Question

suggest any three programmes for prevention of soil pollution in view of avoiding pesticides

Answer 1

-Reducing the use of or finding natural alternatives to toxic substances can help prevent soil pollution.
-Reuse & recycle;contribute less waste to help prevent soil pollution.Purchase glass & other reusable containers instead of throwing away plastic or paper regularly.
-Proper solid waste treatment.

Answer 2

Pesticides are the toxic chemicals which are used to destroy pests. They not only disturb the ecosystem but also pollute the soil. To prevent soil pollution caused by pesticides following programmes should be implemented.

1. Rotation of crops

2. Biological pest control

3. Development of genetic resistant strains

1. Rotation of crops:

• Same crop should not be grown in the same field in successive seasons.

• As the pest which grow on one crop never grows on the other they can be kept under control naturally.

2. Biological pest control:

• In this method pests are controlled by some biological process instead of using chemical pesticides.

• Using predators, using hormone like pheramones, sterilization of the insect pests and utilisation of biological pest repellents such as neem oil,etc., are some of the biological pest control methods.

3. Development of genetic resistant strains:

• Nowadays using genetic engineering pest resistant strains are being produced.

• If use these crops never get affected by the pest so no need to use pesticides.
