The invention relates to agriculture and soil science, namely to methods of increasing vodoprochnost soil structure by soil application of different substances.

The known method of increasing vodoprochnost soil structure by adding petroleum bitumen [1]. He is in the tillage oil emulsion of bitumen.

The main disadvantage of this method is the necessity of making high doses petroleum bitumen - more than 10 t/ha

The known method of increasing vodoprochnost soil structure by adding peat adhesives [1]. He is getting alkaline extraction of peat, its neutralization and processing of this extract of the soil.

The main disadvantage of this method is the necessity of making high doses of peat adhesives - more than 10 t/ha

The known method of increasing vodoprochnost soil structure by making kilimov - products derived from methacrylic and acrylic acids [1].

The main disadvantage of this method is the necessity of making a sufficiently high doses of kilimov more than 500 kg/ha

The aim of the invention is to increase the efficiency of use of modifiers to improve the water resistance of soil structure and improving the performance of the method.

The technical essence of the invention lies in the fact that in the soil making m is defecator - monooleate of anhydromannitol, reinforcing microphase separation in supraliminal humus matrix that is responsible for photoproject soil structure.

The problem is solved in that in the method of increasing vodoprochnost soil structure, which consists in introducing into the soil modifier, modifier use monooleate of anhydromannitol.

The proposed method can significantly improve the efficiency of use of modifiers to improve vodoprochnost soil structure.

The following example reveals the essence of the proposed invention.

Example 1.

To determine the water-stability used air-dry aggregates of sod-podzolic soil with a size of 4.5-5.0 mm aggregates batcher was added to 10 μl of water. After that, the units were kept in a desiccator with a relative vapor pressure of water ~100% within 2 days. Then hydrated every unit added to 10 μl of a solution monooleate of anhydromannitol various dilutions and kept at 100% humidity for another day.

To determine vodoprochnost put soil aggregates into the cassette and a height of 6 mm, a cell diameter of 6 mm to the lower part of which was attached a wire diameter of 1 mm, which divides the cell in half and the supporting soil aggregates. The cartridge (square 8×8 with 64 cells) were placed in BONDAGE in the nnu, which was filled with water. Determination of water-stability was carried out according to the method Andrianova when exposed to the ultrasound system by calculating photoproject (waterproofness) Kachin [2].

The terms of the concentration of the modifier, expressed in mg/ml, at a flow rate in t/ha was performed, based on the weight of the studied aggregates, the concentration of the applied solution, the density of the soil 1,2 t/m3and the topsoil, water resistance patterns which provided a depth of 25 cm

Photoproject aggregates of soil was 88-90%.

The obtained results show that photoproject corresponding to the prototype occurs when making 15-20 kg/ha

By the well-known decision you need to make more than 500 kg/ha

Thus, the present invention allows to significantly improve the efficiency of the use of modifiers to improve vodoprochnost soil structure, reducing the necessary dose of application, thereby improving the performance of the method.
