Frøseth, Randi Berland; Bakken, Anne Kjersti; Bleken, Marina Azzaroli; Riley, Hugh; Pommeresche, Reidun; Thorup-Kristensen, Kristian; Hansen, Sissel (Journal article; Peer reviewed, 2014) -
Klimatiltak i jordbruket - mindre lystgassutslipp gjennom mindre N-tilførsel til jordbruksareal og optimalisering av dyrkingsforhold
Øygarden, Lillian; Nesheim, Lars; Dörsch, Peter; Fystro, Gustav; Hansen, Sissel; Hauge, Atle; Korsæth, Audun; Krokann, Knut; Stornes, Ole Kristian (Bioforsk Rapport, Research report, 2009)I denne rapporten er det gjort vurderinger av tiltak for bedre utnyttelsen av nitrogen tilførsel til jordbruksareal- mer effektiv og presis nitrogengjødsling. Bedre nitrogenutnyttelse gir risiko for mindre tap og dermed ... -

Nadeem, Shahid; Hansen, Sissel; Bleken, Marina Azzaroli; Dörsch, Peter (Journal article; Peer reviewed, 2012) -
Nitrogen dynamics in an organic green manure - cereal rotation and mineralization of clover leaves at low temperature
Frøseth, Randi Berland (PhD Thesis;2016:25, Doctoral thesis, 2017-07-12)In northern temperate regions, grass-clover green manure leys are commonly used as a break crop in stockless organic cereal rotations in order to provide soil fertility and reduce the pressure of weeds, pests and diseases, ... -

Frøseth, Randi; Bakken, Anne Kjersti; Bleken, Marina Azzaroli; Riley, Hugh; Thorup-Kristensen, Kristian; Hansen, Sissel (Journal article, 2012) -
Predicting field N2O emissions from crop residues based on their biochemical composition: A meta-analytical approach
Abalos, Diego; Rittl, Tatiana Francischinelli; Recous, Sylvie; Thiébeau, Pascal; Topp, Cairistiona F. E.; van Groenigen, Kees Jan; Butterbach-Bahl, Klaus; Thorman, Rachel E.; Smith, Kate E.; Ahuja, Ishita; Olesen, Jørgen E.; Bleken, Marina Azzaroli; Rees, Robert M.; Hansen, Sissel (Journal article; Peer reviewed, 2022)Crop residue incorporation is a common practice to increase or restore organic matter stocks in agricultural soils. However, this practice often increases emissions of the powerful greenhouse gas nitrous oxide (N2O). ... -
Reviews and syntheses: Review of causes and sources of N2O emissions and NO3 leaching from organic arable crop rotations
Hansen, Sissel; Frøseth, Randi Berland; Stenberg, Maria; Stalenga, Jarosław; Olesen, Jørgen E.; Krauss, Maike; Radzikowski, Paweł; Doltra, Jordi; Nadeem, Shahid; Torp, Torfinn; Pappa, Valentini; Watson, Christine A. (Journal article; Peer reviewed, 2019)The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) from agricultural cropping systems have considerable negative impacts on climate and the environment. Although these environmental burdens are less per ... -
Variations in nitrogen utilisation on conventional and organic dairy farms in Norway
Koesling, Matthias; Hansen, Sissel; Bleken, Marina Azzaroli (Journal article; Peer reviewed, 2017)Reduced N-surpluses in dairy farming is a strategy to reduce the environmental pollution from this production. This study was designed to analyse the important variables influencing nitrogen (N) surplus per hectare and per ... -
Økologisk mjølkeproduksjon uten kraftfôr/Organic dairy milk production with no concentrate supplementation
Adler, Steffen Andreas; Ebbesvik, Martha; Hansen, Sissel; Granås, Rune; Lindås, Anitra; Steinshamn, Håvard (NIBIO Rapport;, Research report, 2018)Det er økende interesse hos forbrukere for mjølk og mjølkeprodukt som er produsert uten bruk av kraftfôr med bare beite og konservert gras i fôrrasjonen. Rørosmeieriet AS, som foredler økologisk produsert mjølk, er interessert ...
