METHOD FOR INCREASING FERTILITY AND DEEP TREATMENT OF SOIL WITH HEAVY MECHANICAL COMPOSITION Russian patent published in 2025 - IPC A01C21/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: in the method, straw is crushed and evenly scattered over the surface of the field by a combine harvester. In one pass, the machine-tractor unit performs successive treatment of plant residues with an aqueous solution of biopreparations-destructors and embedding the treated crop residues into the soil. Green manure crops are sown and sowings are rolled, if necessary, nitrogen mineral fertilizers are applied. When the green manure crop reaches the optimum vegetation mass, it is embedded in the soil. On heavy soils, after growth of vegetative mass, green manure culture is embedded in upper soil layer up to 10 cm. Deep cultivation of soil is carried out with flat-cutters-subsoilers to depth of 22-27 cm.

EFFECT: method provides the planned yield with the specified quality parameters, increased soil fertility due to the completion of the decomposition process of stubble-root residues and the vegetative mass of green manure in the soil in aerobic conditions, elimination of habitat of pathogens and diseases in autumn-spring period.
