Abstract:
Disclosed are a special fertilizer for intercropping maize and peanuts and a cultivation method for maintaining soil organic carbon (SOC) balance, belonging to the technical field of SOC balance. The special fertilizer for intercropping maize and peanuts includes the following raw materials: coated urea, heavy superphosphate, ammonium sulfate, fermented soybean meal, bentonite, sodium molybdate, borax, humic acid, ammonium dihydrogen phosphate, plant ash and zinc sulfate heptahydrate. The cultivation method includes the steps of land selection, land preparation, fertilizing, sowing, field management, and rotation.
Abstract:
A system and method for optimizing chemigation of a crop. The method includes: identifying at least one image of at least one portion of the crop; analyzing, via machine imaging, the at least one image to identify at least one reference image respective of the crop; determining, based on the at least one reference image, at least one abnormality respective of the crop; and generating a chemical composition for treating the at least one abnormality.
Abstract:
A system and method for providing fertilizer for crop production in an aqueous solution comprising nano-sized fertilizer particles, which are free of any chemical side chain and free any micelle to protect the nano-sized particle from re-agglomeration, suspended therein for improved uptake by the population of the crop.
Abstract:
Disclosed herein are fertilizer compositions comprising: a fertilizer comprising a nitrogen compound, a phosphorus compound, and a potassium compound. The fertilizer composition also comprises a filler. Also, disclosed are the methods of making and methods of using the fertilizer compositions.
Abstract:
Fertilizer compositions for plant production are described, comprised of decontaminated manure and Bacillus spores, preferably a humic acid derived from lignite and, optionally, one or more of N compounds, P compounds, K compounds, and combinations of two or more of these compounds. Preferred compositions are those wherein the ingredients are blended into an admixture resulting in a granular product. Other preferred compositions are those blended into an admixture resulting in a powdered product. Preferably, the ingredients are formed into hardened prills or pellets. Processes for production and use are also presented.
Abstract:
A process for uniformly coating granular fertilizer formulations with one or more chelated metallic micronutrients which comprises the following steps: blending a granular fertilizer formulation in, for instance, a rotary drum mixer; spraying, while the blending continues 1 to 5% by weight of an aqueous solution or slurry containing one or more chelated metallic micronutrients, as for example, Na.sub.2 Zn EDTA, onto said fertilizer formulation; and adding, before or after said spraying, and while the blending continues 1 to 4% by weight of a finely divided water-absorbent additive, such as, a synthetic calcium silicate or finely divided silica, to the fertilizer formulation. The finished fertilizer formulation then contains 0.05 to 0.5% by weight of micronutrient.
