METHOD FOR DECOMPRESSION OF SOIL COMPRESSED BY DRIVE SYSTEMS OF AGRICULTURAL TECHNIQUE Russian patent published in 2006 - IPC A01B37/00 

FIELD: agriculture, in particular decompression of soil compressed by drive systems of agricultural machines.

SUBSTANCE: method involves forming triangular furrows on soil layers during autumn plowing thereof; on plowing by means of plow having right-hand bodies, forming vertical left-hand wall and inclined right-hand wall of furrow, said inclined wall extending through right-hand upper corner of turned soil layer; providing apex of furrow profile extending through mid portion of boundary conventionally drawn within turned soil layer between compressed soil layer received and adapted to be decompressed and remaining portion of soil layer. Plowing process followed by cutting furrows is performed by means of tool comprising plow with right-hand bodies, with furrow cutters being positioned behind each of said plow bodies. Rain or thaw water penetrates into furrows to saturate, through inclined wall of furrows, three quarters of volume of soil layer of each soil layer turned during plowing process, said saturated three quarters of volume of soil layer being maximum compressed portion of soil.

EFFECT: increased efficiency in decompressing surface layer of soil by moistening with following freezing thereof.
