The article provides modern researches of the solonetz complexes soils on the example of the Kochubey bio-sphere station of the Daghestan Federal Research Centre of RAS. Geographically the station is located in the central part of the Terek-Kuma Lowland and within the territorial borders of the administrative boundaries in the eastern part of the Nogai region. The distinctive feature of the soil mantle of the North-Western Caspian region in the part of the Terek-Kuma lowland is considered to be the distribution of soil varieties according to the degree of salinization of light-chestnut, light loamy, and sandy-loam soils in complexes and combinations with solonetz soils, as well as with solonetz-solonchak and solonchak separated by sandy massifs. Studying the current state of the salt balance of the solonetz complexes under conditions of the arid climate, decrease in the level of the Caspian Sea against the backdrop of global climate warming is an important objective in studying the patterns of development of the solonetz process in the soils of the dry steppe zone. The soils of the solonetz complexes of the Terek-Kuma lowland are poorly studied although medium-scale mapping has revealed large tracts of these soils. The soils occupy flat depressions and have a well-defined solonetz profile. As a consequence of the studies of the semi terrestrial soils, characteristics of genetic horizons are given. The content of forms of exchangeable bases in the solonetz complexes soils and their relationship with morphological characteristics has been established.
