Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Utfordringer, muligheter og tilnærmingsmåter for utvikling av nordnorske bygdesamfunn som gjennomgår store endringer. Vi ønsker det gode liv, med bomiljø, et levebrød og gode oppvekstvilkår. Folk sin motivasjon for å leve i bygdesamfunn. Forbrukertrender under utvikling er i favør av "bygdeprodukt". Finne lokalsamfunnets fortrinn og særpreg og bygge videre på det. Åpne og inkluderende nettverk mot omverdenen er viktig.

Kommunene er en viktig aktør for ressursforvaltning og næringsutvikling. Tverrfaglighet er et godt grunnlag for å utvikle løsninger og prosesser, og er kanskje særlig viktig i Nordområdene. Det er også viktig å søke samarbeid over landegrensene fordi mange utfordringer er like på tvers av grensene.

Prosjektet har hatt som formål å fremskaffe ny kunnskap om økotoksikologiske effekter av PFOS, PFOA og 6:2 FTS på terrestrisk miljø. Som testorganisme har vi valgt meitemark(Eisenia fetida), hvor vi har undersøkt evnen til å overleve og til å reprodusere, samt vekst av avkom fram til de er kjønnsmodne. Meitemarken har økologisk viktige funksjoner både som nedbryter av organisk materiale i jord, og som matkilde for andre jordlevende sekundærkonsumenter, gnagere og ikke minst fugl. Den gjennomtrengelige kroppsoverflaten til meitemark bidrar til at forbindelser som er delvis løst i vann lett tas opp i organismene, ogmulighetene for en oppkonsentrering av PFAS-forbindelser i meitemark har derfor også blitt undersøkt.

This project was carried out at the Bioforsk research stations Landvik (58ºN, 12 m a.s.l.) and Apelsvoll (61ºN, 250 m a.s.l.) in Norway. Two USGA-spec. golf greens; one of them including lysimeters established without organic matter or with 2% (w/w) garden compost (Green Mix) in the rootzone, were sprayed for two consecutive years with prochloraz (450 g a.i./ha), azoxystobin + propiconazole (200 + 125 g a.i./ha), or trifloxystrobin + propiconazole (187.5 +125 g a.i./ha). Iprodione (2250 g a.i./ha) was included outside the lysimeters due to space limitations. As compared to the unsprayed control treatment, none of the fungicides had any effect on Gaumannomyces graminis at the applied rates, but azoxystobin + propiconazole and trifloxystrobin + propiconazole were more efficient than prochloraz and iprodione against controlling Microdochium nivale and Typhula incarnata. Inclusion of organic matter in the rootzone enhanced tiller density and overall turfgrass quality. Traces of prochoraz or trifloxystrobin were never detected in water samples. Traces of propiconazole were also mostly below the environmental safety limit (ESL). By contrast, azoxystrobin was found to exceed the ESL of 0.90 "g/l on four occasions, the highest value being 2.15 "g/l. However, as soil organic matter efficiently prevented leaching, high concentrations were only detected in leachate from straight sand rootzones. Since azoxystrobin + propiconazole and trifloxystrobin + propiconazole had equal effect on winter diseases, the latter should be the preferred choice for preventive fungicide applications in late autumn. Use of azoxystrobin + propiconazole should be limited to greens with organic matter in the rootzone.

From 2003 to 2006, three varieties of velvet bentgrass (Agrostis canina), thirteen varieties of creeping bentgrass, nine varieties of colonial bentgrass (Agrostis capillaris), four varieties of slender creeping red fescue (Festuca rubra var. trichophylla), thirteen varieties of chewings fescue (Festuca rubra var. commutata), and one variety of annual bluegrass (Poa annua var. reptans) were evaluated for establishment rate, overall turf quality (visual merit), tiller density, color, leaf fineness, per cent living plant cover, winter injury, disease resistance, spring green-up, daily height growth, and thatch accumulation in trials on USGA-spec. putting greens at the Bioforsk research stations Landvik (58°N, 12 m a.s.l.) and Apelsvoll (61°N, 250 m a.s.l.) in south-east Norway. These experimental sites are considered representative for the southern/coastal and the northern/ continental zone of Scandinavia, respectively. The trials were mowed three times per week to 3 mm for bentgrass species and annual bluegrass and to 4.5-5.0 mm for red fescues, fertilized with easily soluble, small-grain mineral fertilizer every second week, and otherwise managed as putting greens with respect to irrigation, vertical mowing, topdressing etc. The greens were not open to regular play, but articifial wear was imposed by rolling friction-drums with golf-spikes over the trials three timers per week. On average for varieties within each species, velvet bentgrass had the highest visual merit scores at both experimental sites. Velvet bentgrass had higher density and finer leaves than any other species in the study. Along with colonial bentgrass, it also had better winter survival than creeping bentgrass, red fescue and annual bluegrass. The main disadvantage of velvet bentgrass is the rapid formation of thatch; this problem must be resolved before a general recommendation for use of velvet bentgrass on Scandinavian putting greens can be given. Next to velvet bentgrass, colonial bentgrass and creeping bentgrass were ranked as the most suitable species for golf courses in the northern/continental and southern/coastal zone, respectively. Red fescues should be preferred on golf courses not using fungicides and with limited maintenance budgets. While annual bluegrass `True Putt" cannot be recommended for putting greens in any part of Scandinavia, the ranking of varieties within each species depended, for the most part, on climatic zone. The following list of recommended varieties for putting greens has been presented to the Scandinavian Turfgrass and Environment Research Foundation:

Polycyclic musk compounds have been measured in sewage sludge and leachate from landfills world wide, verifying the precence and indicating possible levels of these compounds in different soil systems. Analysis of sewage sludge samples from Norwegian sewage disposal plants have shown levels of Galaxolide and Tonalid about 0.25-22.4 mg/kg d.w. and 0.07-3.5 mg/kg d.w. respectively (mogensen et al.). However, only few studies have been accomplished to assess the effecs of these compounds on soil ecosystems. The following tests with polycyclic musk compounds and soil living invertebrates and plants provides data about what soil concentrations required before harmful effects will be observed on the tested species.
