Which farming practice reduces soil erosion by minimizing soil disturbance?

• A. Conservation tillage
• B. Mulching
• C. Crop rotation
• D. Irrigation

Answer: (A)

Conservation tillage centers on keeping soil disturbance to a minimum while leaving crop residues on the field. By not turning the soil over as deeply or as often, the soil structure stays more intact and a protective layer of crop stubble or residue covers the surface. That surface cover acts like a shield, reducing the impact of raindrops, slowing down surface runoff, and improving water infiltration. All of this helps keep soil in place and cuts erosion, especially on sloped ground or during heavy rains. Mulching provides surface protection from evaporation and erosion, but it isn’t defined by reducing the soil disturbance during farming operations. Crop rotation aids soil health and can reduce erosion indirectly by keeping ground cover and roots in place, but the defining feature asked about is lowering soil disturbance. Irrigation affects erosion mainly through water management and drainage, not through minimizing soil disturbance.
