Plantings, wood-fiber mats, mulch and retaining walls are all methods of soil erosion prevention. Erosion control is vital for maintaining topsoil that provides plants with important nutrients.Continue Reading
Planting vegetation is among the more natural ways to control soil erosion. Wildflowers, small trees and shrubs are some of the best choices for erosion control. Plants provide a barrier against wind, and their roots help keep soil in place. Plants that provide ground cover by spreading out are a perfect choice to combat erosion.
Mats made of wood fiber provide stability to soil in small areas. Ornamental plants, vegetable crops and trees are able to grow through the matting, providing a double layer of protection to soil. Wood mulch is an erosion control method similar to matting. The mulch layer stabilizes the soil and maintains its pH while allowing vegetation to grow. Mulch prevents erosion by allowing water to filter through slowly so that the soil has more time to absorb the water. Because both of these options involve wood, they are natural and simply biodegrade over time.
Retaining walls work best in combination with other control methods. The low wall keeps water inside garden beds so that soil has a chance to absorb it.Learn more about Erosion & Weathering
While coastal erosion is not completely preventable, the use of retaining walls can help minimize the damage and slow the process. Through the use of man-made walls that line the coastlines, the erosion can be slowed, according to About.com.Full Answer >
Wild Again states that deforestation can contribute to soil erosion, flooding and droughts. In many countries, there has been a marked increase of flooding in areas that have experienced deforestation.Full Answer >
The three major types of erosion are the transporting of soil or rocks by moving water, wind or ice. Water is the primary force behind erosion. The waves of the ocean, movement of a river and falling of rain are all ways water transports materials from one location to another.Full Answer >
Erosion is a process that causes the soil surface to wear out; geological erosion is caused naturally by water, wind or gravity, and accelerated erosion is caused by human use of land. Geologists estimate that 70 percent of soil erosion is caused by human activities like excessive construction, agriculture, surface mining and forestry.Full Answer >
