METHOD OF STRIP DEEP TILLAGE AND TOOL FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC A01B79/02 A01B49/04 

FIELD: agriculture.

SUBSTANCE: method comprises cutting of slot, raking to the sides of field residues while simultaneous loosening at a predetermined width, fertiliser application to the controlled depth and compacting of the treated strip. Loosening is carried out to the desired depth with the restriction of zone of deformation expansion in the longitudinal and vertical plane to the width of the treatment. The tool comprises working sections mounted on the frame using the parallelogram mechanism. Each section comprises a height-adjustable chisel ripper with fertiliser guide. In front of the chisel ripper the central circular knife with flanged and a pair of disc cleaners are mounted. Behind the chisel ripper, a pair of circular knives and a compactor is mounted. A pair of height-adjustable circular knives is mounted at a depth with overlapping with its plane of the deformation zone from the chisel ripper. The width of arrangement of the pair of circular knives in cross-vertical plane is equal to the width of the treated strip.

EFFECT: reduction of energy consumptions and improvement of quality of soil treatment.
