摘要

The contamination of heavy loamy chernozem by iron, sodium, magnesium, calcium, and hydrogen chlorides (2% of soil mass) decreases soil moisture content (W, percent of soil mass) in the interval of the soil moisture pressure (P) from 0.0 to —0.6 atm,which indicate soil degradation. In a range of /"from —0.2 to —0.6 atm, there is a close correlation between the logarithm of P module (logl/3!) and l-Kand, therefore, a regression relationship log|/>H^ = — kW, where |/*0| and k are empirically determined parameters. This relationship is similar to the Landau—Deryagin law. The parameters and k are also in a close correlation, which is described by the regression equation |/g| = 29.3A: — 0.557. At chernozem contamination by chlorides, the and k parameters become smaller, and so they may be used for the evaluation of degradation of chloride-contaminated soils.
