How do plant roots help prevent soil erosion?

Answer 1

Vegetation prevents erosion in several different ways. First, the roots of plants hold the soil in place and keep it from washing away in rainstorms. Second, vegetation provides ground cover which keeps hard rain from washing away soil. Third, trees provide windbreaks which keep high winds from blowing away top soil. Thus, it is important to have farmers use no-till farming techniques. It is also important to replant the trees planted by the Civilian Conservation Corps in the 1930s which provided the windbreaks that helped stop the dust bowls in the United States.

Answer 2

The movement of plant roots create Poles or holes in the soil which make water movement easily instead of the water running throught to carry soil particles.

Answer 3

Yes. They can also help protect the soil with leaves to prevent precipitation striking the soil with enough force to dislodge it.
