Vermicompost Bed Setup: Earthworm Species, Care and Output

Bed design and setup essentials

• Types of beds: Portable UV-stabilized HDPE vermibeds fitted with aeration net windows and drainage outlets, or permanent brick masonry pits.
• Dimensions: Standard HDPE beds typically measure 12 ft length × 4 ft width × 2 ft height, allowing convenient layering and harvesting.
• Drainage and shading: Position beds on a gentle slope under thatch shading or green agro-netting to protect earthworms from direct rain and solar heat.

Raw materials, layering, and earthworm species

• Earthworm species: Eisenia fetida (red wigglers) or Eudrilus eugeniae (African nightcrawler), prized for voracious feeding and high reproduction rates.
• Bed layering: Base layer of dry straw or coconut coir (3 to 4 inches), followed by pre-decomposed farmyard manure mixed with chopped crop residues.
• Moisture and temperature: Maintain moisture at 60 to 70 percent with regular sprinkling of water, keeping bed temperatures between 20 and 30 degrees Celsius.

Harvesting vermicompost and vermiwash

• Compost maturity: Dark brown, granular, tea-powder-like castings mature within 60 to 90 days after earthworm release.
• Harvesting technique: Stop watering 3 to 4 days prior to harvest to encourage worms to migrate downward, allowing gentle scraping of top casting layers.
• Vermiwash collection: Collect nutrient-rich liquid runoff from the bottom drainage outlet for use as a foliar biostimulant.
