Abstract: On the basis of field research, the current state of soils in the eastern zone of the Republic of Kalmykia was studied.The predominant soil cover in this area is represented by brown saline soils and brown-desert soils in a complex with salt licks.The purpose of the study is to study the absorption complex, as well as the composition and content of exchangeable cations in the soils of the eastern zone of the Republic of Kalmykia.cations: calcium (Ca 2+ ) and magnesium (Mg 2+ ) and an assessment of the level of soil absorption capacity in 7 settlements of the Yashkul district of the Republic of Kalmykia.To conduct the research, 15 monitoring sites were placed on the borders and in the center of settlements, the background sample was taken at a distance of 500 m from the boundaries of the residential zone.The determination of the physical and chemical properties of the soils was carried out according to GOST and generally accepted methods.The results of the study showed that the level of absorption capacity of soils in the study area ranges from low to medium.The absorbent complex is saturated with the cations Ca 2+ and Mg 2+, and the content of exchangeable Ca 2+ predominates over the content of Mg 2+ in the range of 2 to 4 times.
