Vermicompost: A Six-Bed Unit's Numbers
A six-bed vermicompost unit costs about Rs 34,000 after subsidy and turns waste into a saleable product. Cost sheet, revenue, and what decides it.

Overview
Vermicompost is organic matter — dung, crop residue, farm waste — digested by earthworms into a fine, dark, earthy-smelling manure. Its NPK content is modest (roughly 1.5% N, 0.5% P, 1% K) but it is dense in micronutrients, beneficial microbes, enzymes and humus, which is where its real value lies.
It works by improving the soil, not by dumping nutrients: better structure and water-holding, more microbial life, steadier nutrient release. That makes it excellent for nurseries, vegetables and orchards, and as the backbone of an organic system — used to reduce, not entirely replace, chemical fertiliser on field crops.
What it is and when to reach for it
- A soil-building organic manure for nurseries, vegetables, orchards and organic systems — reach for it to raise organic matter and microbial life.
- Its NPK is modest, so on field crops it reduces rather than fully replaces chemical fertiliser.
- Made from farm waste, it turns a disposal problem into a low-cost input.
How to use it well
- Field crops: apply roughly 2–4 tonnes/acre, broadcast and incorporated before sowing.
- Vegetables, nurseries and pots: use more generously, mixed into the bed or potting mix; it is gentle and will not burn seedlings.
- Apply it a little before sowing so the soil life is active when the crop establishes.
Quality and common mistakes
- Good vermicompost smells earthy, is cool, dark and crumbly, and is free of un-decomposed material — not hot or foul-smelling.
- Do not treat it as a full NPK substitute on a heavy-feeding field crop; pair it with the nutrients the crop still needs.
- Avoid letting it dry out completely in storage, which kills the microbial life that makes it valuable.

Common questions
How much vermicompost per acre?
For field crops, roughly 2–4 tonnes per acre, broadcast and mixed into the soil before sowing. For vegetables, nurseries and pots you can use it more generously because it is mild and will not scorch seedlings.
Can vermicompost replace fertiliser?
On high-yielding field crops, not entirely — its NPK content is modest, so it reduces rather than fully replaces chemical fertiliser. Its strength is building soil health, structure and microbial life, which is why it is the backbone of organic and vegetable systems.
How do I know vermicompost is good quality?
Good vermicompost is dark, crumbly and cool, smells earthy (not foul), and has no recognisable un-decomposed waste in it. If it is hot, slimy or smells bad, it is not finished or has gone anaerobic.
