Good soil management practices include proper pH level, fertilizing, good tillage practices, adequate irrigation, and which practice?

• A. Crop rotation
• B. Pest control
• C. Mulching
• D. Soil testing

Answer: (A)

Rotating crops is essential because it keeps soil productive by varying nutrient demands and residues each season, and by breaking pest and disease cycles that rely on a single host. Different crops take up nutrients in different ways, so alternating crops helps prevent the depletion of specific nutrients and can improve overall soil fertility. Legumes, for example, can add nitrogen to the soil, while other crops can improve soil structure and rooting depth, aiding water infiltration and drainage. The diverse plant residues left on the field also feed soil biology and increase organic matter, boosting soil health and resilience. While mulching, pest control, and soil testing are valuable components of soil management, crop rotation uniquely supports long-term soil fertility, reduces pest buildup, and enhances soil structure and function.
