Influence of water supply methods of water-physical properties of soil in terms of arid conditions of South-East Kazakhstan

This article provides data on soil moisture and density, depending on the test options for water-saving technologies. The effectiveness of the «Aqusorb» hydrogel in regulating the water holding capacity of soils and improving its structure, which directly affects the growth and development of plants, has been shown. The best supply of soil moisture was noted in the options when the preparation was applied, 1.5 kg/m3 and 2.0 kg/m3. When using the preparation favorable water-air regime of soils appears, especially in critical periods for the development of plants. The purpose of the research was the scientific justification for the use of the «Aquasorb» hydrogel to improve the water-physical properties of the soil, which will directly contribute to the development of consumer and decorative gardening in the arid regions of southeast Kazakhstan. Experiments on the study of the water-physical properties of soils were performed according to generally accepted methods.
