Which method can assist in preventing soil erosion in landscaped areas?

Using ground covers is an effective method for preventing soil erosion in landscaped areas. Ground covers are low-growing plants that blanket the soil, helping to reduce the impact of rainfall on the soil surface. By covering the ground, these plants provide a protective layer that shields the soil from being washed away by water runoff.

The roots of ground cover plants also help to anchor the soil in place, which stabilizes the ground and reduces the likelihood of soil movement. This is particularly important in areas with slopes or where the soil is prone to erosion due to heavy rain, wind, or human activity. Additionally, ground covers can improve water retention in the soil by reducing evaporation, further protecting the soil structure and promoting healthy plant growth.

In contrast, options such as installing fences do not have a direct effect on soil stability; fertilizers can enhance plant growth but do not address erosion; and increasing runoff would exacerbate erosion rather than prevent it. Thus, utilizing ground covers is a proactive approach to soil conservation in landscape management.
