Question
How can the soil polluted by acid rain be made fertile again?
✓
Answer
- The soil polluted by the acid rain is made fertile again by using bacteria.
- Acidophillium spp. and Acidobacillus ferroxidens are the bacteria which have the capacity to use sulphuric acid as their energy source.
- Since this sulphuric acid present in the acid rain, can be controlled by these bacteria.
- In this way, bacteria can control the soil pollution occurring due to acid rain, making the soil fertile again.
