M. : Intellect, 1996. — 168 s. The functioning of irrigated soil is considered in the interaction of the time process and the spatial form (micro-,). For the first time, the transformation of the soils of Russia under the influence of irrigation is fully shown, depending on the emerging situations in automorphic and hydromorphic conditions. with different water quality, at different mineralization and level of groundwater occurrence and degree of drainage of the territory In addition, The direction of soil transformation is revealed as a result of the application of various measures of their restoration. Assessment criteria for five classes of ecological condition of irrigated soils of Russia on 19% of the area are overmoistened, 14% salted, In large areas, erosion is observed, loss of humus, carbonates, Physical properties are deteriorating almost everywhere , compaction (rarely fusion), Deterioration of soil structure . In the first stages, these processes are quickly fixed at the micro-level in the arable horizon, then they appear at the macro-level in the arable horizon and in the mesostructured units of the lower horizons and gradually spread to the entire soil thickness. The main processes of soil degradation during irrigation are identified and soil restoration measures are developed. Ecological state of irrigated soils of Russia. Objects and methods of research .
