Chemistry of Saline Soils and Their Physical Properties

  • Chapter

Summary

An outline of the forces involved in clay particle interaction (swelling and dispersion) is given as a background for the interpretation of the physical behaviour of sodic soils, especially in relation to electrolyte levels. The electrolyte concentration below which appreciable decreases in soil permeability are encountered has been termed the threshold concentration and this concentration increases with the degree of sodium saturation of the soil colloids. The application of the threshold concentration concept to the management and reclamation of sodic soil is discussed.
