In this work,we study how the salt concentration in various soils influences diffusion-adsorption potentials(DAPs).We find that cations and anions not entering the absorbing complex of the soil are retained by the organomineral gel(OMG)of the soil.Some researchers [1,2] think that DAPs appear due to the different adsorptive abilities and activities of ions in contacting systems and to the travel of more mobile ions from one contacting system to another.
