All of these choices are good for soil conservation.

Planting crops parallel to the contours of the slope helps to retain water and soil in place, reducing the loss of topsoil. Leaving crop residues in place adds organic matter to the soil, which can improve soil health and structure, and also helps to retain moisture in the soil. Planting grass in natural drainageways on the slope helps to slow down water flow, reducing erosion and allowing water to infiltrate the soil. Using all of these methods together can provide a comprehensive approach to soil conservation on gentle slopes.
