Commercial Vermiculture looks at the opportunities available for joining a true growth industry in vermiculture. The author takes readers through a journey that starts with a look at current efforts in converting tons of organic waste into vermicompost, a high-grade soil amendment. Some landfill diversion sites in California utilize thousands of pounds of redworms to process a variety of organic residues, including yard debris, bio-solids, and the biodegradable fraction of Municipal Solid Waste (MSW). While California's climate allows nearly year-round vermicomposting to occur in outdoor windrows, in-vessel systems are in use in other parts of the country to control key process variables. The emphasis of large vermicomposting sites is upon processing organic waste and production of worm castings for sale. Due to frequent harvesting, worm populations remain fairly steady. In order to start or even expand a vermicomposting operation, redworms are purchased from vermiculture sites, where the emphasis is upon breeding earthworms. Vermiculture operations (worm farms) may not be able to supply the thousands of pounds needed for a large vermicomposting facility.
Frequently asked questions about earthworms are answered in the second chapter, covering such topics as how much do worms eat and how fast will a worm population multiply. In Getting Started, the author offers suggestions for small, medium and large-size operations. Wooden and concrete bins, pits, and heated, insulated bins are covered. Chapter Four, Monitoring Conditions in Worm Beds, looks at temperature, moisture, soil pH, and aerobicity. Earthworm feedstocks, including how to find sources of free feedstocks, are discussed in the fifth chapter. Other chapters in the book cover essential information for preparing worms to be shipped to customers.
What is the value of worm castings? A series of quotations from various authorities on the subject of castings is presented in Chapter Nine. In Earthworms: Yesterday, Today and Tomorrow, the author provides a brief history of the practice of vermiculture, including an inside look at what happened to a million-dollar-a-year worm growing business from the 1970s. The final chapters of this book offer a variety of things that can be done to maximize success and suggest 20 ways to profit in vermiculture in addition to selling worms.
