The water break also allows more time for the water to settle into the soil. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off which is a major cause of top soil loss and soil erosion. Contour farming is considered an active form of sustainable agriculture.įreebase Rate this definition: 3.0 / 8 votesĬontour ploughing or contour farming is the farming practice of ploughing and/or planting across a slope following its elevation contour lines. Soil erosion prevention practices such as this can drastically decrease negative effects associated with soil erosion such as reduced crop productivity, worsened water quality, lower effective reservoir water levels, flooding, and habitat destruction. Contour ploughing helps to reduce soil erosion. A similar practice is contour bunding where stones are placed around the contours of slopes. Tillage erosion is the soil movement and erosion by tilling a given plot of land. This method is also known for preventing tillage erosion. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally furrows that curve around the land and are level. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy precipitation, allowing more time for the water to settle into the soil.
