The EU Farm to Fork and Biodiversity Strategies have set a goal of 25% organically farmed area in 2030. This relies on sufficient nitrogen to sustain productivity, while emissions of nitrogen are minimized to prevent climate and environmental impacts. Increased recycling of nitrogen at field, farm and system levels is key to this transition, and aligns well with the principle of ecology of organic farming. This special session focuses on recent advances in research, innovation, and development of policies that contribute to solve the challenges of nitrogen supply and management in organic farming systems. We welcome diverse contributions reaching from microbial processes to crops, animals and systems to improve recycling, increase availability and reduce losses of nitrogen.

In this session, we will:

• Share new science and advance our understanding of challenges of nitrogen in organic farming

• Engage in oral and poster presentations

• Explore solutions and perspectives through multi-stakeholder discussion
