METHOD OF DEEP SOIL TREATMENT, IN WHICH PLOUGH PAN IS FORMED Russian patent published in 2025 - IPC A01C21/00 A01B79/02 

FIELD: agriculture.

SUBSTANCE: method for deep treatment of soil, in which a plough pan is formed, consists in the fact that during the harvesting period the straw is crushed and evenly scattered on the field surface with a combine harvester. In one pass with machine-tractor aggregate straw and crop residues are sequentially treated with solution of biopreparations-decomposers, if necessary, based on presence of nitrogen in soil, nitrogen mineral fertilizers are applied, fertilizers, straw and stubble remains are embedded into soil, green manure crops are sown and crops are rolled. After 1.0-1.5 months, when the green manure crop reaches its optimum vegetation mass, it is embedded into the soil. On soils in which a plough pan is formed, after the vegetative mass regrowth, the green manure crop is embedded into the upper soil layer up to 10 cm, keeping it intact, deep soil treatment is carried out chisel ploughs to depth of up to 40 cm with destruction of plough pan.

EFFECT: invention provides for increased soil fertility, creation of favourable conditions for growth and development of plants, which makes it possible to increase crop capacity.
