How to foster mycorrhiza? From brakes to levers

Agroecology aims to design economically and environmentally efficient cropping systems, based on the exploitation of natural regulations. Arbuscular mycorrhiza are of growing interest for such an ecologization of agriculture, as they are likely to provide ecosystem services and enhance crop health and productivity, reducing the use of chemicals. Agroecology no longer offers one-stop solutions but calls for a diversity of solutions that leaves the choice to farmers to build their own trade-offs, relying on their own knowledge, scientific knowledge and available products.
