Abstract

The invention can be used in agriculture for fertilizing plants with livestock runoff (LS), including and not divided into fractions, as well as for the protection of nature. In order to reduce the environmental pollution, the filling of trenches made across the slope and connected by river beds with an arable horizon are carried out by layering the frosting layer, and the upper layer is frozen with clean water. In the process of ice sinking, the liquid fraction of JS enters the plow horizon through molehills, fertilizer plants. 1 hp f-ly, 2 ill.

Description

The invention relates to agricultural production and can be used in agriculture for the fertilization of plants with livestock waste water, not divided into tons, as well as for the protection of nature.

The purpose of the event is to reduce environmental pollution.

FIG. 1 shows an embodiment of the method, a plan view; in fig. 2 - the same, pa fe-t

Example. Transversely (slope 1, seeded with agricultural plants 2, approximately parallel to its horizontal, m), arrange trenches 3. The arable horizon and lower along the slope walls of the trenches 3 connect Kpuioviny 4, located in several (2 4) levels in height.

In the winter, livestock waste 5 is fed into the trenches;

By freezing, it reduces the filtration of runoff into the soil, since the first layer only plays the role of an anti-seepage screen. Vermesha layer (0.1 0.2m) of ice 6 in the trench is frozen with clean water

When snow is snowing, surface runoff passes over filled trenches. Moreover, a layer of ice from clear water prevents contact of frozen livestock waste and is surfaced, which prevents it from contaminating

Subsequently, the smoldering of livestock waste discharged in trenches occurs. Moreover, as they are this, the liquid fraction is drained by molehills into the arable horizon, fertilizer is spread, and the solid fraction is deposited over the smoked effluent, slowing down. The arrangement of the molehills in several rus ts

gradually, as they are, and evenly distribute it over the plowed land

Surface runoff generated during and after frozen drainage as a result of precipitation is intercepted by trenches and drained into the arable horizon by mole, which increases the availability of agricultural plants and prevents contamination of jelly / water plots and watercourses, as well as water erosion

The use of the proposed method has the following advantages. Livestock waste is reserved in winter, which allows to reduce the storage volume. Livestock waste is reserved directly on the field. There is no need for machines and emergency equipment for their long-haul farm soil surface runoff resulting from precipitation, which increases the moisture supply of agricultural plants and prevents contamination of -lying areas and watercourses, as well as soil erosion.
