METHOD OF STEPPED TILLAGE Russian patent published in 2012 - IPC A01B79/00 A01B13/14 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in processing of soil with plowing units. The method includes a consistent separation from the soil layers monolith of the upper and middle layers, their circulation and laying with a change in mutual position vertically, and also loosening the soil of the lower level. Laying of the soil stratum of the upper layer is carried out on top of the loosened soil stratum of the lower layer. After laying of the soil stratum of the upper layer, at the same time the soil of middle and lower layers are loosened, and then are separated, wrapped, and the soil stratum of the middle layer is laid on top of the previous soil stratum of the upper soil layer.

EFFECT: method enables to reduce energy costs for tillage due to eliminating of compaction effect on soil of the lower level of blades of plow bodies plowshares during separation of the soil stratum of the middle layer, and thereat forming a compacted soil layer, as well as its subsequent loosening; increases productivity of the device and reduces fuel consumption on soil tillage.
