Question

Given below are two statements: Assertion (A): Contour strip cropping is the growing of erosion permitting crops in strips of suitable widths across the slope on contour, alternating with strips of soil protecting and erosion resisting crops. Reason (R): It shortens the length of the slope, checks movements of run-off, helps desilt if increases the absorption of rain water.

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is not the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Contour strip cropping reduces erosion by slowing runoff and trapping soil particles.

Answer 1

The Correct Option is A

Concept:
Contour strip cropping is a soil conservation practice used on sloping lands.

Step 1: Check Assertion.
In contour strip cropping, erosion permitting crops and erosion resisting crops are grown in alternate strips across the slope along the contour. \[ A \text{ is correct} \]

Step 2: Check Reason.
This practice shortens slope length, slows runoff, traps soil particles and increases water absorption. \[ R \text{ is correct} \]

Step 3: Check explanation.
The reason explains why contour strip cropping helps in soil conservation. \[ R \text{ correctly explains } A \] \[ \therefore \text{Correct Answer is (A)} \]
