cation-exchange capacity wikipedia - EAS
- Cation-exchange capacity ( CEC) is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules (cations), but allow these to exchange with other positively charged particles in the surrounding soil water.

Cation-exchange capacity
yamm.finance/wiki/Cation_Exchange_Capacity.htmlIn soil science, cation-exchange capacity or CEC is the number of exchangeable cations per dry weight that a soil is capable of holding, at a given pH value, and available for exchange with the soil water solution. [1] CEC is used as a measure of soil fertility, nutrient retention capacity, and the capacity to protect groundwater from cation contamination.
