What about Anion Exchange Capacity when managing/studying soil fertility?
Because cation exchange capacity represents the potential reservoir of cationic nutrients that are bound to the surface of the soil colloids. While anion exchange toxicity has a greater influence on soil fertility under the following conditions:
If the colloid is in a medium where pH > PCZ of colloid: negative charge.
– If the colloid is in a medium where the pH < PCZ of colloid: positive charge.
– If the colloid is in a medium where the pH = PCZ of colloid: zero charge.
