SU946419A1 - Method of slotting agricultural areas - Google Patents

Description

The invention relates to agriculture, in particular to methods of anti-erosion protection of the soil.

There is a method for making soil on winter wheat crops across a slope to a depth of 35 cm or more using for this purpose cleft, Lobova is relatively (2-2.5 cm) for the working posts of the working bodies, which makes it possible to cut narrow helium without large soil spreading and plant damage C1b

However, the smooth surface of the working body forms compacted waterproof walls. When the soil moisture is 22%, rashes form in the upper layer of the wall of the slit, which leads to their rapid degradation and closure after the ingress of moss precipitates.

There is also a known method of slitting the soil on crops .rjjx, pasture and perennial grass grasses on the slopes, which consists in the fact that, simultaneously with the aiming of water, the water canal, SECH; v floor t2 ,, /

The disadvantage of this method is the shedding of the walls and the fast swimming gap as they are wetted by moisture precipitation, low permeability and water absorption, i-fenb quickly goes down.

The purpose of the invention is to extend the service life.

ten

The goal is achieved by cutting the slit with simultaneous deep loosening at its base, the walls of the upper half of the slit are rolled, rounding the input

15 corners, and on the compacted bottom lay loose soil.
