The (CEC) is a term used to describe the holding capacity of a particular soil for positively-charged elements (cations). It may also be defined as the capacity for soil to exchange cations for another. In simple terms, the higher the clay content, the higher the CEC. This is because clay particles have the greatest surface area per unit volume of soil, therefore, can hold the most cations.
