To prevent soil erosion, cover and protect all soil with plants or mulch. For large slopes, install a retaining wall to keep soil in place.Continue Reading
In flat areas or moderate slopes, protect soil from wind, rain and snow by keeping the soil mulched well. Add at least 2 inches of wood chips, pine needles or leaves to the top of bare soil to keep precipitation from washing soil away.
Plant seeds in bare soil that has access to water and sun. A turfgrass such as annual rye protects the soil by putting down roots, holding soil in place. Broadcast seeds according to the sowing rate on the package instructions. For best results, use straw or a seed germination blanket to prevent seeds from washing away, keeping seeds in place until they have germinated. This method can be used on flat land and on moderate slopes.
For very steep slopes, a retaining wall can be installed to prevent soil erosion. Very complicated or steep slopes may require the expertise of an engineer. Contact your local government agencies to find out if retaining walls in your area require special approval or must meet specific building codes.
The most effective soil erosion reduction methods include the use of diversions and terraces, mulch, and surface cover; however, the most sustainable method of preventing soil erosion is by using the land responsibly according to its capability. Soil type, slope and the land's position may determine its vulnerability to soil erosion.Full Answer >
By definition, wind erosion involves the erosion, transportation and deposition of soil by the wind, according to Dictionary.com. Wind erosion is often worse during dust storms. Poor farming practices by humans combined with drought conditions such as occurred during the 1930s in the United States increase wind erosion.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 >
Headward erosion occurs when the source of a stream channel is lengthened by erosion of the rock and soil in its basin. This type of erosion occurs in the opposite direction of the flow of the stream.Full Answer >
