METHOD OF SUBSURFACE TILLAGE OF SLOPING LANDS Russian patent published in 2013 - IPC A01B79/02 A01B13/16 A01B35/16 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular, to soil erosion. In the process the beardless vertical para-ploughing is carried out to a depth of 0.3 m and a surface mulching of top soil to a depth of seeding. At that the soil preparation is carried out in two phases, in the first phase in the autumn in the soil the vertical slits are made with shovel-shaped working elements with a size of k×b×h₁ - respectively 0.05×0.3×0.3 m with a variable pitch S, which varies ranging from 0.1 to 0.3 m, with the placement of the slits in staggered order. Then, in spring the second phase is carried out by a solid surface loosening and mulching the soil with the tools with rotary working bodies to a depth of sowing seeds.

EFFECT: method enables to prevent water erosion, to accumulate a supply of water and to ensure optimal conditions for humus formation.
