Question: how to calculate percent base saturation?
Answer: Base Saturation (%) = (Base cations/CEC) x 100.
Calcium Saturation (%) = (Calcium cations/CEC) x 100.
Cation exchange capacity (CEC) = Base cations + Acid cations =12.4 + 4.8.
Base Saturation (%) = (Base cations/CEC) x 100.
= (12.4/17.2) x 100.
Calcium Saturation (%) = (Calcium cations/CEC) x 100.
= (10/17.2) x 100.
