• A. Poor irrigation practices
• B. Over-cultivation
• C. Cattle grazing
• D. Contour ploughing

Answer 1

Answer:

D. Contour ploughing

Contour ploughing helps to prevent soil erosion by reducing water runoff and promoting water absorption into the soil Contour ploughing mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition.
