It makes the soil fertile. Earthworms are like natural ploughers as it brings subsoil to the top.
Soil contains partially decomposed organic matter that the earthworm extracts its food from and excrete the mineral parts of the soil as waste. This waste is mixed with the worms urine and becomes a very useful plant fertilizer compared to the original organic matter which may not even be accessible to the plants.
An earthworm, while moving, chews up some soil and spits out the same amount of soil back into the ground. The soil which was eaten becomes fertile and more plants will grow on fertile soil. therefore, an earthworm helps a farmer by making soil fertile.
