The analysis of the influence of hydrologic fields on soil cover structure provides an important theoretical basis for the study of soil genesis and agroproductive properties. Without such analysis, it is almost impossible to create a realistic model of soil natural fertility, to work out the strategy of soil reclamation, and to optimize the regimes of soil functioning. To carry out meliorative measures and to develop technologies of agrocenosis formation, it is necessary to take into account the regularities of soil cover structure in connection with soil hydrology.
