Contour farming is an agricultural practice that involves planting crops perpendicular to the slope of a field to reduce soil erosion caused by water runoff. Some synonyms for contour farming include terrace farming, hillside farming, slope farming, and bench terracing. These methods all involve planting crops in a way that matches the natural contour of the land to slow down water and prevent it from washing away valuable topsoil. Other terms used to describe this technique include contour strip cropping, contour levee farming, and contour plowing. Regardless of the term used, the goal is the same: to reduce soil erosion and improve agricultural production in challenging landscapes.
