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.

Arne Grønlund Sissel HansenAbstract
The agricultural sector contributes about 9 % of the officially reported GHG emissions in Norway, and about 13 % when the estimated CO2 losses from peat and arable soils are included. N2O, CH4 and CO2 make up comparable amounts of the emissions. N2O emissions are estimated at 2.1 million tonnes (Mt) CO2 equivalents, originating in fertilizers in soil, livestock manure, runoff, N fixation, residual crops, NH3 in precipitation, and mineralisation of organic soils. CH4 emissions are calculated at 2.2 Mt CO2 equivalents, of which 85 % originates in enteric fermentation of ruminants and 15 % in farmyard manure. CO2 emissions are estimated at 2.7 Mt CO2 equivalents, and include degradation of organic soils (1.8 Mt), C loss from mineral arable soils (0.5 Mt) and fossil fuel combustion (0.4 Mt). The estimates for N2O and CO2 from soils are very uncertain.

De tre såmaskinene Väderstad Rapid, Underhaugs direktesåmaskin og Stokland ble sammenliknet av frøavlere i Telemark ved gjenlegg av grasfrøeng i falskt såbed. Stokland gav best tilslag.

Et flaskt såbed er et såbed som ikke jordarbeides kort tid før såing. Denne artikkelen gir råd som slike såbed ved etablering av grasfrøeng uten dekkvekst.

Regelen om at gjenlegg til frøeng av bladfaks, strandrør, rødsvingel, engrapp og sauesvingel skal godkejnnes om høsten før utbetaling av gjenleggstilskott praktiseres ulikt fra fylke til fylke.

The world population is expected to reach an estimated 9.2 billion by year 2050. Therefore, food production globally should increase by 70 percent in order to feed the world, while total arable land, which has reached its maximal utilization, may even decrease. Climate change adds yet another challenge to the food security problem. In order to feed the world in 2050, biotechnological advances in modern agriculture are essential. After the first green revolution, plant genetic engineering has offered a new tool to incease global crop production and this will continue to play an important role in modern agriculture to meet global challenges. To enhance crop biomass through improved agronomic traits and increase photosynthetic capacity via the chloroplast genome will be of importance in the years ahead. Chloroplast genome engineering, with several unique advantages, especially transgene containment, has made significant progress in the last two decades in various biotechnology applications including development of crops with high levels of resistance to insects, bacterial, fungal and viral diseases, different types of herbicides, drought, salt and cold tolerance, cytoplasmic male sterility, metabolic engineering, phytoremediation of toxic metals and production of many vaccine antigens, biopharmaceuticals and biofuels. Chloroplast genomes of several major crops have been transformed. These advances should promote crop productivity under a changing climate. This talk will give a brief insight into the current state of the art of plastid engineering in relation to agricultural production, especially for engineering of agronomic traits and improvement of crop biomass. The future direction of this technology and challenges for improvement of cereal crops to enhance their biomass for food security in a changing climate with special emphasis on elevated CO2 will be presented.
