Experimental Farms for Regenerative Agriculture Research
In 2026, the R&D department has structured a network of experimental farms dedicated to regenerative agriculture research.
Why set up experimental farms?
Regenerative agriculture relies on a holistic, farm-scale approach to crop rotations and long-term planning.
However, traditional R&D methods, based on field-scale trials conducted over a single growing season, do not allow for a full understanding of interactions between different practices and long-term effect.
Experimental farms enable us to test our innovations in micro-plots and then conduct large-scale trials under real conditions, using farmers’ equipment, in order to validate benefits and scalability..
Partner farmers at the heart of the system
The network is composed of 9 farms, spread from the Landes region to Normandy (France), representing diverse soil and climate conditions and cropping systems.
These farms were selected for their long-standing commitment to conservation agriculture (CA) or simplified cultivation techniques (SCT), some for over 30 years.
Their expertise is a key driver for developing solutions tailored to real-world conditions.
Three R&D programs deployed within the network
The research conducted on the farms is structured around three main programs:
- Developing solutions that combine agronomy and genetics to support the transition of maize and sunflower. As an exemple, the COMPAMAÏS program focuses on combination of maize varieties and companion plants.
- Developing cover crops and forage mixtures, with a strong focus on how they fit into rotations, adapt to soils, and impact the following crops.
- Running maize and sunflower varietal trials to identify which genetics perform best under regenerative farming conditions.
“In 2026, the goal is to establish the foundations of a working relationship with each farmer participating in the program.In 2027, the aim will be to foster the network in order to encourage the exchanges between farmers, the sharing of experiences, and collective learning around the innovations being tested.”
Marie Boncompain, R&D Project Manager

As farming conditions become increasingly unpredictable, we believe plant breeding must anticipate tomorrow’s challenges rather than simply respond to today’s. By combining genetics, environmental modelling, advanced phenotyping and data science, we develop reliable varieties that help farmers maintain performance in changing conditions. Breeding for the field of tomorrow To build resilient crops, we start by […]
