Abstract:
On a commercial farm near Pencaitland, Eastern Scotland (sandy clay loam topsoil texture), direct N2O-N emissions were measured from replicated (x3) plots (3 x 10 m) following spring applications of manufactured nitrogen (N) fertilisers to spring barley. A control treatment was included where no N fertiliser was applied. Ammonium nitrate (AN) fertiliser (34.5% N) was applied at 5 different rates; 40, 80, 120, 160 and 200 kg N/ha, and urea fertiliser (46% N) at a rate of 120 kg N/ha, in two split applications (early-April and late-April). 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 120 kg N/ha, which was applied in two splits. Additionally, AN fertiliser was also applied in three equal splits of 40 kg N/ha in early-April, late-April and early-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. The measurements were taken across all treatments in each block. NA = not applicable. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
