Improves soil aerationEnriches 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 [43]Attracts deep-burrowing earthworms already present in the soilImproves water holding capacity[44]
Plant growth
Enhances germination, plant growth, and crop yieldImproves root growth and structureEnriches soil with micro-organisms (adding plant hormones such as auxins and gibberellic acid)[citation needed]
Economic
Biowastes conversion reduces waste flow to landfillsElimination 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)Creates low-skill jobs at local levelLow 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-siteLarge 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 gasemissions such as methane and nitric oxide(produced in landfills or incinerators when not composted.
