Manual of On-Farm Vermicomposting and Vermiculture The Manual of On-Farm Vermicomposting and Vermiculture by Glenn Munroe of the Organic Agriculture Centre of Canada is a comprehensive guide to the breeding and commercial use of earthworms. Starting with a chapter on the basics of vermiculture and vermicomposting the book covers nutrition and environmental essentials and then moves on to a comprehensive study of different verimculture systems. The final chapter examines the commercial viability of a number of worm-related opportunities and includes a comprehensive list of references and details of on-farm trials (56 pages).

Vermicomposting as an Eco-tool in Sustainable Solid Waste Management (2.1MB) This report is an alternative option to solid waste management based on the application of earthworms and generally termed as vermicomposting. This report describes the various treatments with earthworms from industrial sludge to kitchen waste. It also highlights the biology of these worms and how to maintain and prepare suitable bedding for this biological treatment of solid waste. This report also provides basic information and vermicomposting experiences for those involved in vermicomposting or breeding of the worms.

Co-Composting Paper Mill Sludges with Fruit & Vegetable Wastes (3.4MB) The research presented in this report is a scoping study that addresses several research issues pertinent to compost production and utilisation. It provides a fully-documented case study of the development of an in-vessel composting process and of the testing of the compost produced. It shows how computer simulations can help in process development and optimisation. It examines the possibility that vermicomposts might have ‘special’ properties over and above those of normal composts. Whilst the research focuses on one particular composting substrate, paper mill sludge, many of the findings could be of much wider interest (180 pages).
Raising Earthworms Successfully by Rhonda Sherman (330KB) A 26 page booklet prepared by the North Carolina Extension Service - contents include a discussion on the markets for earthworms and vermicompost, the classification and biology of earthworms as well as setting up and running a growing operation. There are also sections on feeding, harvesting and dealing with earthworm pests.

Vermicomposting of pre-composted mixed fish/shellfish and greenwaste. In this study, partially composted mixed fish/shellfish and green waste was further vermicomposted on a large-scale for seven weeks. The composition of the pre-composted waste was such that the earthworms appeared to be reluctant to enter the waste directly for the first three weeks but then actively processed the waste into a vermicompost capable of being used as a basis for the formulation of high value composts (1.7MB).

Optimum Moisture Requirement during Vermicomposting. Advancement in vermiculture technology requires a detailed understanding of functioning of the system. In this paper, the effect of moisture content variation using epigeic (surface burrowing) earthworm (Perionyx excavatus, Perrier, 1872, family: Megascolecidae) to predict optimum moisture requirement during vermicomposting is investigated.

Building a Sustainable Business: A Guide to Developing a Business Plan for Farms and Rural Businesses (3.3MB). Producers considering innovative management practices and immature markets use business plans to map out strategies for taking advantage of new opportunities such as organic farming, on-farm processing, direct marketing and rural tourism. A business plan helps producers demonstrate that they have fully researched their proposed alternative; they know how to produce their product, how to sell what they produce, and how to manage financial risk (280 pages).

Earthworms (Annelida: Oligochaeta) of the Columbia River Basin Assessment Area by Sam James. The three main ecological types of earthworms found in the basin assessment area are epigeic, endogeic, and anecic. Each type has a different life history pattern, resource requirement, and ecological function and this report summarizes the main issues about the ecology of earthworms and their impact on the physical and chemical status of the soil.
