Vermicompost Farming in Karnataka

## Vermicompost — Black Gold from Earthworms Vermicomposting uses earthworms (primarily Eisenia fetida, red wigglers) to convert organic waste into vermicompost — a pathogen-free, nutrient-dense soil amendment. ### Process Organic materials (crop residue, vegetable waste, animal dung) are loaded into vermi-beds (concrete tanks or raised beds). Earthworms are introduced and the material is maintained at 40–60% moisture. Within 45–60 days, worms convert the material into dark, friable vermicompost. ### Nutrient Profile Vermicompost contains 1.5–2.5% Nitrogen, 1.0–1.5% Phosphorus, 1.0–2.0% Potassium, abundant micronutrients, plant-growth hormones (auxins, gibberellins), and beneficial microorganisms. ### Karnataka Context Karnataka's horticulture belt has strong vermicomposting clusters. Women's SHGs produce and sell vermicompost cooperatively. The state provides 50% subsidy on vermibeds under the Bhoosamruddhi scheme. ### Economics A 10×1m vermibed yields 500–700kg vermicompost per cycle. Four cycles per year are possible. Many farmers earn ₹30,000–50,000/year from a small-scale unit.
