Effect of calcareous and siliceous amendments on N2O emissions of a grassland soil
Todorcic Vekic, Teodora; Nadeem, Shahid; Molstad, Lars; Martinsen, Vegard; Hiis, Elisabeth Gautefall; Bakken, Lars; Rütting, Tobias; Klemedtsson, Leif; Dörsch, Peter (Peer reviewed; Journal article, 2023-05-19)Liming of acidic agricultural soils has been proposed as a strategy to mitigate nitrous oxide (N2O) emissions, as increased soil pH reduces the N2O/N2 product ratio of denitrification. The capacity of different calcareous ... -
N2O emission from organic barley cultivation as affected by green manure management
Nadeem, Shahid; Hansen, Sissel; Bleken, Marina Azzaroli; Dörsch, Peter (Journal article; Peer reviewed, 2012)Legumes are an important source of nitrogen in stockless organic cereal production. However, substantial amounts of N can be lost from legume-grass leys prior to or after incorporation as green manure (GM). Here we report ... -
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, 2019-07-17)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 ... -
Variation in rate of phenological development and morphology between red clover varieties: Implications for clover proportion and feed quality in mixed swards
Nadeem, Shahid; Steinshamn, Håvard; Sikkeland, Elin Halvorsen; Gustavsson, Anne-Maj; Bakken, Anne Kjersti (Journal article; Peer reviewed, 2019-05-28)Red clover (Trifolium pratense) grown in mixtures with grasses often constitutes a lower proportion of total yield in spring than in summer growth. A more even red clover proportion between the harvests would benefit forage ...
