As they deposit their castings, their mucous is deposited into the soil. It helps to slow the release of nutrients and prevents them from being washed away with the first watering. Earthworm manure or casts are richer in minerals than the soil in which the earthworms work to breakdown their organic matter

Earthworm goes up and down in the soil, hence the layer of soil at bottom comes up.
As farming is done the fertility of upper part is absorbed and bottom has some fertility in it.
Therefore it is correct to say that earthworm increases soil fertility....
Hope u like and understand the answer....
If any quarries about it ask me ...
