Soil supports life
•Water:Utilized for growth of plants
•Carbon: Utilized in form of organic matter in soil
•Nutrients: Provided as mineral and recycled through decaying matters
in soil

5. HOW IS IT CAUSED?
Deforestation
Soil erosion is produced by
deforestation
Use of Pesticides
The soil loses its fertility for
overuse of pesticides
Landfill
Leach harmful chemicals such as
chlorides and heavy metals into soil
Discharge ofIndustrialWaste

useless
Soil Pollution

6. EFFECTS OF SOIL POLLUTION
Agricultural
•Reduced soil fertility
•Increased erodibility
•Loss of nutrient
Industrial
•Increased salinity
•Release of pollutant gases
•Reduced vegetation
Urban
•Clogging of drains
•Public health problems
•Pollution of drinking water sources
Wildlife
•Loss of habitat
•Extinction of Species
•Negative impact on food chain

7. HOW CAN WE CONTROL SOIL POLLUTION
Reducing chemical
fertilizer and
pesticide use
Reusing of Minerals
Recycling
Reforestation

8. How can
we prevent
Soil
Pollution?
01 02
03 04
Use Plants
Some plants can
extract heavy
metals from soil
Bioremediation
Restores
contaminated sites to
a relatively clean
environment
Avoid Littering
Non biodegradable
wastes should not
be discharged in
soil
Land Farming
Land farming
should be
promoted for
waste treatment
