MULTIFUNCTIONAL SOIL CONDITIONER, METHOD FOR ITS PREPARATION AND APPLICATION Russian patent published in 2021 - IPC C09K17/40 

FIELD: agriculture.

SUBSTANCE: soil conditioner includes the following percentages of raw materials: soil composite microbial agent 1-2%, fermentation product of solid agricultural waste 40-65%, organo-inorganic polymer water-retaining material 30-50%, the first auxiliary additive, which is solid agricultural waste rich in organic nitrogen 1-10%, the second auxiliary additive, which is a combination of organic phosphorus-rich agricultural organic waste and natural mineral powder 1-5%, the third auxiliary additive, representing solid agricultural waste from biological sources, rich in potassium nutrients 1-15% and a fourth auxiliary additive consisting of minor elements, trace elements and useful elements 1-5%. The soil composite microbial agent includes at least three of the phosphorus solubilizing bacteria, potassium solubilizing bacteria, nitrogen fixing bacteria. The fermentation product of solid agricultural waste is processed agricultural waste that is obtained through an aerobic composting process, and the processed agricultural waste includes at least one of palm residues, durian residues, coconut bran, bagasse, cassava residues, sheep manure, cow manure or rabbit manure. The organo-inorganic polymer water-retaining material is formed by copolymerization by melting an organic polymerization monomer and an inorganic raw material, wherein the organic polymerization monomer includes at least one acid selected from acrylic acid, malic acid, succinic acid or citric acid, and the inorganic raw material includes at least one compound selected from urea, MAP, potassium sulfate, ammonium polyphosphate, polyglutamic acid, polyaspartic acid or polyacrylamide.

EFFECT: proposed soil conditioner makes it possible to effectively increase the survival of crops at the seedling stage, effectively prevent diseases transmitted through the soil, significantly improve the quality of the product, and also ensures the restoration of saline soils.
