Kashin V.K., Ubugunov L.L. MICROELEMENTAL COMPOSITION OF SOILS AND STEPPE PHYTOCENOSES OF THE WESTERN TRANSBAIkAL REGION // Arid ecosystems. 2020. V. 26. № 2 (83). P. 86-95. | PDF
The average content and variation of 17 microelements in Kastanozems and vegetation of Western Transbaikalia steppe ecosystems have been determined. According to the rate of accumulation by steppe plants, Mo, Zn, B, Cu are classified as elements of high uptake; Li, and Mn are elements of medium uptake; and Be, Al, Ti, V, Cr, Fe, Co, Ni, Zn, Ba, and Pb are elements of low uptake. Correlation between the contents of microelements in plants and soil have been found for V, Cr, Mn, Fe, Zn, Ba, and Pb (r = 0.51–0.82). Deficit of Zn, Cu, and B and elevated contents Fe, Mo, Ba, and Sr have been revealed.
Keywords: microelements, steppe vegetation, coefficients of biological absorption, Western Transbaikalia.
