Question

The erosion of soil by wind is influenced by all of the following except

• A. Soil texture class factor
• B. Surface roughness factor
• C. Surface cover factor
• D. Wind barrier factor

Hint:

Wind erosion factors:
- Surface roughness, Surface cover, Wind barriers.
- Soil texture affects erodibility but is not a separate factor in standard equations.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of factors affecting wind erosion.

Step 2: Detailed Explanation:
Wind erosion is influenced by the following factors:
- Surface roughness factor (B)
- Surface cover factor (C)
- Wind barrier factor (D)
Soil texture class factor (A): This is not a direct factor used in the wind erosion equation.
While soil texture affects erodibility, the "soil texture class factor" is not a standard factor in wind erosion models.
Thus, option (A) is the exception.

Step 3: Final Answer:
Thus, soil texture class factor is NOT a factor influencing wind erosion, which corresponds to option (A).
