C) adding a rock mulch layer to slow water runoff
D) terracing slopes to stop downslope runoff and rill formation

Terracing slopes to stop downslope runoff and rill formation is the most effective and common land use practice to minimize soil erosion on slopes. Terracing involves building a series of level platforms, or terraces, on the slope, which help to slow down water runoff and trap sediment, preventing it from being carried away by the flowing water. This method also helps to stabilize the soil, making it less prone to erosion, and is often used in areas where row cropping or other land use practices are not practical. Planting trees and adding a rock mulch layer can also help to reduce erosion, but are less effective than terracing, particularly on steep slopes. Planting row crops with rows running downhill can actually increase channelization of flow, accelerating erosion, and is not a recommended practice for erosion control on slopes.
