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 ]
Earthworm head. Depending on the species, an adult earthworm can be from 10 mm (0.39 in) long and 1 mm (0.039 in) wide to 3 m (9.8 ft) long and over 25 mm (0.98 in) wide, but the typical Lumbricus terrestris grows to about 360 mm (14 in) long. [9]

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]
