If pH of soil increases, then which of the following statement is false?

A. ZPC increases

B. CEC decreases, AEC increases

C. ZPC decreases

D. AEC decreases, CEC increases

Answer: Option B

Solution(By Examveda Team)

It pH of the soil increases, then
CEC, Cation exchange capacity which is a useful indicator of soil fertility increases with an increase in the pH of the soil.
AEC (Anion exchange capacity) represents the positive charge available to attract anions in soil and is not pH-dependent, as constant-charge soil particles carry no significant positive charge.
