METHOD FOR GREEN MANURING OF TOXIC SOILS IN CROP ROTATION Russian patent published in 2017 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: sowing green manure crops at different times and ploughing their biomass. After the harvesting of winter crops, bioconversion of crop residues is carried out by irrigation with the 0.1% aqueous solution of potassium humate with the subsequent incorporation into the soil. Wide-row sowing of annual Shabdar clover is carried out. After 30-40 days, winter Camelina is sown into interrows. The following year, in spring, both crops are mown and covered by a layer of the mixture of alanite clay and poultry manure at a ratio of 4:1. Sowing the next crop in crop rotation is carried out.

EFFECT: increasing soil fertility in crop rotation, reducing the fertilizers costs and increasing their efficiency, reducing the level of soil contamination with heavy metals.
