(54) METHOD OF TREATMENT OF THE FERTILITY OF SOIL ON SLOPES BEFORE LANDING OF AGRICULTURAL CULTURES

The invention relates to agriculture, in particular to methods for applying organic fertilizers to the soil on slopes.

There is a method of increasing soil fertility on the slopes before planting agricultural crops, including cutting trenches with zero slope, fit into the terrain, and making them organic fertilizers l.

The disadvantage of this method is the impossibility of applying large doses of liquid organic fertilizers and loss of arable land.

The chain of the invention is to increase the efficiency of the process due to more complete utilization of liquid organic fertilizers.

The goal is achieved in order to improve soil fertility on the slopes before planting agricultural crops in a manner that includes cutting trenches with a zero slope.

blended with organic fertilizers, trenching is done during the non-growing season, and liquid organic fertilizer is applied repeatedly, and the trenches are leveled before planting agricultural crops. In addition, the cutting of trenches is carried out annually, each time the zone is shifted

to cut at least the width of the trenches.

FIG. 1 shows the layout of trenches on slopes using this method, on

15 of FIG. 2 - field before planting agricultural crops after leveling trenches using this method; in fig. 3 - the same, using a known method

20 (prototype).

During the non-vegetation period, i.e. after harvest, trenches 1 with zero are cut on the hillsides

slope along the previously prograded track, located between two adjacent open irrigators 2 for their entire length.

For rainfed gray soils of the southern zone, a trench depth of 70-80 cm is recommended, the width on top is 100 cm, and the distance between them is about 5 m. The maximum number of trenches between adjacent irrigators does not exceed 15-20 pieces.

Adjacent trenches are connected along the slope by small grooves, the bottom of which is covered with plastic wrap to prevent erosion.

Trench filling with liquid manure starts from the upper trench. After that, the manure is transferred to the next trench, etc. Having filled manure with trenches between two adjacent irrigators, they switch to filling in other trenches of adjacent adjacent irrigators.

Since the liquid manure consists of two fractions — a liquid, in which organic salts are dissolved, and a solid, the liquid fraction is absorbed into the soil, and it is firmly deposited on the bottom and slopes of the trench.

When multiple trenches are filled with liquid manure, they are completely or partially filled with solid fraction, i.e. manure. Due to the liquid fraction (slurry), moisture accumulation occurs in the soil and subsurface layers (moisture reservoir to a considerable depth).

In the spring before plowing, the trenches are filled with a bulldozer, the soil is evaporated by a motor grader, and after plowing they are planted with annual tilled feed crops.

During the growing season, open local sprinklers are used for their intended purpose. Liquid manure diluted with water using irrigation machines irrigates fodder crops.

 In the autumn, after harvesting, trenches are again cut into these fields, and the cutting zone is shifted by no less than the width of the trench.

5 All these operations are repeated annually, and after a few years, the plots of field 5 processed :: 1e by this method almost completely change their structure.

0 Through the use of this method, the loss of arable land is eliminated, the yield of agricultural crops is increased due to a large charge of organic fertilizer 5 of scientific research institutes and pre-arable soil moisture supply, and a transformation of the soil structure is achieved.

Claims (2)

1. A method of increasing soil fertility on the slopes before planting agricultural crops, including cutting trenches with zero slope, fit into the terrain, and the introduction of organic fertilizers in them, contributing to the fact that, in order to increase its efficiency due to more complete utilization of liquid organic fertilizers, trenching is done during the non-growing season, and repeatedly, and before planting agricultural crops, trenches were leveled. 2. Method POP1, characterized in that the cutting of trenches is made annually, each time shearing the cutting zone by not less than the width of the trenches.
