- Аннотация: The salt structure and structure of salt profiles of automorphic and hydromorphic soils of stony steppes on fallow land and arable land are studied. It is shown that during agricultural use of these soils the general maintenance of salts in a profile, including that in the root-inhabited layer, increases and the type of salt changes. In cation structures the quantity of Na+ and, to a lesser degree, of Ca2+, increase, and in the anion structure CO 3 2− increases. It is shown that the most significant transformation of the salt mode of soils during agricultural use is observed in soils with low humidity.
