A mathematical model incorporating cation exchage reaction and resolution of aluminum-humus complexes is developed and used to discuss the mechanisms of soil acidification. The model is verified from the viewpoints of the change in concentrations of cations and pH in the leachate from soil exposed to acid rain by comparing the simulated results with data obtained in the artificial acid rain addition experiments. Sensitivity analyses show the importance of Gapon's coefficients for cation exchanege and BAR (bound Al ratio) for release of bases and aluminum and decrease of pH. And Ca+Mg+AI concentration and ratio of (Ca+Mg)/(Ca+Mg+Al) in solution extractedwith buffer solution of 0.5 M acetic acid and anmonium acetate (pH 4.7) are shown to be excellent indices for soil acidification.
