Question

Given below are two statements:
Statement (I): Land grading is beneficial in unirrigated areas to conserve moisture.
Statement (II): Land smoothing is the final operation in land levelling.
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:

- Grading: Major earth movement.
- Smoothing: Final touch-up operation using a land float.
Both processes work together to optimize water use efficiency in both rainfed and irrigated fields.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Land grading and levelling shape the field surface to facilitate uniform water distribution, reduce soil erosion, and manage runoff.

Step 3: Detailed Explanation:
-

Statement I evaluation: In unirrigated (dryland/rainfed) fields, land grading creates a uniform surface that prevents water from ponding in depressions or running off rapidly from high points. This ensures uniform rainfall infiltration, conserving soil moisture across the field. Thus, Statement I is correct.
-

Statement II evaluation: The land levelling process involves initial bulk earth movement (grading) followed by a finishing operation. Land smoothing uses floats or smoothers to eliminate minor surface irregularities and complete the field preparation. Thus, Statement II is correct.

Step 4: Final Answer:
Both Statement (I) and Statement (II) are correct.
