| Abstract: | Analytical solutions were given for the problem of dissolution and leaching of salts in waterlogged regions with deep and shallow water tables under surface salinization and with account for equilibrium sorption (characterized by a linear exchange isotherm) and the problem of nonequilibrium irreversible sorption (characterized by biological transformation in the soil solution, which follows the first-order kinetics). A method was developed for determining the hydrochemical parameters (mixing step and dissolution rate coefficient of solidphase salts) from the average salt contents of water-saturated soils of given thickness before and after leaching determined under laboratory and field conditions. |
