Due to Nitrification process soil pH

A. Increases

B. Decreases

C. Does not affect soil pH

D. None of the above

Answer: Option B

Solution(By Examveda Team)

Due to the nitrification process soil pH Decreases.
As the ammonium -N in fertilizers undergoes nitrification i.e. conversion of ammonium to nitrate in soils by bacteria, hydrogen (H⁺) is released, which can increase acidity. As the percentage of ammonium increases in a given fertilizer, the acidifying potential will also be increased, thus reducing pH.
