How We Calculate Vermicompost Production
📋 Processing Steps
💡 Maintenance Tips
• Maintain moisture at 60-70% (should feel like a squeezed sponge)
• Keep temperature between 20-30°C
• Protect from direct sunlight and rain
• Avoid adding citrus peels, meat, dairy, or oily food
• Add waste in layers (2-3 inches thick)
• Cover with wet gunny bags or jute
• Turn bedding every 10-15 days gently
• Check pH - should be 6.5-7.5
• Ensure proper aeration (punch holes if needed)
• Watch for pests (ants, centipedes) and remove
• Harvest when compost is dark brown and granular
• Separate worms by heap method or light exposure
• Store in cool, dry place in bags
• Earthworms multiply - 1 kg becomes 3-4 kg in 3 months
