Carbon sequestration in grassland under German fertiliser regulations

Carbon sequestration in grassland is affected by Germany's new Fertiliser Ordinance, which strengthens requirements for fertiliser use and product labelling to ensure compliance. Various recycling and upcycling methods for farm fertilisers are under evaluation, with the Witte plant's composting technology for manure showing innovation but limited scalability. Challenges include logistics costs, regulatory hurdles, and unclear definitions of fertiliser versus waste. While the technology offers partial benefits, a comprehensive, multi-stakeholder approach involving experts, practitioners, and policymakers is essential to reduce nutrient inputs and address regional fertiliser surpluses effectively.
