WebThe clay content, the type of clay minerals present, and the organic matter content determine a soil's CEC. *Unit is centimole of charge per kilogram of colloid; another common unit for expressing CEC is me/100g (milliequivalents/100 grams). Note … Web14.3.2.8 Cation Exchange Capacity and Base Saturation. Cation exchange capacity (CEC) gives an insight into the fertility and nutrient retention capacity of soil. Certain soil minerals, such as clay, particularly in combination with organic matter, possess a number of electrically charged sites, which can attract and hold oppositely charged ions.
