Calcium Magnesium Exchange Equilibria in Soils1

Abstract

Abstract

Exchange equilibria measurements showed that a hydroxy-Al coated montmorillonite clay had a higher preference for Ca than the original clay. Allophane, an organic soil, and soils which contain amorphous minerals or kaolinite plus gibbsite all showed higher preference for Ca than is expected in montmorillonitic clays and soils.
