Do you observe any soil pollution in your neighbourhood? What efforts will you make for controlling the soil pollution?

Solution

we have observed soil pollution in nearby agricultural fields. This is due to the use of a lot of fertilisers are chemical substances which help the soil to become fertile. But an excess of fertilisers pass to the groundwater from the soil and as runoff to lakes rivers and seas and are harmful to aquatic animals.

The control of soil pollution can be made by using manure and biofertilizers instead of fertilisers:

Use of manure : manure is a semi-decayed organic matter which is added to the solid to maintain fertility. These are mostly prepared from animal dung and other farm refuse. These are much better than the commonly used fertilisers.
Use of biofertilizers: These organisms are inoculated in water to bring nutrient enrichment of the solid, e.g., nitrogen-fixing bacteria and blue-green algae.
