Abstract: Organic agriculture is widely acknowledged as a strategy to reduce the environmental impacts of food production while helping achieving global climate and biodiversity targets. Yet, recent global studies and meta-analyses have highlighted the strong nitrogen (N) limitation of many organic cropping systems. Sustaining crop yields thanks to biological N fixation (BNF) in organic cropping systems is key. However, we lack a systematic estimate of BNF operated by legume crops under organic management, and how it varies according to crop species and cropping practices.
