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 measurements of soil moisture as soil water-filled pore space (%) taken on the same days as nitrous oxide emissions measurements were made. Measurements were taken from all treatments. The first measurement is a 'background' measurement i.e. before any treatments were applied. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
