Cation exchange capacity (CEC) is a measure of the soil's ability to retain and supply nutrients, specifically the positively charged nutrients called cations.
Cation exchange capacity refers to the ability of soil to store nutrients (e.g., calcium, magnesium, and potassium) for future plant uptake.
Typical range of CEC in darker colored soils is 15 to 25 milli-equivalents/100 g soil.
