Abstract:
On a commercial arable farm near Cambridge, eastern England (clay topsoil texture), direct nitrous oxide (N2O) and ammonia (NH3) emissions were measured from replicated (x3) plots (24 x 11 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), urea fertiliser (46% N) or an ammonium sulphate nitrate (ASN) fertiliser (26% N) were applied at a rate of 200 kg N/ha, in three split applications (mid-March, mid-April and early-May). In separate treatments, two commercially available nitrification inhibitors were tested; dicyandiamide (DCD) was sprayed at a rate of 10 kg/ha (6.5 kg N/ha) onto the AN and urea plots immediately after N fertiliser application, and a 3,4-dimethylpyrazole phosphate (DMPP) containing fertiliser (26% N) was also applied at a rate of 200 kg N/ha, in three split applications. The N supplied by the DCD was accounted for in the 200 kg N/ha application. Additionally, AN and urea fertiliser was also applied in five equal splits in mid-March, late-March, mid-April, late-April and 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.
