Study of the chemical composition of soil in the natural-technogenic territory Aidarken

The article presents the results of an analysis of the content of microelements in the soils of the biogeochemical territory of Aidarken. Soil samples for analysis were taken from the top layer of soil cover (0-20 cm) at 3 points in the study area. Chemical analyzes for fertility elements (gross content of nitrogen, phosphorus and potassium, humus, absorption capacity, carbonate content, pH) and analysis for mechanical composition were carried out in the laboratory of the Republican Soil-Agrochemical Station of the Kyrgyzgiprozem State Research Institute under the Ministry of Agriculture and Mineral Resources of the Kyrgyz Republic. The soils of the studied areas belong to the following types: dark Turanian gray soils and mountain brown dry-steppe soils. Antimony, as an accompanying element of mercury, is above the maximum permissible concentration in all areas of the soil cover. High concentrations of individual heavy metals (Pb, Cu, Zn) were found in the tailings area.
