МИКРОСТРОЕНИЕ ЦЕЛИННЫХ И РАСПАХАННЫХ ПРЕДГОРНЫХ СЕРОЗЕМОВ ОБЫКНОВЕННЫХ СЕВЕРНЫХ ЮГО-ВОСТОКА КАЗАХСТАНА

Abstract

The article gives the characteristics of northern ordinary virgin and cultivated foothill gray soils. It is set those microbiological processes, which lead to complete mineralization, have the primary value in the resolution of vegetative remains. It is noted the low presence of humus, high porosity, micro-aggregation, carbonation of the whole soil profile, the presence of gypsum in a parent rock. There is a formation of optically oriented gypsum by the inner soil weathering and argillization of primary minerals influenced by the process of soil formation; also it is shown the difference in age of humus. It is identified that in the result of long-time gray soils plowing the sigh of degradation appears in arable layer; there is a lack of humus in the soil, the anthropogenic "lessivage" and the structural changers of pore space are observed.
