How does contour farming help with water management?

• A. It maintains water at a constant level
• B. It directs runoff into large ponds
• C. It reduces water runoff by following the land's contours
• D. It increases the amount of water available for irrigation

Answer: (C)

Contour farming is an effective agricultural practice that helps manage water efficiently by reducing water runoff. By plowing and planting across the slope of the land, this method creates natural barriers that slow down the movement of water. When rain falls, the water collects in the furrows created by the crops planted along the contours, allowing it to soak into the soil rather than flowing quickly downhill and being lost. This also aids in reducing soil erosion, as the water is less likely to displace soil when it is absorbed gradually. Consequently, contour farming promotes better water conservation and enhances soil moisture retention, ultimately leading to healthier crops and improved water management in agricultural practices.
