METHOD FOR INCREASING SOIL FERTILITY Russian patent published in 2021 - IPC A01C21/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and can find application in arable farming when using straw and crop residues as sources of mineral nutrition of agricultural crops. The method includes the processing crop residues with a destructor solution, embedding the treated crop residues into the soil, sowing a sideral crop and rolling crops. During the harvesting period, the straw is crushed and evenly scattered over the surface of the field by combine harvesters. In one pass, the machine-tractor unit sequentially processes plant residues with an aqueous solution of biological destructors, introduces nitrogen mineral fertilizers, seals the treated plant residues into the surface layer of the soil, seeds the sideral culture and rolls crops. When the sideral culture reaches the optimal vegetative mass, it is embedded in the soil.

EFFECT: method makes it possible to increase soil fertility and reduce costs.
