A stall vacuum trailer system to secure to a vehicle, the system includes a trailer supported by a frame and having a cargo compartment to receive particles therein; a vacuum machine supported by the frame, the vacuum machine having a motor; a fan device to mulch a substrate into the particles; and a hose extending from the fan and to extend to a rear of the cargo compartment; the fan device creates a vacuum effect to pull the substrate through the hose and further through the fan device and into the cargo compartment; the substrate is mulched into particles while entering the cargo compartment.

A biodegradable film is prepared from a composition that includes a copolyester obtained by extrusion reaction of a branched aliphatic-aromatic copolyester derived from monomer a, monomer b, monomer c and monomer d with an organic peroxide. The film can be completely degraded into small molecular products such as carbon dioxide, water and the like under natural or composting conditions. Moreover, the film can be prepared having a thickness of 4-50 μm as required, and its mechanical properties can reach the same level as or even better than those of LDPE film.

The invention is a completely biodegradable, bio-based plant and seedling mulching device that inhibits the growth of noxious weeds while allowing the flow of water to the root zone of the plant or seedling.

A crop prediction system performs various machine learning operations to predict crop production and to identify a set of farming operations that, if performed, optimize crop production. The crop prediction system uses crop prediction models trained using various machine learning operations based on geographic and agronomic information. Responsive to receiving a request from a grower, the crop prediction system can access information representation of a portion of land corresponding to the request, such as the location of the land and corresponding weather conditions and soil composition. The crop prediction system applies one or more crop prediction models to the access information to predict a crop production and identify an optimized set of farming operations for the grower to perform.

A cross-linked, water absorbent polymer is mixed with desirable additives and coated to prevent water absorption to create a blend that is added to water injection systems for turf and soil maintenance. The coating is rinsed off the water absorbent polymer resulting in expansion of the polymer into a gel-like substance. The water absorbent polymer has the ability to retain water and nutrients in the soil preventing nutrient runoff and reducing watering frequency. Injection of the water absorbent polymer directly into soil reduces waste and reduces hazard caused by slippery material left on soil surfaces. The method and system for mixing and injection into soil is disclosed.

A method and apparatus for collecting agricultural manure in a confined animal feeding operation includes a separator which receives heavy manure removing particulate from suspension to produce light manure. Heavy manure is collected to a volume of heavy manure sufficient to substantially fill the first tank. Within the first tank, particulate migrates, due to the influence of gravity to form a layer containing manure comprising a lesser density of particulate than is present in the volume of heavy manure. Additional heavy manure buoys the layer such that the upper surface exceeds a height of a weir. The weir is situated in a channel communicating between the first tank and a second tank configured to receive light manure from the separator.

A cutter holder has two limbs extending at an angle to each other. A cutter is mounted on one side of the cutter holder. An opposite side of the cutter holder has a prism-shaped cavity defined thereon. The cavity has a V-shape cross-section having a recessed groove at a base of the V-shape. A center line of the recessed groove is laterally offset from a center line of the cutter holder.

Provided is a method for planting a mixed forest of yew trees and fig trees. Yew trees and fig trees are interplanted based on characteristics of yew trees and fig trees. A seedling bed method is used in the plain zones, and a terrace field method is used in mountain zones in order to improve land utilization rate and make full use of complementary advantages of ecological niches. In the present disclosure, ground and underground spaces on tree growing site are fully used. Fig trees grow fast and have large leaves, thus shading part of sunlight for yew trees and savings costs required for building shade shelters for yew trees. By using the method for constructing a mixed forest in the present disclosure, the constructed mixed forest not only allows for increase of biomass, but also provides higher paclitaxel content in yew trees than that in pure forest.

The Weed Blocking Mini Conservatory is a device which blocks weed, plant, root, and some predator encroachment. When connected to the light penetrating top, the invention allows a protected area for photosynthesis, seed and rooting cultures, with containers, mediums, and associated accessories and garden storage. The device functions as a hollow, washable, durable container in which both living and nonliving items can be enclosed. Its structure blends harmoniously with architecture and outdoor environments. It is safe for use around humans and pets. It is also adaptable to large scale garden use.

A dormancy control system for use with plants such as fruit trees, nut trees, and perennial berry bushes planted in commercial settings. The dormancy control system employs vertical shade structures to control the dormancy of plants such as fruit trees, nut trees, and perennial berry bush crops. The dormancy control system results in dramatic increases in crop yield, and may be coupled with orchard planting directional orientation, evaporative cooling systems, and chemical and hormone based spray applications
