Main Characteristic

Cation exchange capacity instrument measures the saturated cations, exchanging with the other special cations.

Cation exchang capacity is a total amount of the negative charges that soil have.

They are saturated with Al1³⁺, Ca²⁺, Mg²⁺, NH⁺⁴, K⁺, Na⁺, H⁺, etc.

This method is widely used as an index that evalutes the soil fertility
