SU913957A1 - Method of fighting soil erosion on slopes - Google Patents

Description

The invention relates to agriculture, in particular to anti-erosion measures.

There is a method of formation of anti-erosion rollers, which includes pouring across the slope of the rollers with subsequent sowing of the hard-core culture [1].

The disadvantage of this method is that the soil is poorly absorbed by the water flows, due to the fact that on the slope no anti-erosion plowing by the poles or deep gaps have been performed.

There is a method of intermittent tillage on the slopes, including the crafts of intermittent loosened furrows or slots, and bridges separating them may not reach the field surface (2].

The disadvantage of this method is that the soil loosened to different depths, having the same coefficient of loosening,

2

on the surface of the slope forms ridges of different heights and widths, namely, in deeply loosened areas, the ridges are higher and wider. As a result, the flow of water, ³ evenly distributed over the surface of the slope, accumulates in the narrow and low parts of the ridge, which leads to a breakthrough of the latter.

The purpose of the invention is to increase

^{, 0 the} effectiveness of anti-erosion work by artificial distribution of water flow over the surface of the slope.

¹⁵ The goal is achieved by the fact that sowing of a hardened culture is carried out over bridges and each subsequent uphill slope is sown shorter than the previous one, and in the following ²⁰ years the bridges form places displaced across the slope from the previous year's place at a distance equal to their length

planting last year's crops into the soil.

FIG. ι shows the plot of the field, processed by the proposed method, in plan; in fig. 2 - a section in a vertical plane.

The proposed method is as follows.

Intermittent plowing or slitting with or without jumpers on the surface of a slope is carried out across the slope. Next, a solid culture crop is planted above the bridges, with a number of plants sown longer than the web at the lower edge of the bridging, and each subsequent uphill slope is shorter than the previous one. As a result, the seeded area of the jumper takes the form of an isosceles triangle, whose sides may have a concavity. The flow of water falling on the length of the lintel, having encountered a plant barrier, will partially penetrate and be absorbed into it, and a significant part of it will be directed to the adjacent deep gaps or furrows. The following year, the preparation is carried out in the same way, only the jumper points should be placed across the slope in the direction of a distance equal to the length of the jumpers, and old crops when snapping or plowing are embedded in the soil.

The effectiveness of the invention lies in the fact that as a result of the artificial distribution of the flow of water over the surface of the slope, there is no need for multi-row fission or plowing. P result greatly accelerate the production of ₅ etsya anti-erosion works and greatly reduced their costs.
