Question

Assertion (A): Gypsum is commonly used for the reclamation of sodic soil.
Reason (R): Reclamation process involves reduction in exchangeable sodium with calcium and its removal from soil solution through leaching.

• 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:

Gypsum helps reclaim sodic soils by replacing sodium with calcium, which is then leached out.

Answer 1

The Correct Option is A

Gypsum provides calcium, which replaces sodium ions in sodic soils. The displaced sodium is leached away through proper drainage, improving soil structure. Hence, both A and R are true and R explains A correctly.
