Planting crops on the contour of the land has been one of the most successful conservation practices in South Dakota. The small ridges formed by farming on the level have served to hold the rain and snow water until it has had ample time to penetrate or soak into the soil. This has not only reduced erosion by water, but the additional water saved has resulted in higher crop yields.
