CURRENT STATE OF THE SOIL IN THE AREA OF DISTRIBUTION OF THE COENOPOPULATION OF ADONIS TIANSCHANICA LIPCH (ADOLF) 1 LLP «U.U.Uspanov Kazakh Research Institute of Soil Science and Agrochemistry», 050060, Almaty, al-Farabi Avenue, 75B, Kazakhstan, e-mail: qulymbet.qanat@gmail.com 2 Kazakh National University named after al-Farabi, Almaty, al-Farabi 71,Kazakhstan 3 University of Debrecen, Debrecen, 4032, Hungary The article describes the current state of the soil cover of the Kegen and Terskey Alatau passes. In addition, the morphological, chemical, physical and physico-chemical properties of soils were studied. Soil types were determined in two regions: slightly leached сhernozem in the mountain-steppe zone (Kegen pass); southern сhernozem in the mountain-steppe zone (Terskei Alatau). The humus content in the soil of both territories (layer 0-10 cm) belongs to the category of high level (up to 9.13 %). The pH value in the soils in two samples is alkaline, the upper hori- zons are slightly alkaline, and depending on the lower ones - medium-alkaline and highly alka- line, which range from 7.1 to 8.4. Both samples are characterized by high potassium level. The soil samples of Terskei Alatau, there is a relatively high level of nutrients. More than 25 plant spe- cies were identified in the studied territories. The dominant species among them are Artemisia glauca, Artemisia vulgaris, Festuca valesiaca, Dracocephalum integrifolium. Early mapping data was used during the research to produce a new soil map with updated data. Key words: soil cover, horizons, plant species, morphological descriptions, Kegen pass, Terskey Alatau, soil moisture, soil types. |
