WebFeb 10, 2016 · The adsorbed cations replenish the ions in the soil solution when concentrations decrease due to uptake by plant roots. Cation exchange capacity (CEC) is a measure of the total negative charges within the soil that adsorb plant nutrient cations such as calcium (Ca2+), magnesium (Mg2+) and potassium (K+). As such, the CEC is a … WebAlthough CEC has value in soilless media, it is not as significant when it comes to nutrient exchange and pH management as it is with the soil.
