Organic fertilizer manufacturer: contract manufacturing and private label
Germiflor, a French manufacturer of organic and organo-mineral fertilizers, has been based in Aussillon, in the Tarn, since 1885. We manufacture under contract for other manufacturers and agricultural merchants, produce private-label products for distributors and garden centres, and develop custom formulas for farmers from their soil analysis. Your formula, with or without Mazor®, in the packaging of your choice, usually delivered within 15 days.

Contract manufacturing, private label or custom formula: our three services
Contract manufacturing means having a specialist manufacturer produce your fertilizer, to your own formula or specification, and then selling it under your own name. Germiflor offers three services, and everything is produced in its factory in the Tarn.
Contract manufacturing, for manufacturers, agricultural merchants and cooperatives: we produce your formula, whether an organic fertilizer, an organo-mineral fertilizer or a soil amendment, using your raw materials and specifications, or ours.
Private label, for distributors, garden centres and brands: finished products under your name, in printed bags or buckets, with a minimum of 25 tonnes. Depending on your project, this is either the equivalent of a product in our range, such as our Germi’One® amendment, or an exclusive formula we make for you alone. We agree exclusivity and confidentiality with you at the quotation stage.
Custom formula, for farmers: based on your farm’s soil analysis, our technical team develops a formula suited to your plots. The minimum production run is 12 to 25 tonnes, depending on the formula.
- Contract manufacturing for manufacturers, merchants and cooperatives
- Private label from 25 t
- Custom formula: 12 to 25 t minimum, depending on the formula

Making organic fertilizers since 1885
Five generations of the same family have built Germiflor, near Mazamet, into a recognized organic fertilizer manufacturer. Composting, blending, granulation and bagging: every stage of production is run by our own teams.
Lead times are indicative and vary with the season, the formula and the packaging chosen.

The fertilizers we manufacture
We manufacture organic fertilizers, organo-mineral fertilizers and organic amendments, in powder form or as 5 mm granules. We have already developed more than 600 formulas in our factory, for vines, fruit trees, vegetables, field crops, green spaces and gardens.
Each formula can include Mazor®, our patented compost, or leave it out. It can be approved for organic farming (like 93% of our range), 100% plant-based and vegan, or enriched with magnesium, sulphur, iron or potash to suit its intended use.
The regulatory status is decided at the formulation stage: a fertilizer (standard NF U 42-001), an organic amendment (NF U 44-051) and a growing medium (NF U 44-551) are subject to different rules. We help you choose the right one for your product.
Contract manufacturing in three steps
Three steps, from your request to delivery.
- 01Step 1Your specificationsFormula, raw materials, volumes
You send us your formula (or, for a custom formula, your agronomic goals and soil analysis), along with the volumes and packaging you need.
- 02Step 2FormulationCompliance and sign-off
Our technical team adjusts the formula, selects the raw materials, checks compliance with the target standard, and signs the formula off with you before production.
- 03Step 3Production and deliveryUsually within 15 days
We manufacture your product, pack it under your brand or in plain bags, then deliver it to your site. From order to delivery, it usually takes less than 15 days.

The Germis’ tip
Before launching your fertilizer brand, decide on your product’s status: fertilizer, organic amendment or growing medium. That choice determines which standard applies, how the product is labelled and what wording is mandatory. Better to settle it with us at the formulation stage than to have to reprint your bags.

Our Mazor® compost: an edge for your formulas
Germiflor is also a compost maker. Our Mazor® compost is the result of seven months of controlled composting with the patented Cronops® process: plant oilseed cakes, grape and olive pulp, coffee grounds and, depending on the formula, sterilized animal materials are transformed. Carbon is stabilized, the C/N ratio falls, pathogens are eliminated and the microflora develops. That is what sets a composted material apart from the same material in its raw state.
Added to your formula, Mazor® provides stable, living organic matter, with 1 billion micro-organisms per gram. We use it in our own products and offer it in those we make for you.
Our know-how goes back a long way: in Mazamet, wool used to be mixed with fruit pulp to make “le bourru”, one of the town’s first fertilizers. We have revived it in our Humiflor® Humomaze® amendment.

Quality and traceability: our guarantees
Our factory has an in-house laboratory and a sample library, and is approved as a composter and as a storage and blending operator (approval No. FR 81021129).
Depending on the product, our formulas can be approved for organic farming under Regulation (EU) 2018/848, 100% plant-based (vegan), USDA Organic or OMRI Listed. They can also be certified Qualité France by Bureau Veritas, like our Humiflor® Humomaze® amendment.
We bring you the same agronomic expertise we offer winegrowers, fruit growers and vegetable growers: see, for example, our vineyard fertilizer page.

Contract manufacturing: your questions
Our technical team’s answers to the questions manufacturers, distributors and farmers ask us most often.
What is fertilizer contract manufacturing?
It means having a specialist manufacturer produce your fertilizer, to your own formula or specification, and then selling it under your own name. Germiflor makes organic fertilizers, organo-mineral fertilizers and soil amendments on this basis for manufacturers, agricultural merchants, distributors and garden centres.
What is the minimum order quantity for private-label fertilizer?
The minimum is 25 tonnes per production run for private label. For a custom formula made for a farm, it ranges from 12 to 25 tonnes, depending on the formula.
Can a farmer have their own fertilizer made?
Yes. Based on your farm’s soil analysis, our technical team develops a formula suited to your plots. The minimum production run is 12 to 25 tonnes, depending on the formula.
How long does production take?
Usually less than 15 days from order to delivery. It varies with the time of year, the formula and the packaging.
Can you make a fertilizer approved for organic farming?
Yes. 93% of our range is approved for organic farming under Regulation (EU) 2018/848, and we also make 100% plant-based (vegan) formulas.
Can Mazor® be added to my formula?
Yes, and the choice is yours: we manufacture with or without Mazor®, our compost produced through seven months of composting with the patented Cronops® process.
What packaging options do you offer?
20 to 35 kg bags, printed with your brand or plain; 250 to 1,000 kg big bags; buckets for garden centres; and bulk loads of about 25 tonnes.

Both: our fertilizers and amendments are available in powder form or as granules (pellets) 5 mm in diameter.
Where is the Germiflor factory?
In Aussillon, near Mazamet, in the Tarn (Occitanie, France). We deliver to customers in mainland France and in France’s overseas departments and territories, including the French West Indies and Réunion.
Will my formula stay exclusive and confidential?
