- Аннотация: The contamination of heavy loamy chernozem by iron, sodium, magnesium, calcium, and hydrogen chlorides (2% of soil mass) decreases soil moistening (W, percent of soil mass) in the interval of the soil moisture pressure (Р) from 0.0 to –0.6 atm, which indicate soil degradation. In a range of P from –0.2 to –0.6 atm, there is a close correlation between the logarithm of Р module (log|P|) and W and, therefore, a regression dependence log|PW| = |P0| – kW, where |P0| and k are empirically determined parameters. This correlation is similar to the Landau–Deryagin law. The parameters |P0| and k are also in a close correlation, which is described by the regression equation |P0| = 29.3k – 0.557. At chernozem contamination by chlorides, the |P0| and k parameters become smaller, and so they may be used for the indication of degradation of chloride-contaminated soils.
