We work hand-in-hand with farmers to develop innovative cropping systems in conservation agriculture. Our approach is based on a participatory and iterative process where experts and researchers are directly involved. On-farm experiments made in a systemic approach are carried out in 17 pilot farms in the South of France. Many other farms are involved through their participation in the co-conception process (plenary meetings, on-farm visits, technical days...) and through trainings on diverse themes (soil conservation techniques, soil health, relations between soil, plants and cattle, bio-indicator plants...) proposed by ADAF during winter.
