A biofertiliser plant multiplies beneficial microbes in fermenters and turns them into carrier-based or liquid products for farmers. Fertiliser companies, state agriculture departments, dealers, FPOs and organic growers are the usual buyers. An experienced biofertiliser plant consultant helps you pick the right strains, formulation and scale before you commit capital. NPCS has supported industrial entrepreneurs since 1994, and our team works with you on technology, approvals and finance.

Market Demand for Biofertilisers in India
Demand for biofertilisers in India is rising because farmers want to cut chemical fertiliser use and rebuild soil health. High chemical fertiliser prices and the push for natural and organic farming add to this. Biostimulants are the fastest growing part of the range. Sales follow the kharif and rabi sowing seasons, and units are concentrated in Maharashtra, Karnataka, Tamil Nadu, Gujarat, Madhya Pradesh and Uttar Pradesh.
- Fertiliser companies looking for co-marketing partners
- State agriculture departments buying through tenders
- Dealers and FPOs supplying farmers directly
- Organic growers using seed treatment and fertigation
Biofertiliser Products You Can Make
Most new units start with nitrogen fixers such as Rhizobium and Azotobacter, because pulses and field crops buy them every season. Solubilising bacteria and NPK consortia suit dealer and tender markets. Liquid formulations and biostimulants suit buyers who want longer shelf life and horticulture sales.
- Rhizobium, Azotobacter, Azospirillum, Acetobacter
- Phosphate-, potash- and zinc-solubilising bacteria
- NPK consortia
- Mycorrhiza
- Liquid formulations
- Biostimulants (seaweed, humic, amino acids)
Biofertiliser Plant Process and Quality Control
The biofertiliser plant process starts with a mother culture from a recognised collection, which is grown into a starter culture and then fermented in sterilised media. Aeration and temperature control decide how many viable cells you get. After a count and contamination check, the broth is mixed with a sterilised carrier or a liquid formulation. Technology choice matters here: liquid products give a longer shelf life, while carrier products cost less to make. Quality is controlled at three points, namely contamination checks, final pH and moisture, and batch testing against FCO biofertiliser specifications.
- Mother culture
- Starter culture
- Fermentation in sterilised media with aeration and temperature control
- Count and contamination check
- Mixing with sterilised carrier or liquid formulation
- Curing
- Packing
- Batch testing and labelling
Raw Materials and Machinery for a Biofertiliser Plant
Your inputs are mother cultures, growth media such as molasses and yeast extract, carriers like lignite, talc or vermiculite, and packaging. Cultures come from ICAR or agricultural university labs and national microbial collections. The machines that matter most are the autoclave, laminar flow hood and SS fermenters, since sterility decides your viable counts. Batch fermenters range from 100 L to several KL.
- Autoclave
- Laminar flow hoods
- Shakers/incubators
- SS fermenters
- Boiler
- Mixers
- Pouch/bottle fillers
- Cold storage
- QC lab
Biofertiliser Plant Licence and Approvals
Biofertiliser plant licence and approvals start with business registration, then FCO registration with the State Agriculture Department. Units without inorganic chemicals fall in the White pollution category under the CPCB list, but confirm consent requirements with your State Pollution Control Board before construction. Biostimulants need separate product registration under FCO. Keep an accredited testing lab arrangement ready, since batch testing supports every registration and tender.
| Pollution category | Bio-fertiliser and bio-pesticides without inorganic chemicals: White (CPCB Jan-2025 Annexure-I S.No. 13) |
|---|---|
| HSN code | 3101 (biofertilisers); biostimulants classified by composition |
| GST | Biofertilisers: 5%; biostimulants are taxed by composition (seaweed, humic, amino-acid products), applied product-wise in the project financials |
| BIS / quality control order | No QCO; FCO specifications (biofertilisers; biostimulants under a separate FCO schedule) |
| Other licences | Registration under the Fertiliser Control Order with the State Agriculture Department; biostimulants need separate product registration under FCO; accredited testing lab |
Choosing Between Carrier and Liquid Biofertilisers
Carrier-based products need lower capital and suit dealer and tender sales, but their shelf life is short. Liquid biofertilisers last longer and fit fertigation and horticulture, though they need tighter formulation control. Capacity differs too: about 50–1,000 tonnes/year for carrier units and 50–500 KL/year for liquid. Consortium products can add value once your base strains are stable. Our team compares these routes against your budget and target buyers.
Selling Biofertilisers to Government Buyers
State agriculture departments buy biofertilisers through tenders, and these are often price-driven. Eligibility usually rests on FCO registration, accredited test results and consistent viable counts. Bidding well means costing your product carefully and keeping batch records in order. Many units balance tender volumes with dealer, FPO and organic grower sales so they don't depend on one channel.
Government Schemes and Project Finance for Biofertilisers
Demand for bio-inputs is supported by Paramparagat Krishi Vikas Yojana and the National Mission on Natural Farming, and some states subsidise biofertiliser distribution. PMEGP can help fund a smaller unit. Our reports are used for bank loans and government programmes such as PMEGP, MSME schemes, Mudra and NABARD-linked projects, subject to each lender's requirements.
What Decides Success in a Biofertiliser Plant
Good operators protect strain quality and viable counts, and they run farmer demonstrations to build trust. The main risks are listed here, along with the spent media that you must send to compost or an ETP.
- Short shelf life in carrier products
- Quality perception among farmers
- Product approvals for biostimulants
- Price-driven tenders
- Tender eligibility and shelf life

Biofertiliser Plant: Frequently Asked Questions
How much does a biofertiliser plant setup cost in India?
A biofertiliser plant typically needs about ₹50 lakh–₹5 crore, depending on capacity and technology. This is indicative and covers fermentation, formulation, lab and cold storage, but excludes land. Your project report works out the exact figure for your capacity.
Which licence and pollution category apply to a biofertiliser plant?
You need registration under the Fertiliser Control Order with the State Agriculture Department. Units without inorganic chemicals are White category under the CPCB list. Biostimulants need separate product registration under FCO, so confirm requirements before you start.
How much land and power does a biofertiliser plant need?
A unit typically needs about 0.25–2 acres of land and a power load of about 30–200 kW. Water use is moderate. Actual needs depend on whether you make carrier or liquid products and on your planned capacity.
How to start a biofertiliser plant business?
Begin by choosing your strains, formulation and capacity, then prepare a project report. Next, hire a microbiologist, register under FCO and arrange finance. Source cultures from recognised collections and plan your lab before ordering machinery.
