Nevertheless, the lower horizon of the parent rock is not saline and is not the source of origin of soil profile salinization. Soil texture is heterogenic. There is an interchanging of light and medium loam on horizons, then transition to sandy loam (Table 3). Soil profile cut 08O meadowy xeromorphic alkaline medium loam based on gravel (43 deg1'26.56''79''14'30.53'' H = 1823 m), and TKS is absent. The terrace of the Kegen River is up 150 m above the soil profile of the TKS \"Saryzhaz\" population on the floodplain (Figure 7). The vegetation includes _Actnatherum_[32] and _Carex_[28]. Depth 50 cm. The humus-accumulated horizon (A + B) = 40 cm. Effervescence from HCl-surface. Salts--none are visible. The upper soddy horizon (A\({}_{1}\)\({}^{8}\) = 0-5 cm) is gray, dry, dusty, radiculose, medium loam, and dusty-lumpy. (AB = 5-15 cm) is gray, dry, compacted, radiculose, lumpy-powdery, clay 1 (B\({}_{1}\) = 15-30 cm) light gray, dry, dusty-platy, clay loam. Horizon (B\({}^{1}\) = 30-40 is dark gray, dry, dense, gruffly lumpy, clay loam. Horizon (CD = 40-50 cm) is gravel with a moderate quantity of fine earth. In the upper horizon, the content of humus is 5.5%; with depth, it decreases up to 0.8%, and total nitrogen is 0.4% (Table 1). The CO\({}_{2}\) content is increased with depth from 6.7% to 11.1% in the carbonate horizon. The accumulation of absorbed alkali in the upper soil horizons is 20.95-31.13 mg-eq. per 100 g of soil. The quantitative composition of absorbed alkali varies widely by horizon, but exchangeable Ca\({}^{2+}\) dominates in all horizons (10-73% of the total). The involvement of Mg\({}^{2+}\) in the absorbing complex is significant (21-75% of the total). The soil solution reaction is extremely strong alkaline (pH = 10.2-10.3). The content of easily hydrolyzed nitrogen is 126.0 mg/kg in the soddy horizon; with depth, it gradually declines up to 52.7 mg/kg in the carbonate horizon. The content of mobile phosphorus sharply reduced the profile from 70 to 3 mg/kg of soil. The content of exchangeable potassium in the upper horizons is 1000-950 mg/kg, with subsequent decreases up to 770 mg/kg. Figure 7: Landscape and soil profile cut 08O, 150 m from TKS population “Kegen”. The whole profile of meadowy xeromorphic alkaline medium loam soil is saline. Therefore, the soddy horizon is slightly saline (Table A2). The soil salinization increased to a very severe level, which was observed in the AB and B\({}_{1}\) horizons. In lower soil horizons, the soil is highly saline. The soil salinization type is chloride-sulfate and sodium. Soil texture is heterogenic. The soddy horizon is represented by light loam. The whole lower profile is clay loam (Table A3). Morphogenetic Features and Physicochemical Properties of the Studied Soils near the \"Tuzkol\" Salt Lake. Soil profile cut 06O TKS \"Tuzkol\" population. Meadowy alkaline clay loam soil based on sand (43\({}^{\circ}\)1\({}^{\prime}\)34.77\({}^{\prime\prime}\) 79\({}^{\circ}\)59\({}^{\prime}\)17.30\({}^{\prime\prime}\) H = 1962 m). Shore of Tuzkol Lake (Figure 8). Along the lake, a strip of alkaline soils above sedge vegetation with meadowy plantain (_Plantago_ L). Cut on the low side of the lake 30 m from the water. Vegetation: _Carex_[28], _Plantago salsa_[41], _Fenugreek_[40], and _Taraxacum_[31]. Projective cover 100%. Height 2-3 cm. Effervescence from HCl-surface. Salts 40-60 cm sparse fibers. Depth 90 cm. The humus-accumulated horizon (A + B) = 15 cm. The upper soddy horizon (A = 0-5 cm) is light grayish with rusty spots, freshly compacted, clay loam, and heavily lumpy. The lower soil horizon (B\({}_{1}\) = 5-15 cm) is brown with rusty spots and is freshly compacted, lumpy clay loam. The horizon (C\({}_{1}\) = 15-40 cm) is yellowish-brown, slightly humid, compacted, structureless, and clayey. (C\({}_{2}\) = 40-60 cm) is light-grained, humid, slightly compacted, indistinctly clumpy loamy sandy loam. (C\({}_{3}\) = 60-84 cm) is dark brown, humid, poorly compacted, fine-graded sand.
