Question

Quizplus · Accepted Answer

CEC (cation exchange capacity) is the measure of the soil's ability to hold and exchange positively charged ions (cations) such as calcium, magnesium, and potassium. A high CEC means that soil colloids (tiny particles of clay and organic matter) can store and exchange more cations. This is considered desirable as it means that there will be more soil nutrients available for plant growth.
