Vermicompost contains water-soluble nutrients and is an excellent, nutrient-rich organic fertilizer and soil conditioner. It is used in farming and small scale sustainable, organic farming.
Vermicomposting can also be applied for treatment of sewage. A variation of the process is vermifiltration (or vermidigestion) which is used to remove organic matter, pathogens and oxygen demand from wastewater or directly from Blackwater of flush toilets
BENEFITS
Soil
- Improves soil aeration
- Enriches soil with micro-organisms (adding enzymessuch as phosphatase and cellulose)
- Microbial activity in worm castings is 10 to 20 times higher than in the soil and organic matter that the worm ingests
- Attracts deep-burrowing earthworms already present in the soil
- Improves water holding capacity[45]
Plant growth
- Enhances germination, plant growth, and crop yield
- It helps in root and plant growth
- Enriches soil with micro-organisms (adding plant hormonessuch as auxins and gibberellic acid)
Economic
- Bio wastes conversion reduces waste flow to landfills
- Elimination of bio wastes 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 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
- Production reduces greenhouse gasemissions such as methane and nitric oxide (produced in landfills or incinerators when not composted).
