Question

Given below are two statements
Statement I: Leaching of saline soils is done by adding organic materials such as farm yard manure, crop residues and green manuring.
Statement II: Reclamation of alkali soils is achieved by treating soils with chemical amendments like gypsum and sulphur.
In light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Hint:

Saline soil reclamation: Leaching with water.
Alkali soil reclamation: Gypsum/Sulphur amendments.
Organic matter improves soil structure, not directly leaching.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question tests knowledge of saline and alkali soil reclamation methods.

Step 2: Detailed Explanation:
Statement I:
Leaching of saline soils is done by applying excess water to dissolve and remove salts.
Adding organic materials like FYM, crop residues, and green manure improves soil structure and aids in reclamation, but it is not the primary method of leaching.
Leaching is primarily a physical process of water application and drainage.
This statement is false.
Statement II:
Reclamation of alkali soils (sodic soils) is achieved by applying chemical amendments.
Gypsum (calcium sulfate) and sulphur are commonly used to replace sodium with calcium.
This statement is true.

Step 3: Final Answer:
Thus, Statement I is false but Statement II is true, which corresponds to option (D).
