(54) METHOD OF ANTI-EROSING TREATMENT

POCHVB1

one

The invention relates to agriculture, in particular to the protection of soil from erosion, and can be used to increase snow accumulation in the forest and to prevent the development of water and wind erosion processes.

The known method of anti-erosion treatment of the soil is carried out by means of which the pulling is performed with a turn of the reservoir by 100-110 ° to form a water-absorbing slit at the junction of the layers, and the cutting of the scenes is carried out by partially removing the stubble sandwiched between the layers from the water-absorbing slit 1.

The disadvantage of this method is that it does not allow creating scenes at full height of the stubble, the main mass of which is sandwiched between soil strata, and only a small part of it acts on the soil surface. In addition, plowing the soil at 100 ° C (100 ° –110 °) promotes strong drainage (drainage of plowed and subsurface soil horizons, which is extremely undesirable under conditions of insufficient and unstable moisture.

Also known is a plowing method, in which, in order to preserve stubble, on the surface, the undercut layer is horizontally divided into two unequal parts, the lower major part is wrapped in an open furrow and the upper part of stubble is cut up on it 2.

The disadvantage of this method is that snow accumulation is limited by the level of the height of the stubble, therefore, maximum retention of snow falling on the floor surface is not ensured. In addition, the absence of anti-erosion nanorelief (holes, intermittent furrows) on plowing does not contribute to the retention of melt water and to prevent erosion on soils located on slopes.

The purpose of the invention is to increase snow accumulation on the pelt and prevent the occurrence of water and wind erosion processes in the soil.

To do this, cut the soil layer horizontally into two unequal parts, wrap the lower most part of the reservoir into the open furrow and place the cut upper part of the stubble up on a bare top, before dividing the reservoir horizontally adjacent to the right, the soil layer is cut to half the plowing depth.
