Out and about

They live in healthy soils, liking the same conditions as plants. They are found worldwide. There are more than 300 species of native worms in Australia as well as many introduced species. The type most commonly found in agricultural soils are actually introduced species, whereas the native ones tend to inhabit undisturbed natural areas.

Reproduction and Life cycle

Earthworms possess both female and male reproductive organs. They lay eggs in the soil which hatch in about three weeks. In ideal conditions they breed up very quickly

Why they are Beneficial

These guys feed on organic matter such as plant debris, bacteria, fungi and other microorganisms. They are able to eat up to half their body weight each day. During this process they create tunnels which aerate the soil as well as improving the structure of the soil. These tunnels also allow for improved drainage and easier pathways for plant roots. The by-product of their eating, castings (worm poo), is a nutrient rich fertilizer for plants. Castings are also very colloidal (able to hold cations and therefore nutrients). The presence of worms is an indicator of healthy soil.
