What is soil pollution and its effects?
Soil pollution affects the health of humans, plants, and animals.

When animals or human beings consume these crops or plants the toxic material can pass into their body.
What are the effect of soil pollution in the environment?
The study found that soil pollutants from waste dumpsite could directly or indirectly cause emission of ammonia, methane, hydrogen sulphide, carbon monoxide, oxide of sulphur and nitrogen, and particulates matters into the atmosphere. Most of the aerosols have adverse effect on human health on exposure.
What are the effects of soil pollution on agriculture?
After-Effects of Soil Pollution It can decrease the quality of the crop. Regular use of chemical fertilizers, inorganic fertilizers, pesticides will decrease the fertility of the soil at a rapid rate and alter the structure of the soil. This will lead to decrease in soil quality and poor quality of crops.

How many types of soil pollution are there?
Soil contaminants can exist in all three phases (solid, liquid, and gaseous).
How do we control soil pollution?
i. Reducing chemical fertilizer and pesticide use: Applying biofertilizers and manures can reduce chemical fertilizer and pesticide use. Biological methods of pest control can also reduce the use of pesticides and thereby minimize soil pollution.
What is major control of soil pollution?
Recycling and Reuse of wastes: To minimize soil pollution, the wastes such as paper, plastics, metals, glasses, organics, petroleum products and industrial effluents etc should be recycled and reused. Nuclear explosions and improper disposal of radioactive wastes should be banned.
