ABSTRACT

The process of vermiculture may take a number of forms (see other chapters) but is de¤ned simply as the growth and maintenance of earthworm cultures over a period of time. These earthworms must be self-sustaining, such that if some are removed for use elsewhere, then those remaining will continue to multiply and thus offer further opportunities for stock removal. For this process to be successful, the culture medium must be acceptable to the earthworms, and a type of food (which can form the bulk of the culture medium itself) needs to be supplied. The rate of food application will depend on a host of factors, such as its nutritional value, the species
