We had investigated a question about influence of nonequilibrium phase transition ice-water (electrolyte solution on electrophysical and physico- chemical properties of water systems including homogeneous water electrolyte solutions and heterogeneous soil systems. To understand the complete set of physico-chemical phenomena on interface boundary ice-water electrolyte solution we had developed a special molecular model of nonequilibrium phase transition ice-water electrolyte solution. This model uses the conception of orientational D-,L-defects in ice structure.

We showed that electrophysical and physico-chemical phenomena on interface boundary in frozen soils are responsible for: change of actual soil acidity on more acid side; shift of physico-chemical equilibriums including carbonate - calcium equilibrium; and electroomosmotic currents of moisture to the front of freezing.
