WebFeb 26, 2014 · Cation exchange capacity (CEC) is a measure of the total negative charges within the soil that adsorb plant nutrient cations such as calcium (Ca 2+ ), magnesium (Mg 2+) and potassium (K + ). As such, the CEC is a property of a soil that describes its capacity to supply nutrient cations to the soil solution for plant uptake.
