The curves obtained by plotting pH - 1/2p (Ca + Mg) against percent base saturation calculated from the ratio of exchangeable Ca + Mg to the sum of Ca + Mg + Al + H extracted from soils with 1.0N KCl had the characteristic shapes of clay titration curves. The experimental values for some montmorillonitic soils showed close agreement with the theoretical curve calculated for Al-bentonite. The podzolic and glei soils fell along another curve with lime potential values higher than those for the montmorillonitic soils at the same % base saturation indicating that the exchange properties of the soils differed from those of bentonite. No close relation was observed when the cation-exchange capacity (CEC) obtained with 0.9N Ca(OAc) /sub 2/ + 0.1N CaCl/sub 2/ or with 1.0N CaCl/sub 2/ was used to calculate percent base saturation.
