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.
