Vermicompost is the product of composting utilizing various species of worms, and earthworms to create a heterogeneous mixture of decomposing vegetable (produced from the aquaponics plant). The vermiculture plant would be placed next to the aquaponics plant and all unused or waste plant material from the hydroponics plant would provide food for the worm farm. Worms would feed off the waste generated from the hydroponics plants. The worms in turn produce vermicast. Vermicast, also known as worm castings, worm humus or worm manure which is used as a manure or fertiliser.
Worms have a number of other possible uses including their value as a high-quality animal feed. Vermicomposting and Vermiculture therefore offer organic farmers the opportunity to further supplement their income from this source.
Vermiculture is the culture of earthworms. The goal is to continually increase the number of worms in order to obtain a sustainable harvest. The worms are either used to expand a vermicomposting operation or sold to customers who use them for the same or other purposes.
Vermicomposting is the process by which worms are used to convert organic materials (usually wastes) into a humus-like material known as vermicompost. The goal is to process the material as quickly and efficiently as possible. These two processes are similar but different. If your goal is to produce vermicompost, you will want to have your maximum worm population density all of the time. If your goal is to produce worms, you will want to keep the population density low enough that.
