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.

The project aims to create a European network of relevant stakeholders within the marine macroalgae sector, by creation of business tools such as database, website, trade directory and training materials. The network will include primary producers, processors, technology suppliers, process consultants, research institutes, development agencies, local governments and relevant community groups and other stakeholders. A wide ranging policy study will establish a best practice model and suggest policies for the successful and sustainable commercial utilization of marine macroalgae resources. The project runs from 2010-2012, and is financed by the Atlantic Area Transnational Programme, The European Regional Development Fund and by national co- funding. The project is lead by Indigo Rock Marine Research Ltd., Ireland. Partners are Bord Iascaigh Mhara (Ireland), Syndicat Mixte Pour l´Équipement du Littoral, Fisheries and aquatic sciences center- AGROCAMPUS OUEST and Université de Bretagne Occidentale (France), BIOFORSK (Norway), Universidade do Algarve (Portugal), Mutrikuko Institutua, Ikaslan Gipuzkoa and TKNIKA (Spain) and Viking Fish Farms, Ardtoe Marine Laboratory, UK. This poster will present the NETALGAE project, its aims, objectives, partners and preliminary results.

I forbindelse med anlegg av E16 gjennom Bærum, ble det inngått en avtale mellom en grunneier på Bjørum, Bærum og Statens vegvesen (SV) om oppfylling av et gammelt deponi på ca. 6 daa med omlag 100 cm leirjord slik at arealet kan benyttes til kornproduksjon. For å sikre seg at arbeidet som ble gjort på stedet holder mål med tanke på bruk av arealet til korn, fikk Bioforsk oppdrag fra Statens Vegvesen om å undersøke og uttale seg om de faktiske forholdene med tanke på kornproduksjon. Jorddybden på 15 punkter i feltet ble målt og jordprøver tatt ut til kjemiske og mekaniske analyser. Resultatene dannet grunnlaget til denne rapporten.

The marked for cereal cover crop straw and herbage seed straw has diminished in many seed production areas due to less lifestock. Seed growers therefore want to chop and return the straw both in the sowing year and in the seed harvest years. The objectives of this research were (1) to compare decomposition rates of straw of barley and wheat cover crops and timothy (Phleum pratense L.), meadow fescue (Festuca pratensis Huds.), and red clover (Trifolium pratense L.) seed crops, (2) to study the effect on soil microbial activity of adding mineral nitrogen or fresh leaves from undersown seed crops, and (3) to evaluate the effect of straw placement / soil contact on straw decomposition rates. Microbial activity / straw decomposition rates were evaluated by regular measurement of CO2 production in four laboratory incubation experiments lasting for 150-161 days. Microbial activity was always enhanced by adding straw on the soil surface. Straw of barley resulted in higher CO2 production than straw of wheat, while straw of red clover and meadow fescue resulted in higher CO2 production than straw of timothy. Inclusion of fresh leaves of white clover and timothy increased CO2 production during the first and second half of the incubation experiments, respectively. Neither in the sowing year nor in the seed harvest year was microbial activity stimulated by adding fertilizer nitrogen, but soil mineral nitrogen by the end of the experiments was higher after adding fertilizer or fresh leaves, and lower after adding grass seed straw. Presumably due to higher humidity, straw decomposition in a field experiment was higher in timothy stubble than in wheat stubble and higher at 2 cm than at 10 cm above the soil surface. For practical seed production, growers are recommended to leave short stubble, to chop the straw as finely as possible, and to distribute the straw evenly on the surface in close contact with soil particles.

Three different seed vigour tests, Accelerated ageing (AA), Germination index (GI) and Polyetylenglycol (PEG), were evaluated with regard to ranking six reference seed lots of ‘Grindstad" timothy (Phleum pretense L.) and ‘Lea" red clover (Trifolium pratense L.) according to their physiological potential for storage. The seed reference lots, which all had equally high standard germination percentages, had sustained different degrees of ageing before examination. In timothy, both the AA-test and the GI-test managed well to separate the low-vigour seed lots, having a poor storage potential, from the high-vigour seed lots with better storage longevity. The clearest separation was obtained using the GI-test, either as complete test (six out of six seed lots was significantly separated) or as a simplified test (five out of six seed lots was significantly separated). The germination index of the two tests was based on counting of germinating seeds either on a daily basis for ten days or after counting on day 3 and day 5, respectively. Also the AA-test managed to separate five out of six seed lots of timothy after optimal treatment for 56 h at 45oC. In red clover, the AA-test gave the clearest separation between seed lots. At optimal conditions for 24 h at 45oC, as many as five of the six red clover seed lots could significantly be separated from each other. The recommended seed vigour test for timothy (GI-test) and red clover (AA-test for 24 h at 45oC) has later been adopted for use in practical seed testing routines at the Norwegian National seed laboratory.

De meteorologiske målingene på værstasjonen til Bioforsk Landvik i Grimstad viste en årsmiddeltemperatur for 2009 på 7,6 °C, som er 0,7 °C over normalen på 6,9 °C. Den totale nedbørsmengden i løpet av året ble hele 1703 mm, som er 39 prosent mer enn årsnormalen på 1230 mm.
