CALCULATION OF PARAMETERS OF DIFFUSE LAYER OF CLAY PARTICLES AND THEIR INFLUENCE ON THE ELECTRICAL CONDUCTIVITY OF THE SOIL

The article discusses the structure of the diffuse layer of colloidal particles of the soil. The authors present analytical expressions for the concentration distributions for the exchange of ions and electric potential through the thickness of the water film covering the particles. Also given the expression for the specific surface conductivity of colloidal particles. The dependence of the conductivity of the soil moisture obtained in the experiment is compared with the calculated dependence.
