What is the recommended slope range for effective contouring?

The recommended slope range for effective contouring is between 2-9%. This range is optimal because it allows for proper water management and soil conservation by enabling the natural contours of the land to be utilized in preventing soil erosion.

At slopes within this range, the effectiveness of contour farming practices significantly increases, as the arrangement of crops and the placement of water barriers can significantly reduce runoff and promote water infiltration. Slopes that are too steep may lead to excessive erosion and make it difficult to manage the land effectively, while slopes that are too flat may not adequately divert water away from potential problem areas. Therefore, the 2-9% slope range strikes an ideal balance to support sustainable agricultural practices and soil health.
