Chapter 9 Recommended Methods for Determining Soil Cation Exchange Capacity Donald S. Ross and Quirine Ketterings The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (cations) such as calcium (Ca2+)‚ magnesium (Mg2+)‚ and potassium (K+)‚ by electrostatic forces. Cations retained electrostatically are easily exchangeable with cations in the soil solution so a soil with a higher CEC
