摘要：
FIELD: agriculture.SUBSTANCE: method includes soil drying by a closed header with rarefied parallel drains and a double-slope profile of soil surface between them. The profile of soil surface is developed by means of multiple ploughing into a plow ridge by inclosures with width equal to the distance between drains, and with formation of split furrows placed in the same vertical plane with drains. In process of ploughing a double-slope profile is also given with an inclination of less than 0.01 of the horizontal surface of the low-water-permeable subsurface horizon - a ploughing foot of subsurface. The double-slope profile of the subsurface horizon is developed by tilling soil of the subsurface horizon with increased thickness of the tilled later from the plow ridge to a split furrow and subsequent ploughing to the tilled topsoil. Previously prior to tilling, two increasing doses of lime, phosphorite flour, organic and mineral fertilisers are added from the plow ridge to the split furrow, which are assigned with account of growing thickness of tilled and ploughed topsoil of the subsurface horizon.EFFECT: such technology will make it possible to speed up drainage of surface waters and gravitation of upgrade water from topsoil, to level fertility of topsoil between drains, to develop a thick fertile topsoil and to increase capacity of crops grown on drained heavy low-water-permeable soils.2 cl, 1 dwgСпособ включает осушение почвы закрытым коллектором с разреженными параллельными дренами и двускатным профилем поверхности почвы между ними. Профиль поверхности почвы создают путем многократной вспашки в свал загонами шириной, равной расстоянию между дренами, и образованием разъемных борозд, размещаемых в одной вертикальной плоскости с дренами. При вспашке также придают двускатный профиль с уклоном не менее 0,01 горизонтальной поверхности слабоводопроницаемого подпахотного горизонта - плужной подошве пахотного слоя. Двускатный профиль подпахотного горизонта создают посредст
