Description

one

The invention relates to agriculture and can be used to combat soil erosion, for example, on slopes.

There is a method of combating soil erosion, including the main anti-erosion treatment of the soil and cutting furrows across the slope with the introduction of organic filler. At the same time, the effectiveness of the retention of surface runoff is insufficient.

The purpose of the invention is to ensure the effective retention of surface runoff. This is achieved by the fact that during the main anti-erosion treatment of the soil, the top soil layer is cut off together with the stubble, formed into a tape and laid into grooves with the tape elevated above the soil surface.

FIG. 1 shows the plot nol, processed by the proposed method, a view in plan; in fig. 2 is a section along A-A in FIG. one.

Tape 1, formed from stubble and other plant debris, is laid in the furrows with elevation above the soil surface, and this tape is formed by cutting the upper soil layer together with the stubble and is embedded adjacent to it, the soil in the furrow. The entire cultivated area is covered with such ribbons, and between them there are strips of arable land 2, free from stubble. At the bottom of the furrows, slits 3 with a cut are cut, 2

4. Thus, the subsoil horizon of the soil 5, located below the bottom of the furrow, has been deeply punctured.

The stern collected into a tape and partially filled with a furrow acts as a draining material, eliminates the cracks and significantly increases the water permeability of arable land. At the same time, part of the stubble, the floor (soil) protruding above the surface

contributes to the uniform distribution of snow, reducing the freezing of the soil and preventing the occurrence of wind and water erosion of the soil, as it serves as an obstacle to the surface flow of rain or storm water and ensures the retention of solid runoff.
