 Contour farming is a conservation practice that involves plowing and planting across a slope following its elevation contour lines. These contours form natural pathways for water to flow over the landscape. The main purpose of contour farming is to reduce soil erosion and conserve rainwater. The method works by creating ridges that slow down water runoff and allow it to infiltrate the soil, rather than washing away soil, nutrients, and seeds.

Contour farming is particularly important on steep slopes because the speed of water flowing down the hill can cause a great deal of erosion. By breaking up the slope with these horizontal planting lines, the water's flow is interrupted, which decreases the formation of rills and gullies that can carry away the fertile topsoil. This practice is often used in combination with other soil conservation practices like strip cropping, terracing, and cover cropping to further improve soil retention and prevent water pollution caused by soil erosion. It is a sustainable agricultural practice that can help ensure long-term productivity of the land while also protecting the environment.
