what is the effect of soil erosion? what will you do to protect the community?
Answers
The effects of soil erosion are loss of fertile land, increased pollution, sedimentation in rivers, etc. We could protect our community from soil erosion by planting a cover crop, mulching etc.
- Explanation: Soil erosion is the form of soil degradation.
- The displacement of the upper layer of soil is said to the soil erosion.
- Soil erosion occurs when the impact of water or wind get detaches and removes the soil particles.
- When the soil particles get removed from the soil it causes the soil to deteriorate.
- Soil erosion is caused due to various problems like overgrazing, deforestation, sedimentation in rivers, etc.
- We could protect our community from soil erosion by adopting various preventive measures like placing a crushed stone and other heavy materials in heavily used areas, planting a cover crop, mulching, and above all by maintaining a healthy, perennial pant cover.
Answer:
Soil erosion is primarily problem for agriculture, although massive erosion events can pose a risk to structures. Erosion generally is not so fast as to pose a direct risk to human life. Rapid mass wasting of that kind is usually referred to as a landslide.
Erosion makes soil less fertile and productive. It does this by damaging the physical structure of soil that plants need to maintain a healthful balance between water and air in the soil. It also damages the soil’s chemical fertility by washing away the topsoil. Topsoil is the upper soil layer that is richest in plant nutrients due to the accumulation of organic matter on the surface.
The main strategies to prevent erosion are biological and physical. Biological erosion control is accomplished by maintaining a plant layer that covers the soil surface, protecting it from wind and rain. Plant roots also hold the soil in place. Physical methods are designed to reduce soil slope and length. They include contour plowing, terrace farming, contour ditches, and other methods that interrupt the downhill flow of water. Many farmers now reduced tillage or no-till methods to reduce soil erosivity.
hope it helps you!
