What Is It?
Worm castings are a fertilizer made from the material that passes through the alimentary canal of worms. This substance is high in both nutrients and beneficial microfauna. Castings are pH neutral and can be used for diverse soil types. They also contain cocoons that promote the colonization of earthworms throughout the soil.
