how to control soil pollution?​

Answer 1

Answer:

CAUSES OF SOIL POLLUTION - DEFINITION

Soil pollution can be caused by the following-

Drilling of oil refineries

Accidental spills

Acid rain (which is caused by air pollution)

Intensive farming

Deforestation

Genetically modified plants

Nuclear wastes

Industrial accidents

Landfill and illegal dumping

Land erosion

Agricultural practices, such as application of pesticides, herbicides and fertilizers

Mining and other industries

Oil and fuel dumping

EFFECTS OF SOIL POLLUTION - DEFINITION

Effect on health of humans: Considering how soil is the reason we are able to sustain ourselves, the contamination of it has major consequences on our health.

Effect on growth of plants: The ecological balance of any system gets affected due to the widespread contamination of the soil.

Decreased soil fertility: The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield.

Toxic dust: The emission of toxic and foul gases from landfills pollutes the environment and causes serious effects on health of some people.

Changes in soil structure: The death of many soil organisms (e.g. earthworms) in the soil can lead to alteration in soil structure.

PREVENTION AND CONTROL MEASURES OF SOIL POLLUTION - DEFINITION

The following measures should be taken to prevention of soil pollution-

1. Use of pesticides should be minimized.

2. Use of fertilizers should be judicious.

3. Cropping techniques should be improved to prevent growth of weeds.

4. Special pits should be selected for dumping wastes.

5. Controlled grazing and forest management.

6. Wind breaks and wind shield in areas exposed to wind erosin.

7. Planning of soil binding grasses along banks and slopes prone to rapid erosin.

EFFECT OF SOIL POLLUTION - DEFINITION

Soil pollution affects human beings and animals indirectly through food chains. The effects of soil pollution on environment, human health and other organisms are discussed below.

(i) Land and soil pollution is responsible for loss of fertility and productivity of soil.

(ii) Soil contains many pathogenic bacteria, viruses and intestinal worms which are transmitted to man by the consumption of fruits and vegetables. These pathogens cause various types of diseases.

(iii) Many pesticides are absorbed by plants and reach animals and humans via food chains.

Answer 2

Explanation:

Hello friend,

Good Question !

Here is your answer:-

➔ How to control soil pollution ?

↪First of all,

• What is soil pollution ?

Soil pollution is the polluting/making soil dirty by dumping wastes, radioactive waste,etc which makes the soil incapable of decomposing organic wastes and to grow crops on it.

• How does the soil become dirty ?

By dumping inorganic wastes which the soil can't decompose and radioactive waste which makes the fertility of the soil at the worst position.

• How to control soil pollution ?

By adopting these steps,we can save our soil from being polluted:-

1. Prevent dumping inorganic wastes like plastic,batteries,paint,etc into the soil.
2. Prevent polluting water as the soil beside it can become polluted and incapable of agriculture.
3. Plant more trees as it saves the soil bind in its roots and prevent soil erosion also.
4. Control grazing of cattle as overgrazing make the land barren and soil erosion increase of that land.
5. Don't use chemical fertilizers and pesticides which damage the soil.

hope it helps you.....
