Question

Explain how soil pollution and soil erosion could be prevented.

Answer 1

Soil Pollution:

The persistent build-up of toxic compounds in the soil is defined as soil pollution.

Prevention of soil pollution:

1. It is necessary to control the causes of soil pollution in order to prevent it.
2. Minimize the use of plastics: Plastics and polythene bags deplete soil fertility. As a result, these should be properly disposed of, and their use should be avoided if at all possible.
3. Pollutants from industry and households: Some waste products from industries and households pollute the soil. Before being disposed of, these pollutants should be chemically treated to render them harmless.
4. Pesticides and insecticides are two other types of soil pollutants.
5. Instead of chemical fertilizers, use manure.
6. Before being released, industrial waste should be treated. Excessive use of these substances should therefore be avoided.

Soil erosion:

Soil erosion is the process of strong wind and flowing water removing the top fertile layer of the soil (topsoil).

Prevention of soil erosion:

1. Deforestation for industrial purposes is being reduced due to widespread public awareness.
2. Assisting local residents in regenerating the decaying forest
3. Tree planting.
4. Do not overgraze grasslands.
5. In hilly areas, step-farming is used.
