Earthworms are segmented, tube-shaped worms
belonging to phylum Annelida. These are habituating on healthy soils digesting
live or dead organic matter. The following are benefits of an earthworm to a
soil:
*Earthworms create water way systems, that is, water
can seep quickly into the soil, by digging burrows vertically.
*Earthworms forms lasting burrows or mingling the
soil with organic matter to make the soil more porous, thus, more oxygen to
help the plants’ roots.
*Earthworms reduce the firmness of the soil and
improve the cultivation of land.
*Earthworms consume organic matter as well as mix it
with the soil.
