METHOD OF AUTUMN SOIL STRIP TILLAGE WITH VARIABLE-DEPTH SURFACE CULTIVATOR Russian patent published in 2009 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method involves boardless strip soil loosening. Flat loosening of even strips is done at a depth of 0.28-0.3 m, and odd strips - at a depth of 0.1-0.12 m. On moderately weed infested and moderately packed soil, strips are made with width of 0.3-0.4 m. On heavily weed infested and packed soil, even strips are made with width of 0.4 m, and odd strips with width of 0.6 m.

EFFECT: such a technique allows for reducing power input on autumn soil preparation and increases snow water intake of the soil.
