Cation Exchange Capacity In soil science, Cation Exchange Capacity (CEC) is the maximum quantity of total cations, of any class that a soil is capable of holding at a given pH value available for exchange with the soil solution. CEC is used as a measure of fertility nutrient retention capacity and the capacity to project ground water form cation contamination.
