what is contour ploughing
Contour plowing (or contour ploughing) or contour farming is the farming practice of ploughing across a slope following its elevation contour lines. The rows form slow water run-off during rainstorms to prevent soil erosion and allow the water time to settle into the soil. In contour ploughing, the ruts made by the plow run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level.
