Explain some ways to reduce soil erosion
What will be an ideal response?
The best way to reduce erosion on disturbed slopes is to terrace the slope to slow down the flow of water. Plants should be planted along contours of slopes. Alternating crops aids in soil replenishment and a crop such as hay can provide cover of the entire field. Windbreaks are key to slowing wind erosion.
