Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Contour cultivation means carrying out cultivation operations along contour lines across the slope.
Step 1: Reduction of erosion.
Contour cultivation reduces sheet and rill erosion by slowing down runoff. \[ A \text{ is correct} \]
Step 2: Reduction of sediment transport.
Since runoff velocity decreases, sediment transport also decreases. \[ B \text{ is correct} \]
Step 3: Increase in infiltration.
Water gets more time to enter the soil, so infiltration rate improves. \[ C \text{ is correct} \]
Step 4: Check D and E.
Stabilizing sand dunes and providing fuel/fodder are not direct objectives of contour cultivation. \[ D \text{ and } E \text{ are not selected} \] Thus: \[ A,B,C \] \[ \therefore \text{Correct Answer is (D)} \]
