It is suggested that diffused-adsorption potentials in soils are defined by soil organomineral gels. This assumption is experimentally confirmed. The excess cations and anions from salts are kept in soils by means of gel structure varying under the influence of salts. Therefore arising potentials are properly termed diffused-sorption potentials.
