Question

Which is least soul protection leaves on top of soil no soil protection
GPT 3.5
Leaves on top of soil provide some protection for the soil from erosion, but they are not as effective as other methods such as mulch or ground cover plants. Therefore, leaves on top of soil would be considered the least effective form of soil protection. If there is no soil protection at all, then the soil would be completely exposed to erosion and other forms of degradation.
