Which practice is commonly associated with improving soil health?

• A. Crop monoculture
• B. No-till farming
• C. Excessive irrigation
• D. Pesticide application

Answer: (B)

No-till farming is commonly associated with improving soil health because it minimizes soil disturbance, helping to maintain the soil structure and its natural ecosystem. By avoiding tillage, farmers preserve organic matter, enhance moisture retention, and protect beneficial microorganisms that contribute to nutrient cycling. This practice also aids in reducing soil erosion, thereby maintaining the soil's fertility over time. Additionally, no-till farming can improve the overall biodiversity of the soil, which is essential for healthy plant growth and agricultural productivity. In contrast, monoculture, excessive irrigation, and pesticide application can lead to soil degradation, reduced biodiversity, and other negative environmental impacts.
