Earthworms are called a farmer’s friend. Do you know why?
Your friend is correct,
Earthworm are called friends of farmer because :
- Earthworm moves through the soil that loosens and aerates the soil. This also helps the water to reach the roots quickly.
- Earthworm 's excreta increases the fertility of the soil.
- After their death, they get decomposed and add humus to the soil.
