Vermiculture biotechnology involves several steps: 1) selecting an appropriate site and earthworm species, 2) preparing the vermibed and feedstock, 3) inoculating earthworms into the bed, 4) feeding and watering the earthworms, and 5) harvesting the finished vermicompost. Some key factors in site selection include a thatched roof, transport facility, and cool, shady area. Common methods of vermicomposting include pit, heap, bin/tray, windrow, and wedge techniques.
