The present invention provides a special fertilizer for cut side slope soil remediation in high altitude areas, which is prepared by effectively compounding raw material components of a yak manure-containing compost, an organic micro multi-element fertilizer, a chemical fertilizer, attapulgite powder and sodium alginate under certain conditions. The special fertilizer has obvious effects on the aspects of improving the physicochemical properties of artificial soil at cut side slope wounds in the high altitude areas, increasing the fertilizer efficiency and promoting vegetation restoration.

A controlled release fertilizer has been prepared comprising a nutrient core coated with one or more moisture barrier coatings, at least one of said moisture barrier coatings comprising: at least one polyethylene wax; and a thermoset polyurethane from the reaction of a polyol and a polyisocyanate. The weight ratio of thermoset polyurethane to polyethylene wax is from about 50:50 to about 98:2. The polyethylene wax is heated above the melt point of the polyethylene wax and mixed and dispersed into the polyol component of the thermoset polyurethane in a ratio of 90-70% polyol to 10-30% polyethylene wax before the thermoset polyurethane-forming mixture is applied to the surface of the nutrient core and cured. A coating of a high temperature microcrystalline wax can be applied prior to final curing of the thermoset polyurethane to the coated nutrient core particles.

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.

A method of forming a pelletized fertilizer includes combining a fertilizer material with an organic binder to form a wet mixture, and drying the wet mixture to form particles comprising the fertilizer material and the organic binder dispersed therein. The fertilizer material includes solid particles of langbeinite, and the organic binder includes at least one cellulose polymer in a solid phase or a liquid gel phase. The dried particles are coated with mineral oil to form coated particles. A pelletized fertilizer includes pellets comprising solid particles of langbeinite (and optionally, other fertilizer materials) interspersed with at least one cellulose polymer. A mineral oil coating is over the pellets.

A combined organomineral NPKSi-humate fertilizer having at least one particulate mineral NPK fertilizer is provided, which has at least one nutrient compound of nitrogen, phosphorous or potassium; and a particulate humic substance based silicon fertilizer, having chelates of monosilicic acid-humate compounds. The application also relates to a method of production of the combined organomineral NPKSi-humate fertilizer.

Plant fertilizer compositions, products, systems, kits, and methods. Products and methods for increasing the amount of soluble phosphorus in soil, solubilizing or increasing the level of soluble phosphorus and/or bioavailability of phosphorus in soil.

Methods and related systems for conditioning of granular fertilizers post-manufacture to reduce the generation of dust during handling, transport, and storage of the fertilizers, and/or to increase the agricultural benefits of the fertilizer. The method includes introducing a quantity of an aqueous conditioning agent, such as by spraying, to a plurality of fertilizer granules. The aqueous conditioning agent can include one or more beneficial agricultural and/or dedusting additives including one or more acidifying agents, one or more drying agents, one or more herbicides and/or pesticides, one or more chelating agents, one or more biological agents, and combinations thereof.
