Explain how soil pollution and soil …

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.
