Effect of topography on nitrous oxide emissions from winter wheat fields in Central France
We assessed nitrous oxide (N 2O) emissions at shoulder and foot-slope positions along three sloping sites (1.6–2.1%) to identify the factors controlling the spatial variations in emissions. The three sites received same amounts of total nitrogen (N) input at 170 kg N ha −1. Results showed that lands...

► Soil inorganic N content was the major factor controlling N
