What is the Cation Exchange Capacity of AZOMITE®?
25 – 30. Cation Exchange Capacity (CEC) is the capacity of soil to exchange positively charged ions between the soil and the soil solution. A positively-charged ion is known as a “cation” because of its attraction to cathodes. CEC is used as a measure of fertility, nutrient retention capacity, and the capacity to protect groundwater from cation contamination.
