Water run-off can cause erosion and loss of nutrients. The following methods help reduce it:
• Contour tillage reduces the speed of surface runoff by aligning farming operations along the natural contours.
• Strip cropping breaks the water flow with alternating crop types.

Together, they effectively reduce erosion and enhance water infiltration, making (d) the correct answer.
