Abstract:
At the Rothamsted Research Woburn farm near Woburn, east of England (loamy sand topsoil texture), direct nitrous oxide emissions were measured from replicated (x3) plots (10 x 6 m) following spring applications of manufactured nitrogen (N) fertilisers to winter wheat. A control treatment was included where no N fertiliser was applied. Ammonium nitrate (AN) fertiliser (34.5% N) was applied at 5 different rates; 60, 120, 180, 240 and 300 kg N/ha, and urea fertiliser (46% N) at a rate of 180 kg N/ha, in three split applications (mid-March, early-April and early-May). In separate AN and urea treatments, a commercially available nitrification inhibitor was tested; dicyandiamide (DCD) was sprayed at a rate equivalent to 10 kg DCD/ha onto the plots immediately after each N fertiliser application. The N supplied by the DCD was accounted for in the total N application of 180 kg N/ha, which was applied in three splits. A DCD only treatment was also included, where DCD was sprayed onto the soil surface in three split applications giving a total N application of 20 kg/ha. Additionally, AN fertiliser was also applied in five equal splits in mid-March, early-April, late-April, early-May and late-May i.e. ‘little and often’. This dataset contains daily rainfall (mm), daily maximum air temperature (degree Celsius) and daily minimum air temperature (degree Celsius) measured from either the closest meteorological station to the experimental site or from instruments located at the experimental site. Weather data is available for the experimental measurement period only. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
