vermicompost / vermi composting

A means of creating compost out of worm castings (droppings) produced by a specific species of worms [for example red wigglers]. The worms are normally kept in a 'worm farm' and fed vegetable offcuts and other organic (kitchen) waste (generally not dairy/meat/citrus) which the worms process through digestion and defecation producing a nutrient rich compost. A liquid termed 'worm tea' is also a (watered down) bi-product of vermicomposting also used by some as a liquid 'food' for growing plants/vegetables.
