DOI: https://doi.org/10.1007/978-1-4020-3995-9_93

Ion exchange involving cations. In soils the exchange takes place on the surfaces of clay minerals, amorphous inorganic phases and organic matter. The cation exchange capacity (CEC) is the quantity of cations reversibly adsorbed per unit weight of the solid (McBride, 1994, chapter 3). The conventional unit for CEC is cmoles/kg.
