non-chemical approaches to pest control, artificial lighting, and even indoor-farming environments and methods. With implementation of these, and many other innovations, agricultural yield has improved drastically as has the hardiness of vegetation in agriculturally suboptimal environments. But hosts of challenges remain.
The process of watering in all of its most common forms involves dripping, pouring, sprinkling or other mechanisms of delivering water to the soil, wherein it enters the soil and seeps into the ground, thereby providing the roots of the vegetation access to needed water.
Lawns, for instance, have relatively shallow root systems. A large percentage of the watering of commercial and residential lawns ends up seeping below or beyond the reach of the roots, thus being wasted. Another problem is that the water that seeps below the roots is then available for deeper roots of unintended competitive vegetation such as many varieties of weeds.
In addition, the moistened soil loses some of its water to evaporation into the atmosphere, thus providing no benefit to the vegetation. And still further, any pest, harmful chemicals, or even competitive root systems could invade the water absorption zone of the intended target vegetation and compete for water, nutrients, and other important properties. Some exogenous forces can even potentially attack the vegetation itself.
Grade school science classes often teach students about vegetation by having the children grow small, hardy plants in glass agricultural yield jars. The inventor extends this well-understood glass agricultural yield jar concept in a series of novel innovations described herein so as to take a modified approach wherein the aforementioned challenges are specifically addressed.
These, along with several other problems, are just some of the challenges large and small-scale farmers and landscapers must address. Here, several solutions to the aforementioned problems are proposed.
One aspect of the invention resides in an agricultural yield pod and an agricultural yield pad with root membrane overlay and a method of attaining an agricultural yield. It should be understood by those skilled in the art that the pod or pad is a three dimensional containment area of virtually any size and volume.
The method includes:
The boundary prevents seepage of the water and nutrients beyond the boundary from within the confines. The boundary reduces evaporation of the water and nutrients from the confines over what would otherwise be the amount of evaporation without the boundary. The boundary retains the water and nutrients within the confines. The boundary is made of an agriculturally and environmentally friendly material whose presence is harmless to the surrounding environment. The boundary may be insulated.
In the case of the agricultural yield pod 10, the boundary includes a base, a sidewall and a top, the top having two access ports spaced apart from each other. In the case of the pad, the boundary includes a base and a sidewall with the root membrane overlay serving as the top.
Further, the agricultural yield pod 10 and agricultural yield pad 30 allow for precise control over the volume of water and nutrients provided to the plants to ensure entirely optimal water and nutrient conditions.
Whether the agricultural yield pod 10 or agricultural yield pad 30 is made out of glass or other agriculturally and environmentally friendly materials, and whether made for small household applications or large scale industrial applications, the drastic reduction in water and nutrients required to sustain the vegetation, reduction of the threat of competitive vegetation and external chemicals to the roots and vegetation, and increase in efficiency for the roots to access nutrients and water solve numerous common issues across the agricultural space.
For a better understanding of the present invention, reference is made to the following description and accompanying drawings, while the scope of the invention is set forth in the appended claims.

Encapsulated Agricultural Yield Pod
An agricultural yield pod 10 of any shape (cube, spherical, oblong, etc.) is made of any environmentally compatible and agriculturally compatible medium such as glass, with several ports, is introduced. The agricultural yield pod 10 has a bottom 12, sidewall 14 and top 16 that together constitute a boundary defining an inner cavity. The top 14 has at least two ports that are:
The agricultural yield pod 10 may have two additional ports that serve additional purposes while also solving additional problems, namely:
Turning to
To drain contents from the interior bottom of the unit without the optional drainage ports, an extension tube 28 from the water and nutrient port 18 can be added. See
The agricultural yield pod 10, as presented in
Seeds or saplings can be planted through the vegetation growth port 20 (or neck) or via the top 16 if the top 16 is configured to be removable. Water can be delivered through the vegetation growth port 20 (or neck) and/or through the water and nutrient port 18, and/or through the optional rain/sprinkler water entrance port 22. The water and nutrient port 18 can have a connection valve attached wherein a garden hose, PVC pipe or any other water delivery mechanism can be attached such that (i) a measured amount of water can be delivered when needed, and (ii) the water will never be exposed to the atmosphere such as in typical sprinkler systems and thus be delivered more efficiently directly into the growth medium.
As water is introduced to the agricultural yield pod 10, it cannot seep beyond the boundary of the agricultural yield pod 10 and thus solves the problem as illustrated in
By placing a cap over the water and nutrient port 18 or connecting a garden hose or PVC pipe to the end of this port 18, the problem of evaporation is vastly reduced as very little of the moistened medium is exposed to the air. Furthermore, variations of the agricultural yield pod 10 can be constructed with elongated water and nutrient port 18 and elongated Vegetation Port so that the body of the agricultural yield pod 10 can be buried deeper below the ground surface, such as below the frost line, or in other protective medium to better control temperatures. Moreover, variations of the agricultural yield pod 10 can be constructed with multiple Vegetation Ports to allow multiple plants in a single encapsulated ecosystem. See
By extending the agricultural yield pod 10 to have many vegetation ports with one or more water and nutrient ports 18, all the water introduced cannot seep beyond the boundary of the agricultural yield pod 10 and thus can more effectively provide water to a wide array of vegetation simultaneously. By angling and curving the floor of the agricultural yield pod 10, any water that seeps down from the water and nutrient port 18 will tend to flow toward the center of the agricultural yield pod 10, thereby providing equal access to the water for all roots throughout the agricultural yield pod 10.
