METHOD FOR DEEP LOOSENING OF DRAINED LANDS Russian patent published in 2023 - IPC A01B79/02 E02B11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method provides for working passages of the ripper across the direction of the tubular drainage. On drained lands, drained areas of tubular drainage are delineated with a width of 3 to 4 depths of tubular drains. Across the direction of the tubular drainage, working passages with a depth of up to 75 cm are performed with a ripper. At the moment of the working passage of ripper within the allocated pre-drained areas, finely dispersed, with a particle size of 0.01 to 0.05 mm, copper pyrite powder is fed into the cavity trace of the ripper share passage in the norm from 20 to 45 g/m.

EFFECT: providing an increase in the water permeability of the soil-ground layer and an acceleration of the removal of excess water by reducing the intensity of tubular drainage ochretization.
