A coating is applied in one or more layers on a granular material, such as a granular fertilizer material or the like. The coating may include a diisocyanate in either pure form or partially polymerized form, a polyol or polyol mix, and optionally a wax. The polyol or polyol mix may be, for example, a polyester polyol, a polyether polyol, or combinations thereof. In some examples, the polyol or polyol mix may be an aliphatic glycerine initiated polyether polyol, an aliphatic amine initiated trifunctional polyol, castor oil or castor oil derivative, or ethylene diamine that has been propoxylated or ethoxylated, and combinations thereof. The coating is reacted on the granular material.

The present invention relates to a liquid fertilizer composition and a preparation method thereof, comprising potassium silicate, a pH regulator, an emulsifier and a solvent, useful in the prevention and control of plant diseases caused by different pathogens.

There is provided herein a granule of potash and polyhalite comprising: at least 10% Potash; at least 10% Polyhalite; optionally a binder; and wherein said granule comprises a bulk density of at least 1 T/m.sup.3 and single strength of between 1-5 kg/granule.

Methods for producing solid acidic fertilizer granules, solid acidic fertilizer granules, and methods for their use in fertigation, are disclosed. The method can include providing a plant nutrient containing nitrogen (N), phosphorus (P) and optionally potassium (K), in a container; feeding an acid solution containing an inorganic acid into the container at a feeding rate comprising an average feed rate of 0.2 to 0.8 metric ton of the inorganic acid (MTacid) per hour per metric ton of the plant nutrient (MTnutrient) (MT acid.h−1.MT nutrient−1) and contacting the inorganic acid and the plant nutrient to obtain acidified granules with average moisture content of 0.5 wt. % to 1.0 wt. %; and drying the acidified granules to obtained dried acidic granules.

This invention relates to the art of fertilizers and, more particularly, to a coated granular fertilizer in which the dissolution rates of water-soluble fertilizer components are controlled by coating or encapsulating a granular fertilizer. The coating for the timed-release fertilizer is derived from plant cellulose extracted from hemp cellulose, sugar cane cellulose, or other plant-based cellulose.

The invention relates to an optimized nutrient salt composition comprising elemental sodium and potassium in the ratio of 1:1.5 to 1:7 preferably 1:3 and elemental potassium to chloride in the ratio of 1:1 to 1:1.5 and method of preparing the same. Said composition can be optionally added with a) salts of calcium and, or magnesium as taste stabilizers, b) carbohydrate like polysaccharide, oligosaccharide, disaccharide, monosaccharide to produce energy electrolyte powder, c) food additives selected from anti-caking agents, crystal modifying agents, flavoring agents, flavor modifying agents, coloring agents and or any other food additives and d) nutrients selected from proteins, amino acids, carbohydrates, sugars, fat/oil, fatty acids, vitamins, minerals and water. Said optimized nutrient salt composition can be used as food, food ingredient, food supplement, table salt, preservative, food additive, seasoning agent and ingredient for oral rehydration fluid, intravenous fluids, beverages, energy drinks, sports/study drinks and stimulant drinks for humans, pets and livestock and for plant nutrition.

A composition and method for producing an organic material with an inorganic coating. The inorganic coating may include ammonium sulfate. The present disclosure also provides a fertilizer having an inorganic coating. A method according to the present disclosure includes granulating an organic material and coating the organic material with a reactive coating composition. The inorganic coating material may be generated in situ to the process of coating the organic material.

The present invention discloses biomass compositions for improving shelf life, increasing fruit water retention, and/or decreasing needle-drop in conifer species and methods for making the same. The composition comprises pasteurized microalgae selected from Chlorella, Aurantiochytrium, Scenedesmus, or any combination thereof.
