摘要
An increase in the soil water content results in a decrease in the electrical resistivity of soil. This relationship obeys an exponential equation. When the water content is below the range of capillary-film water, the clearest relationship between the electrical resistivity and water content is observed, which allows the soil and ground waters to be studied. At a high water content, the dependence of the electrical resistivity on the content of exchangeable anions, the pH, and some other properties is detectable.