Various shapes of the agricultural yield pod 10 and various positions and counts for each type of port allow for many different kinds of extensions, all while keeping the contents of the agricultural yield pod 10 segregated from the surrounding environment. As such, any external forces, such as unwanted chemicals, pests, competitive vegetation, and the like are prevented, as is the problem of evaporation. Thus, lower amounts of water will be used while keeping the roots and the vegetation in an improved and controlled environment.
In the case of unhardy growth, which arises in some vegetation that is sensitive to some weather conditions and thus not hardy year round, such vegetation is expected to die during weather incompatible for its species. To extend the length of the season for such vegetation, an insulated version of the agricultural yield pod 10 can be constructed wherein a housing or an outer agricultural yield pod 10A contains an inner agricultural yield pod 10B and a gap 29 between is filled with insulation to maintain target content temperatures. For instance, the agricultural yield pod 10 may be double walled 10A, 10B with a cavity between that defines the gap. See
Variations include the gap being an empty cavity containing a warmer such as a conventional electric warmer, or cooler, a pump that circulates warm or cooler water for a timed cycle, or other external means of adding or removing heat. This gap can be filled via port 18B with temperature controlling liquids such as water, antifreeze, dry ice, air, or other agents. See
Encapsulated Agricultural Yield Pad
A related extension of the agricultural yield pod 10 is the agricultural yield pad 30, which can be constructed for large surface areas of vegetation such as lawns. Like the agricultural yield pod 10, the various surfaces (bottom 32 and sidewall 34) of the agricultural yield pad 30 keep water from seeping beyond the roots, and thus an agricultural yield pad 30 can be constructed in much the same fashion. See
This agricultural yield pad 30 may have many vegetation ports but need not be constructed with vegetation necks that protrude upwards for use in applications such as lawns. Instead, a holed root membrane overlay 36 is used that is strictly a plate with holes through which the vegetation grows. The holed root membrane overlay 36 can be attached either at the top edge of the sidewall 34 of the pad 30, as illustrated in
When the holed root membrane overlay 36 is attached in the middle, as in
The holed root membrane overlay 36 can be lifted out of the agricultural yield pad 30 or hinged onto the side of the agricultural yield pad 30 so it be angled out. Any vegetation, such as carrots or beets, growing in the lower zone of the agricultural yield pad 30 can be automatically harvested by lifting the holed root membrane overlay 36. Furthermore, by being able to lift the holed root membrane overlay 36, such allows the user to clean out the contents of the lower zone of the agricultural yield pad 30 and put in fresh growth media. By then replacing the holed root membrane overlay 36 back into the pad, the user can either plant seeds or saplings directly into the holes or place another layer of growth medium above the holed root membrane overlay 36 and plant seeds of saplings in this upper zone.
A more complex version of the agricultural yield pad 30 can be constructed where the holes of the holed root membrane overlay 36 have tubes protruding into the lower zone of the pad. These tubes, or root direction channels 38, direct the root growth and channel water, and allow for the roots to grab onto surfaces when such vegetation requires, such as is often beneficial for residential lawns. See
When grass seeds or multiple plants are growing within the agricultural yield pad 30 with root direction channels 38, as in
In each variation of the agricultural yield pod 10 and agricultural yield pads 30, with and without the holed root membrane overlay 36 and with and without the root direction channels 38, the growth medium (e.g., soil) and the vegetation (or seeds) remain segregated from the surrounding environment. This segregation prevents water from seeping beyond its boundary, reducing evaporation, maximizing utilization of the nutrients within the growth medium, and increasing root density per cubic unit of volume.
As illustrated above, the agricultural yield pod 10 and agricultural yield pad 30 configurations serve direct purposes, solve common problems, and provide a number of areas of value to users. As user needs differ, the following preferred embodiments showcase several common and intended applications.
Farming
Typical farming applications have vegetation of many sizes with many water and nutritional needs. The agricultural yield pods 10 and pads 30 can be constructed to dimensions based on the sizes of the root systems of the intended vegetation. Rather than rely on the typical sprinkler and drip irrigation systems so common on farms, watering hoses can be attached directly to the water and nutrient ports 12 rather than to sprinkler systems, thus reducing the water loss associated with these standard watering methods, and be able to accommodate farming land areas other than circular so often used based on the center pivot irrigation systems.
Further, excess water that may accumulate in the agricultural yield pods 10 or pads 30 can be removed via the drainage ports and stored or given to other vegetation, thus reducing water wastage and total water consumption. Since the contents of the agricultural yield pods 10 and pads 30 are encapsulated from the surrounding ground, there is a reduced need for chemicals such as weed killers.
Also, each agricultural yield pad 30 and agricultural yield pod 10 can be independently tested for nutrient and soil chemical levels and thus targeted remedies can be implemented. Agricultural yield pods 10 and agricultural yield pads 30 can even be transplanted as a whole without disturbing its contents by lifting and moving the entire pod or pad. This allows for repositioning entire sections of crops, if ever needed, and even moved indoors for multi-level indoor farming, such as vertical stacking of pads on shelves 40, as in
Typical farming and harvesting includes moving people and equipment to the vegetation for inspection and harvesting of the growth. The agricultural yield pods 10 and pads 30 with crops can be removed from the ground and sent via conveyor belt or other transportation means to the farmer or harvester for processing, hence bringing the crops to the harvester rather than the harvester to the crops.
Tree Bracing
Groves
Groves of fruit trees, vineyards, and other large growth can vastly benefit by each growth having its own agricultural yield pod 10 as in
Residential
Many homeowners have lawns requiring frequent watering, nutrient treatment, and care. By having the lawn grow within an agricultural yield pad 30, homeowners will reduce water usage while also only providing nutrients to the encapsulated soil. The agricultural yield pad 30 would position the holed root membrane overlay 36 either in the middle with soil above and below the holed root membrane overlay 36 as in
While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the scope of the present invention.
