A protected production system
Amplification of local mycorrhizal communities in controlled conditions, using a proprietary biotechnology.
Amoterra R&D
465 million years of symbiosis, put back to work.
Amoterra does not propose a disruptive technology. We put back to work a symbiosis that's 465 million years old, with contemporary tools that let us characterise, amplify and measure it.
Arbuscular mycorrhizal fungi (AMF)
What is the mycorrhizal symbiosis, the Wood Wide Web, and why 80 % of land plants depend on it.

What we don't (yet) know how to do

AMF: the oldest outsourcing in the world
For 465 million years, plants have outsourced to microscopic fungi what they cannot do: explore, solubilise, transport. In return, the plant provides up to 20 % of its photosynthesis sugars. 80 % of terrestrial plants still live by this symbiosis today.
The MYCOTERROIR protocol - 6 steps
Sampling
Soil and root samples are collected on the plot following a standardised protocol.
Characterisation
DNA and microscopy-based identification of the mycorrhizal fungi present on the site.
Species extraction
Selective extraction of spores and hyphae from viable local mycorrhizal species.
Amplification
Amplification of the extracted communities in controlled conditions until a usable mass is reached.
Formulation
Packaging the inoculum into a formulation suited to the intended application method.
Application
Application in the field during optimal windows — as close to the root as possible.
The technology
The MYCOTERROIR® technology
MYCOTERROIR® technology is the result of 7 years of R&D - the only service in France to amplify terroir mycorrhizal communities.
MYCOTERROIR® rests on:
- A national mycorrhizal reference built in-house from the Amoterra database in constant evolution.
- Amplification of local mycorrhizal communities based on an exclusive, unique and protected biotechnology.
- Innovative formulations adapted for the application of mycorhizal communities.
The Amoterra reference
To qualify the mycorrhizal status of soil - a proprietary database enriched with every project.

Transparency
What we don't (yet) know how to do
MYCOTERROIR does not replace a pathogen diagnosis: for biotic disease problems, a different service applies.
On highly contaminated soils (high heavy metals, persistent pollution), mycorrhizal reintroduction alone is not sufficient. We will say so.
On some conventional intensive agriculture protocols, the persistence of biological install is compromised by existing practices. We flag this before purchase.
We say what we know and what we don't. That is the posture that makes our words tenable.

The mycorrhizal signature of terroir
The work led by Amoterra between 2019 and 2023 on terroir mycorrhizal communities has shown that every terroir has its own unique and specific mycorrhizal community, adapted to local soil, climate, crop and farming-history conditions.
Every terroir has its own mycorrhizal community: unique, specific, adapted to local soil, climate and crop conditions. That adaptation delivers:
- a stronger effect of fungal action,
- better long-term development of the symbiosis.
Local origin of the fungi
Adapted to their environment: soil, climate, host plants, history of practices.

Greater species diversity
More services delivered to plants: nutrition, water, defence, soil structure.
