Worm Composting

Worm composting is the process of administering worms to dead cell matter for composting it. Worm composting works much more quickly than traditional composting, and it is often referred to vermicomposting.

The earthworm species most used in the process (composting worms) are mostly Red Wigglers (Eisenia foetida), but European nightcrawlers (Eisenia hortensis) may also be used, as well as more acid-tolerant worms called dendrobaenas or dendras.
Worm composting is a common activity in locations over the world, although it is particularly large-scale in Canada, Italy, Japan and the US. Worm composting has its uses in farming and landscaping, such as in the manufacture of compost tea.

There are two systems of larger-scale worm composting, the first type using a windrow, which is just a body of bedding materials for the earthworms to live in; and there is always an abundance of organic matter for them to feed on, which is continually added to.

The second system is the raised bed flow-through system, which locates an inch of worm food across the top of the bed while an inch of castings is harvested from below when a breaker bar is pulled across the large mesh screen which constitutes the base of the bed.
Worm composting operatives may wish to note that the most kinds of worm composting worms – Eisenia foetida, Eisenia andrei and Lumbricus rubellus – feed most rapidly at temperatures of 59 to 77 degrees Fahrenheit (15-25 degrees Celsius). They can survive at 50 degrees Fahrenheit (10 degrees Celsius).
