Calculate percent base saturation of soil

WebTo calculate the percent base saturation, divide the sum of the K, Mg, Ca, and Na (the bases) in meq/100g soil by the CEC (all these values were calculated above). Multiply the result by 100%. Example: K = 0.28 meq/100g soil. WebThe pH of the soil was 4.0. Calculate the CEC (cmolc/kg), percentage base saturation (PBS) and percent acidic saturation (PAC) per kg of the soil. The cations on an exchangeable site of a 10-g soil were displaced by repeatedly washing by a salt and found to be 20 mg Ca+2, 1.15mg Na+1, 9.75mg K+1, 3mg Mg+2, and 4.5mg Al+3.
