    The article describes the natural soil conditions of Sedum hybridum L. and Sedum ewersii Ledeb—populations area based on the results of field and laboratory soil studies of soils. Soil types, morphological features, chemical composition, nutrient elements, amount of humus, absorbed bases and salt composition, and mechanical composition of soils are determined. The following soil types were identified during field studies: Kokzhailau Gorge (population 1) – chernozem, Turgeni Gorge (population 2) – chernozem, near Kastek River (population 3) – chestnut soil. The humus content in the 0-80 cm layer of chernozem (population 1) of Kokzhailiau gorge is very high, ranging from 5.55-12.81%, the reaction of the soil medium is within pH 7.10-7.40, i.e. CO2 content ranges from 0.16 to 0.34. On chernozems of Turgeni gorge (population 2) humus content in 0-60 cm layer is very high, within 5.90-20.88%, reaction of soil medium within pH 6.15-7.07, amount of CO2 within 0.21-0.34. On chestnut soils near the Kastek River (population 3), the humus content in the 0-73 cm layer was in the range of 1.57-6.92%, the pH ranged from 7.13-8.23, i.e. it was alkaline, the CO2 content was in the range of 0.16 - 0.34. The composition of salts in the chernozems of the Kokzhailau gorge: CO3 - not detected; HCO3- - 0,24- 0,48 ; Cl- – 0.04; CO4- – 0,12-0,92; Sa+ – 0,29-0,49; Mg 2+ – 0,20-0,98; Na+ – 0,05-0,06; To+ – 0,05-0,23; The amount of salts is 0.060-0.083%. It was found that the soils of all 3 populations are not saline, since the amount of salts does not exceed the salinity limit.

    BACKGROUND: The article presents the results of the study of ecological characteristics of soils of three populations on the territory of Karatau. The populations were located in different geographical points with differences in soil types, depth of horizons and content of chemical elements. The study evaluated the main soil parameters including humus content, pH, CO2, macro- and microelements, and salinity level. It was found that population-1 (mountain gray-brown soils) was characterized by the highest content of humus and mobile nitrogen, indicating better availability of nutrients to plants. population-2 (mountain southern serozems) has higher potassium content, which is favourable for plant growth. population-3 (mountain gray-brown soils) showed the lowest content of mobile phosphorus and copper compared to other populations. Analysis of heavy metal concentrations showed that zinc exceeded the maximum permissible concentration only in population-2. At the same time, soil salinization at all three sites remains at a low level and does not pose a threat to the ecosystem. These findings are ecologically significant as they reveal the critical role of soil fertility and contamination in supporting the distribution and survival of the rare endemic species Spiraeanthus schrenkianus. These results provide new information for assessing the fertility and sustainability of land resources.
