WebMar 24, 2024 · The amount of acid or base required to change the charge of the soil is known as acid saturation (base saturation). To calculate CEC, divide the acid/base saturation by the soil's bulk density. The result will be the CEC, measured in meq/100g. WebThe method has detection limits of approximately of 1 ppm or 0.01 meq/100g for each cation. The estimation of cation exchange capacity is reported as the sum of the results for K, Ca, Mg, and Na.
