What conservation practice typically leads to improved soil health and reduced erosion?

• A. Crop rotation
• B. Monoculture farming
• C. Overgrazing
• D. Wetland drainage

Answer: (A)

Crop rotation is a conservation practice that involves alternating the types of crops grown in a particular area across different seasons or years. This method has several positive impacts on soil health and plays a crucial role in reducing erosion. One of the main benefits of crop rotation is its ability to enhance soil fertility. Different crops have varying nutrient requirements and growth patterns, which can help maintain a balanced nutrient profile in the soil. By planting different types of crops, farmers can prevent the depletion of specific soil nutrients that can occur with continuous planting of the same crop, a practice known as monoculture. This not only promotes healthier soil but also helps in breaking the cycle of pests and diseases that often thrive in monoculture systems. Additionally, crop rotation improves soil structure and increases organic matter as different crops contribute different types of root systems and biomass. These improvements lead to better water infiltration, reduced compaction, and ultimately a healthier soil ecosystem. Furthermore, rotating crops can significantly minimize soil erosion. By growing deep-rooted plants in one cycle and shallower-rooted plants in another, farmers can stabilize the soil better and reduce runoff, helping to prevent erosion caused by heavy rains. In contrast, practices like monoculture farming can lead to soil depletion and increased erosion due to the lack of diversity
