Question

Given below are two statements:
Statement (I): Sulphur is the major problem in sodic soils.
Statement (II): They have an ESP \(>15\), the \(EC_e\) is \(<4\) dS \(m^{-1}\), and the lower limit of the saturation extract SAR is 13.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

To remember salt-affected soil classification:
- Saline: \(\text{EC} > 4\), \(\text{ESP} < 15\), \(\text{SAR} < 13\), \(\text{pH} < 8.5\).
- Sodic: \(\text{EC} < 4\), \(\text{ESP} > 15\), \(\text{SAR} \ge 13\), \(\text{pH} > 8.5\).
- Saline-Sodic: \(\text{EC} > 4\), \(\text{ESP} > 15\), \(\text{SAR} \ge 13\), \(\text{pH} \approx 8.5\).

Answer 1

The Correct Option is D
