Geochemical assessment of soils of the forest-steppe zone of the South Urals

Average parameters of the maintenance of microelements in soils are presented and the concentration of klark (CK) showing deviations from the average maintenance of chemical elements in a lithosphere, and also coefficients the concentration (Кс) characterizing excess of the maintenance of chemical elements in a point of approbation over its average contents on a background site of a forest-steppe zone of the South Urals are calculated.
