Abstract

The paper studiessalinization of soils in the areas of the Syrdarya region as a result of influence human economic activities. The peculiarities of salinization problems, which was an integral part of land degradation, are considered.In general, the authors in the article "salinization of soils"are considered as a decrease or loss of biological and economic productivity of irrigated lands or areas under the influence of natural and anthropogenic factors. The object of the study was the irrigated territories of the Hungry Steppe belonging to the Syrdarya region,were there is a significant rise in groundwater of 1.5-3m and more, compared with natural conditions since 1960, 5.0-10m. The purpose of the research is aimed at studying the geotechnical properties and state of irrigated soils and grounds, taking into account natural conditions and influenceof anthropogenic factors. The degradation of soils of the Hungry Steppe is currently caused by: depletion of the surface soil layer due to wind and water erosion; changes in the chemical composition of the soil and biological environment caused by salinization oxidation and rarely pollution; accelerated loss of nutrients obtained from mineral and organic substances of the soil and the loss of the organic matter itself; compaction and loosening of the soil in connection with the development of infrastructure and housing. The geotechnical properties of the irrigated areas of the Syrdarya region - mainly salinized to varying degrees by weak, medium, and sometimes strong salinization. The ameliorative well-being of irrigated lands in the irrigated part of the study area is unstable, i.e. on these lands, groundwater remains moderately (3–10 g/l) and strongly (> 10 g/l) mineralized.
