Sammendrag

Denne rapporten er skrevet på oppdrag fra Landbruks- og matdepartementet (LMD). NIBIO har utredet egnethet, gjennomførbarhet og mulige løsninger for krav om en minimumsandel resirkulert fosfor ved salg av fosforholdig gjødsel, dvs. et omsetningskrav. Denne utredningen estimerer mengder av ulike resirkulerbare fosforkilder. Fosforoverskudd i enkelte regioner gitt ulike begrensninger på hvor mye fosfor som kan tilføres i jordbruket er estimert for nå-situasjon og 10 år fram i tid. Videre gir utredningen en oversikt over teknologiske og regulatoriske muligheter for å produsere gjødselvarer basert på resirkulert fosfor, samt en oversikt over innhold av uønskede stoffer i ulike typer fosforkilder. Vi gjennomførte 26 intervjuer med aktører i hele verdikjeden for gjødsel med spørsmål angående et omsetningskrav for resirkulert fosfor: Gjødselprodusenter, forhandlere, kjøpere, landbruksrådgivningen, offentlige myndigheter, og aktører innenfor transport og teknologi. I tillegg til vurderingen av egnethet og gjennomførbarhet av et omsetningskrav for resirkulert fosfor har vi også gjort en kortfattet vurdering av mulige andre løsninger for å stimulere erstatning av mineralfosfor med resirkulert fosfor. Se kapittel 10 for sammendrag og konklusjoner fra rapporten og oppsummeringer i slutten av de enkelte kapitlene for sammenfatning av resultater.

Sammendrag

Closing nutrient cycles by bio-based fertilizer products (BFPs) can improve the environmental sustainability of food systems and facilitate a more circular economy. Although the theoretical potential for nutrient recycling has been explored in detail, BFPs still seldom replace mineral fertilizer products in practice. The aim of the present study was to explore the critical enabling and limiting factors for the use of BFPs as seen from the perspective of farmers, suppliers, and civil society. To this aim, qualitative interviews were conducted with seven conventional grain farmers, six suppliers of BFPs, and five representatives of civil society, limited to environmental non-governmental organizations. The presented results illustrate a mismatch between demand and supply. On the one hand, the interviewed farmers were only interested in using BFPs if they are practical to use, balanced with respect to nutrient contents, and potentially provide the same earnings as mineral fertilizers. Positive effects for soil quality were an important driver for many of the farmers. On the other hand, the suppliers of BFPs were generally not able to offer products that fulfilled the farmers’ demands without economic losses, and they emphasized that they have faced several regulatory challenges. Representatives of regional civil society organizations expressed concern that new technical solutions could cause new environmental challenges, and that BFPs could enable further intensification of livestock production. The central-level representatives from the same NGOs, however, were positive about that BFPs can solve environmental problems. Policy instruments will be needed to increase the adoption of PFPs. Fostering BFPs’ that contribute to a sustainable agriculture is important to consider when formulating these polices.

Risk management of imported plants and seeds: possibilities for improved pest detection to prevent the introduction and spread of new pests


Plant pathogens and invertebrates harmful to plants continue to threatenfood security and natural habitats. In Norway, the responsibility of performingplant health inspections on imported plants has gradually shifted to importersof plants who are currently responsible for internal pest control and mustbe registered with the Norwegian Food Safety Authority.

Cultivating sustainable changes in livestock feed production and feeding practices (Feed&Feeding)


The project will evaluate various strategies for feed production and feeding practices to enhance the sustainability of Norway's food system and support national agricultural policy goals. These strategies include adjusting livestock diets, improving breeding and animal health, and introducing new protein sources for feed. The project will assess environmental impacts, such as land use changes, greenhouse gas emissions, soil carbon levels, nutrient balances, and biodiversity, as well as socioeconomic impacts, including food security, economic and social sustainability, and the viability of rural communities.
