      Extreme climatic events, such as droughts and heat stress, induce anomalies in ecosystem–atmosphere CO2 fluxes, such as gross primary production (GPP) and ecosystem respiration (Reco), and, hence, can change the net ecosystem ...

    • 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 ...
