What Are Some Soil Erosion Solutions?
Soil erosion solutions include increasing ground cover, mulching, preventing tillage and building structures. The type of solution depends on the area in which the erosion occurs.
Soil erosion occurs because of water run-off, tillage, agricultural practices, construction and nature. The result of erosion is the removal of top soil and its vital nutrients. There are various solutions to soil erosion, which depend on the conditions under which erosion occurs.
Erosion control in urban areas often relates to rainwater run-off and construction issues. Construction involves grading and clearing of land, which moves top soil and increases the possibility of erosion in the area. Erosion at construction sites contributes to drainage system clogs due to the sediment that is washed off the site. Various erosion solutions are effective for construction and urban areas, including:
- Vegetative ground cover
- Gravel access paths
- Silt fencing
In agriculture, tillage management is an effective soil erosion measure that minimizes the removal of top soil during field preparation. Conventional tillage practices involve high rates of soil disturbance and lead to high erosion risk; plant residues are turned under in the process, which disturbs greater amounts of top soil. Conservation tillage encourages less soil mixing and increased plant residue, which enables the ground to remain covered and less susceptible to runoff or wind.
Mechanical forms of erosion management include the use of flumes and furrows, debris dams and land smoothing.
