Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).

Assertion (A) : Ammonium-based fertilisers are the major contributors to soil acidification.
Reason (R) : Especially the non-leachable nitrogen ions which have been taken up by plants contribute to the soil acidity.

In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Nitrification of 1 mole of \(\text{NH}_4^+\) releases 2 moles of \(\text{H}^+\) ions, making ammonium fertilizers more acidifying than nitrate-based fertilizers.

Answer 1

The Correct Option is A
