Correct Answer: Option (D) — 1, 2, 3 and 4

Concept & Option Breakdown

Standard Reference Verified

All four are recognized methods of soil conservation:

  1. Crop rotation maintains soil structure, prevents nutrient depletion, and curbs soil degradation.
  2. Sand fences trap blowing sand in arid and coastal zones (e.g., western Rajasthan), stabilizing dunes and protecting fertile soil.
  3. Terracing creates stepped platforms on slopes to reduce runoff velocity and water erosion.
  4. Wind breaks (shelterbelts) reduce wind speed across fields to prevent wind erosion.
