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 ... -

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 ...
