I love the worm bin.
Ive been reading "The Rodale Book of Composting" and here is a few key lines from the book about WORMS:
"If bacteria are the champion microscopic decomposers, then the heavyweight champion is doubtless the earthworm. The earthworm consists mainly of an alimentary canal that ingests, decomposes, and deposits casts continually during the earthworms active periods. As soil organic matter is passed through an earthworms digestive system, it is broken up and neutralized by secretions of calcium carbonate from calciferous glands near the worms gizzard. Once in the gizzard material is finely ground prior to digestion. Digestive intestinal juices rich in hormones, enzymes, and other fermenting substances continue the breakdown process. The matter passes out of the worms body in the form of casts which are the richest and finest quality of all humus material. Fresh casts are marked higher in bacteria, organic material, and available nitrogen, calcium, magnesium, phosphorus, and potassium than soil itself. Earthworms thrive on compost and contribute to its quality through both physical and chemical processes."
