Learn everything about vermicomposting in India—methods, benefits, success stories, business potential, and government schemes. Discover how farmers and entrepreneurs can turn waste into wealth with this eco-friendly practice.
Introduction
India, an agrarian economy with millions dependent on farming, faces
challenges such as soil degradation, reduced fertility, and rising dependence
on chemical fertilizers. Amid these challenges, vermicomposting has
emerged as a sustainable, cost-effective, and eco-friendly alternative.
Vermicomposting is the process of converting organic waste into nutrient-rich
compost using earthworms. The result is called vermicast or vermicompost,
often referred to as “green gold” for its ability to rejuvenate soil health and
boost crop productivity.
In
this blog post, we will cover everything about vermicomposting in India: its
significance, methods, benefits, business potential, government support, and
practical steps for setting up a unit.
What is Vermicomposting?
Vermicomposting is the biological decomposition of organic waste
using earthworms. Unlike traditional composting, which relies solely on
microbial activity, vermicomposting leverages worms to accelerate the process
and enrich the compost. Earthworms consume organic material and excrete
nutrient-rich castings, improving soil structure and fertility.
Importance
of Vermicomposting in India
1.
Soil Health Restoration: Indian soils are losing fertility due to overuse of chemical
fertilizers. Vermicompost restores organic matter and improves soil texture.
2.
Waste Management: India produces nearly 62 million tonnes of municipal waste
annually, much of which is organic. Vermicomposting offers an eco-friendly
waste disposal method.
3.
Sustainability: It reduces dependency on chemical inputs, lowers greenhouse gas
emissions, and promotes sustainable farming.
4.
Economic Opportunities: Vermicomposting creates income opportunities for farmers,
entrepreneurs, and self-help groups.
Earthworm Species Used in Vermicomposting
Not all earthworms are suitable for composting. The following
species are widely used in India: - Eisenia foetida (Red Wiggler):
Highly efficient, fast breeder. - Eudrilus eugeniae (African
Nightcrawler): Produces high-quality compost. - Perionyx excavatus
(Indian Blue Worm): Native to India and highly adaptable. - Lampito mauritii:
Indigenous and used in some traditional composting systems.
Methods of Vermicomposting in India
There are two main methods of vermicomposting commonly used in
India:
1. Pit Method
·
Construct cement or brick pits
of 5×5×3 feet.
·
Ensure proper drainage and
ventilation.
·
Spread sand or broken bricks at
the bottom.
·
Add loamy soil, organic waste,
and cow dung.
·
Introduce earthworms and keep
moist.
2. Bed or Vermibed Method
·
Prepare beds measuring 2×1×0.75
meters.
·
Lay polythene sheets or use
bamboo/earthen beds depending on local conditions.
·
Add layers of organic waste and
cattle dung.
·
Introduce earthworms and keep
moist under shade.
This method is
cheaper and widely practiced in rural India.
Steps to Set Up a Vermicompost Unit
1.
Site Selection: Choose a shady and moist area, protected from direct sunlight and
rain.
2.
Bed Preparation: Spread a layer of sand (2–3 inches), followed by loamy soil.
3.
Feeding: Add pre-decomposed organic matter such as cow dung, crop residues,
and kitchen waste.
4.
Earthworm Introduction: Add around 1 kg of earthworms per 100 kg of organic waste.
5.
Moisture Maintenance: Keep moisture at 40–50% by sprinkling water. Avoid excess water.
6.
Protection: Cover with gunny bags or dry leaves to maintain temperature and
humidity.
7.
Harvesting: Compost is ready in 60–90 days. It appears dark, crumbly, and
earthy.
8.
Separation: Stop watering 2–3 days before harvest. Worms move down, and
compost can be collected.
Applications of
Vermicompost
1.
Field Crops: Applied at 2–4 tonnes per hectare.
2.
Fruit Trees: 5–10 kg per tree.
3.
Vegetables: 500–750 kg per acre.
4.
Flowers and Ornamentals: Enhances flowering and color vibrancy.

for compost units. - Rashtriya Krishi Vikas Yojana (RKVY-RAFTAAR):
Supports startups and farmers. - Mission for Integrated Development of
Horticulture (MIDH): Encourages use of organic inputs.
Farmers can avail subsidies up to ₹10,000 for setting up
vermicompost pits.
