How does contour plowing conserve soil? Contour plowing/ploughing conserves soil by following the lay of the land and creating ridges that form a water break to prevent soil erosion. Furrows that do not follow the lay of the land cause rapid runoff during rainfall by forming a convenient channel for the water to flow downhill.
