Methods of preventing soil erosion
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. Soil erosion is a naturally occurring process that affects all landforms.
The most effective known method for soil erosion prevention is to increase vegetative cover on the land, which helps prevent both wind and water erosion. Terracing is an extremely effective means of erosion control, which has been practiced for thousands of years by people all over the world. Windbreaks are rows of trees and shrubs that are planted along the edges of agricultural fields, to shield the fields against winds.
Traditional planting methods, such as mixed-cropping instead of monocropping and crop rotation have also been shown to significantly reduce erosion rates. Diversion Structures: Used often for gully control, diversion structures cause water to flow along a desired path and away from areas at high risk for erosion.
