Vermicomposting uses worms to decompose waste and make nutrient-rich "worm manure". Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast.
The average thickness of the drilosphere (lining of an earthworm burrow) is 2 mm, [4] but it can be much wider (about 8 mm) around the burrows of litter-feeding earthworms. [ 5 ] Through the drilosphere, earthworms influence soil microbial communities, with effects on microbial processes related to soil organic matter and nutrient dynamics. [ 6 ]

Earthworms are classified into three main ecophysiological categories: (1) leaf litter- or compost-dwelling worms that are nonburrowing, live at the soil-litter interface and eat decomposing organic matter e.g. Eisenia fetida; (2) topsoil- or subsoil-dwelling worms that feed (on soil), burrow and cast within the soil, creating horizontal ...
(Savigny, 1826) [1] [2] Allolobophora chlorotica (commonly known as the green worm ) [ 3 ] is a species of earthworm that feeds and lives in soil. This species stands out from other earthworms due to the presence of three pairs of sucker-like discs on the underside of the clitellum .
Eisenia fetida, known under various common names such as manure worm, [2] redworm, brandling worm, panfish worm, trout worm, tiger worm, red wiggler worm, etc., is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil.
The European nightcrawler (Dendrobaena hortensis) is a medium-small earthworm averaging about 1.5 g when fully grown. Generally blueish, pink-grey in color with a banded or striped appearance, the tips of their tails are often cream or pale yellow. When the species has not been feeding, it is pale pink.
Eudrilus eugeniae, also called the "African nightcrawler", is an earthworm species native to tropical west Africa and now widespread in warm regions under vermicompost; it is an excellent source of protein and has great pharmaceutical potential. [1] [2]
