In this talk, Kristen Sukalac introduces how Prospero and Partners supports the plant biostimulants and the organic-based fertilizer industries through the respective associations that Prospero co-founded with the sectors and has run ever since: the European Biostimulants Industry Council (EBIC) and the European Consortium of the Organic-based Fertilizer Industry (ECOFI). She then gives an overview of the EU Fertilising Products Regulation (FPR) and the prospects for blue-green algae to be covered.
