Abstract:
At Rothamsted Research, North Wyke, near Okehampton, south-west England (clay loam topsoil texture), direct nitrous oxide (N2O) and ammonia (NH3) emissions were measured from replicated (x3) plots (12 x 13 m) following spring applications of manufactured nitrogen (N) fertilisers to grassland. A control treatment was included where no N fertiliser was applied. Ammonium nitrate (AN) fertiliser (34.5% N) or urea fertiliser (46% N) was applied at a rate of 120 kg N ha-1 in two equal split applications (mid- and late April), with or without the commercially available nitrification inhibitor - dicyandiamide (DCD). The DCD was applied in a solution (15 kg DCD ha-1) and sprayed onto the plots immediately after N fertiliser application. The N supplied by the DCD was accounted for in the 120 kg N ha-1. As separate treatments, AN and urea fertiliser were also applied in four equal splits, 1 week apart from mid-April to early 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. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
