Vermicompost is the product or process of composting using various worms, usually red wigglers, white worms, and other earthworms to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast. Vermicast, also called worm castings, worm humus or worm manure, is the end-product of the breakdown of organic matter by an earthworm.[1] These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than do organic materials before vermicomposting.[2]
Containing water-soluble nutrients, vermicompost is an excellent, nutrient-rich organic fertilizer and soil conditioner.[3] This process of producing vermicompost is called vermicomposting.

Benefits

Soil
• Improves soil aeration
• Enriches soil with micro-organisms (adding enzymes such as phosphatase and cellulase)
• Microbial activity in worm castings is 10 to 20 times higher than in the soil and organic matter that the worm ingests [27]
• Attracts deep-burrowing earthworms already present in the soil
• Improves water holding capacity[28]
Plant growth
• Enhances germination, plant growth, and crop yield
• Improves root growth and structure
• Enriches soil with micro-organisms (adding plant hormones such as auxins and gibberellic acid)[citation needed]
Economic
• Biowastes conversion reduces waste flow to landfills
• Elimination of biowastes from the waste stream reduces contamination of other recyclables collected in a single bin (a common problem in communities practicing single-stream recycling[29])
• Creates low-skill jobs at local level
• Low capital investment and relatively simple technologies make vermicomposting practical for less-developed agricultural regions
Environmental
• Helps to close the “metabolic gap” through recycling waste on-site
• Large systems often use temperature control and mechanized harvesting, however other equipment is relatively simple and does not wear out quickly[citation needed]
• Production reduces greenhouse gas emissions such as methane and nitric oxide (produced in landfills or incinerators when not composted or through methane harvest)[30]
