What agricultural practice is required for Class 3 soils?

Class 3 soils are typically characterized by moderate limitations for agricultural production and, as a result, they often require moderate conservation practices to ensure sustainable productivity. These soils can support various crops but may face challenges such as erosion, water drainage issues, or nutrient management. Implementing moderate conservation practices helps to mitigate these limitations, promoting soil health and enhancing the land's ability to support crops.

Examples of moderate conservation practices might include contour farming, crop rotation, and cover cropping, which can improve soil structure, reduce erosion, and maintain fertility. Such practices are essential for maximizing the productivity of Class 3 soils while protecting them from degradation over time. The other choices do not adequately address the specific needs of Class 3 soils in terms of conservation and management, making moderate conservation practices the appropriate requirement for these soils.
