A.
25%
Answer
B.
80%
C.
75%
D.
133.5%

Answer: Option A

Solution

Answer: Option A
Solution:
To calculate the percent base saturation, divide the sum of the K, Mg, Ca, and Na (the bases) in meq/100g soil by the CEC. Multiply the result by 100%.
Based on the formula A soil with 20 me/100g CEC and % me/100g exchangeable H will have a base saturation of 25%.
