摘要

Comprehensive studies of the properties and processes of nonirrigated soils at different hierarchical levels of their organization are carried out and regularities of their changes under the effect of irrigation are revealed. It is shown that irrigated soils of weakly drained landscapes compared with drained change more rapidly as a result of humidization, leading to acceleration and intensification of the mutual influence of processes at all levels of their organization. Positive and negative phenomena are noted under irrigation, the rate and extent of which depend on soil type, degree of drainage of the landscape, changes in the water regime and moisture content of the soils, quality of the irrigation water, and level of agrotechnologies.
