På 1940- og 50-tallet ble det plantet mye ny granskog i Nord-Norge. Denne skogen er nå i ferd med å bli hogstmoden. Kan den brukes?

Effektane av klimaendringane, som temperaturstigning, vil forsterke andre pågåande prosessar, som gjengroing i semi-naturlege naturtypar. Dette trugar fleire raudlista karplanter som har dette som leveområde.

Fish sludge (faeces and fish residues from farmed fish) is currently not permitted as an ingredient in CE-marked fertilising products under the EU Fertilising Product Regulation No. 2019/2009 (FPR). This report provides the scientific basis for a potential proposal to include fish sludge in the FPR by 1) summarising existing knowledge on contaminant levels and the agronomic efficiency, and 2) identifying knowledge gaps. The legal status of fish sludge under the Animal by-products regulation (EU) No. 1069/2009 (ABP) has to be clarified first but is outside the scope of the report. Most available data on fish sludge originate from land-based Atlantic salmon production in Norway. A major knowledge gap is therefore the lack of data on contaminant levels and the agronomic efficiency of fish sludge from sea-based systems, as well as from other countries and aquaculture species. With respect to contaminant levels in fish sludge from land-based smolt systems in Norway, additional data are required for hexavalent chromium, inorganic arsenic, pharmaceuticals, and certain pesticides. The agronomic efficiency of fish sludge from land-based smolt systems in Norway is relatively well documented.

Bio-based fertilizers (BBFs) are part of the circular economy model for Europe to achieve climate neutrality by 2050, decoupling economic growth from resource exhaustion and maintain agronomic production within planetary boundaries. Here, an Ecotron experiment evaluated agronomic performance and greenhouse gas (GHG) emissions (N 2 O, CO 2 ) of four BBFs compared to a synthetic fertilizer (SYN) in broccoli production under a historic reference and a future RCP8.5 climate scenario for Belgium. Crop production parameters such as element use efficiencies and yield were similar or lower for plants receiving BBFs compared to SYN in the reference climate, but similar or higher for BBFs compared to SYN in the future climate. Mechanistically, cropping systems with BBFs benefited from enhanced soil microbial activity compared to SYN in both climates (measured as hydrolysis of fluorescein diacetate), but concurrently also had higher GHG emissions. The risk of nitrate leaching was indifferent amongst fertilizers but globally increased in the future climate with more intense dry-rain shifts. While these results support BBFs as agronomic alternatives to SYN, further research is needed to address climate-induced yield penalties which were observed for all fertilizers (BBFs & SYN) in the future climate.

Background and aims Drought weakens tree defenses, predisposing Norway spruce (Picea abies) to spruce bark beetle (Ips typographus) attack. The extreme 2018 summer drought in Sweden triggered an unprecedented bark beetle outbreak. Our objective was to quantify how weather, soil moisture, and tree provenance influence Norway spruce defense capacity to a necrotrophic beetle-associated pathogen. Methods Trees at three sites in Sweden were inoculated with the phytopathogenic fungus Leptographium europhioides on four occasions during each of the 2019 and 2021 growing seasons. At each site, we inoculated spruce provenances of Swedish or East European origin, with early and late spring bud burst, respectively. Tree defense capacity, expressed as the extent of necrotic lesion formation following fungal inoculation, was used as a proxy for resistance to bark beetle attack. Results Spruce defense capacity (i.e. lesion size) differed with water availability (both precipitation and soil moisture conditions) but not with the timing of spring bud burst. There were within-season differences, with trees having less efficient defenses (producing larger lesions) in the early season (June). On intermediate soil moisture sites, lesions were larger in 2019 than in 2021. In both years, there was a significant negative correlation between lesion size and water availability in the autumn of the previous year. Conclusion Spruce defense capacity varied with local environmental conditions but not with provenance phenology. Variations between study years reflected the sensitivity of spruce defenses to climatic variability and the partial recovery of tree resistance 3 years after the 2018 drought.
