Ground cover such as vegetation, trees, and grass roots help to hold the topsoil in place and prevent erosion by wind and rain. Mulching and practicing conservation methods like terracing or contour plowing can also help protect the topsoil from erosion.
Deforestation can affect topsoil in two significant ways. First leaves and branches that fall from trees as well as fallen trees themselves decompose. This decomposed matter is a major component of topsoil. If an area is deforested then much less new topsoil will be formed. Secondly, when an area is deforested wind and rain can cause the unprotected topsoil to be blown or washed away.
