(54) METHOD FOR TREATING SALTED SOILS

(57) The invention relates to agriculture. The purpose of the invention is to increase

efficiency of processing sodic soils in climatic regions with insufficient precipitation. For this, the humus layer of the soil, when it is raised and loosened, is simultaneously displaced on either side of the treatment zone with the formation of shoulders. The leveling of the surface layer of the soil over the treatment zone is carried out by shifting the shoulders into this zone after chemical substitution reactions in the lower layers of the soil. The ameliorant is introduced into the sodic layer with simultaneous mixing. The method provides an accelerated course of chemical-desalination reactions. 3 il.

The invention relates to agriculture, in particular to methods for treating alkaline soils with the introduction of chemical ameliorants.

The purpose of the invention is to increase the processing efficiency of sodic soils in climatic zones with insufficient precipitation,

The method of processing sodic soils consists in that the surface humus layer A is lifted, loosened and simultaneously shifted into soil piles in the treatment zone, and a chemical meliorant is introduced into the exposed sodic layer B, thoroughly mixed together, while the saline soil layer is loosened by cutting gaps in it. After the chemical reactions take place in the sodic layer, the loss of its toxicity and adverse physicomechanical properties, as well as the improvement of fertility and the penetration of decomposition products into the subsalled (carbonate) layer C through the loosened slits, soil piles of the humus layer A are shifted and evenly aligned along the surface of the zone processing.

The soil treated in this way is maintained for one growing season (1 year), sufficient for the desalinization of the alkaline layer, when the exposed alkaline layer, carefully crushed and

mixed with Himmeliorant, is under the intense influence of even the minimum amount of precipitation, solar radiation, temperature difference, which contributes to the accelerated chemical reactions on the salinity of the alkaline layer. Formed soil pads contribute to better snow and moisture accumulation, which is especially important when reclaiming alkaline soils to ensure the flow of chemical reactions and washing decay products from the core.

The tool consists of a frame 1, a hinge 2, a two-tailing device 3 for treating a surface humus layer, a tank 4 with a chemical meliorant and a pipeline 5 for introducing a chemical meliorant, a milling cutter 6 for treating saline layer B and rippers 7.

When this gun is operated, a double-boom device 3 cuts layer A and shifts it into piles, chemical meliorant from tank 4 through pipeline lines 5 is applied to the surface of alkaline layer B, mill 6 intensively crushes solonts layer B, mixes it with chemical meliorant (X M), rippers 7 cut gaps in the subsollen layer, through which decomposition products of a chemical reaction leak from the core

the uninhabited layer in the underlying layers for their final neutralization.

After completion of the layer B rassolonting, the tool treats with the middle part of the two-dump device 3 soil piles consisting of a fertile humus layer, which is evenly distributed over the surface.

Claims (1)

The method of treating saline soils, which consists in lifting and loosening the humus layer in a technological sequence, introducing ameliorant into the solonetz soil layer while simultaneously mixing them, loosening the solontsy soil layer by cutting gaps in it, and leveling the surface humus layer of soil in the treatment zone, characterized in that, in order to increase the efficiency of treatment of sodic soils in climatic regions with an insufficient amount of atmosphere When the soil is lifted and loosened, the humus layer of the soil sediments is simultaneously shifted on both sides of the treatment zone to form shoulders, while the surface humus layer of the soil is smoothed out when the shoulders move to the treatment zone after chemical substitution reactions in the lower soil layers. well V XXNNNXNN XB + X.M.
