Question

Recommended strip width for wind strip cropping are: A. Sandy soil -- \(6.0\ \text{m}\), B. Loamy sand -- \(7.0\ \text{m}\), C. Sandy loam -- \(30.0\ \text{m}\), D. Loam -- \(75.0\ \text{m}\), E. Silt loam -- \(85.0\ \text{m}\).

• A. A and B only
• B. A, B and C only
• C. A, B, C and D only
• D. A, B, C, D and E

Hint:

In wind strip cropping, coarse sandy soils require narrower strip width than loam and silt loam soils.

Answer 1

The Correct Option is D

Concept:
Wind strip cropping is used to reduce wind erosion by arranging strips of crops across the direction of prevailing wind.

Step 1: Understand strip width.
Strip width depends on soil texture. Coarser soils are more erodible by wind and therefore require narrower strips.

Step 2: Check given values.
The recommended values given are: \[ \text{Sandy soil}=6.0\ \text{m} \] \[ \text{Loamy sand}=7.0\ \text{m} \] \[ \text{Sandy loam}=30.0\ \text{m} \] \[ \text{Loam}=75.0\ \text{m} \] \[ \text{Silt loam}=85.0\ \text{m} \]

Step 3: Final selection.
All the given statements are correct. \[ \therefore \text{Correct Answer is (D)} \]
