Which of the following helps prevent soil erosion and promotes sediment trapping?

Vegetative cover is a critical component in preventing soil erosion and promoting sediment trapping. Plants and vegetation play a significant role in stabilizing the soil through their root systems, which bind the soil particles together and reduce the likelihood of them being washed or blown away by water or wind. Additionally, the foliage provides a protective layer over the soil, reducing the impact of raindrops and preventing soil dislocation.

When vegetation is present, it not only prevents erosion but also aids in sediment trapping. As rainwater flows over landscapes, the vegetation slows down water movement, allowing sediment to settle out of the water rather than being carried away. This natural filtration process helps maintain soil quality and reduces the amount of sediment that would otherwise enter waterways, thus protecting aquatic environments and maintaining water quality.

While soil compaction can sometimes temporarily reduce erosion, it ultimately leads to poor water infiltration and can exacerbate erosion issues. Water management is vital for controlling water flow but does not directly influence soil stabilization like vegetation does. Granular fertilizers, while beneficial for plant growth, do not play a role in preventing erosion by themselves.
