Soil pollution refers to the contamination of soil with anomalous concentrations of toxic substances.
Example: Soil contamination that includes high levels of benzene raises the risk of leukaemia.
Soil pollution can be controlled by the following measures:
- By reducing the use of plastics, we can reduce soil pollution.
- By controlling the use of chemical fertilisers and pesticides, we can control soil pollution.
- Treating industrial waste before releasing.
Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water. Soil erosion can be controlled by the following measures:
- Plant trees on barren lands to limit erosion of soil.
- Add mulch and rocks to prevent the plants and grass underneath to prevent soil erosion.
- Mulch matting can be used to reduce erosion on the slopes.
- Put a series of fibre logs to prevent any water or soil from washing away.
- A wall at the base of the slope can help in preventing the soil from eroding.
- Every household should have a proper drainage system so that water flows down into proper water collecting systems.
