Abstract:
At Newcastle University’s Cockle Park Farm near Morpeth, north-east England (clay loam topsoil texture), direct nitrous oxide (N2O) and ammonia (NH3) emissions were measured from replicated (x3) plots (24 x 13 m), following spring applications of manufactured nitrogen (N) fertilisers to winter barley. A control treatment was included where no N fertiliser was applied. Ammonium nitrate (AN) fertiliser (34.5% N) or urea fertiliser (46% N) were applied at a rate of 160 kg N/ha, in three split applications (mid-March, late-March and early-April). In separate treatments, a commercially available nitrification inhibitor was 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. The N supplied by the DCD was accounted for in the 160 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 is of soil mineral nitrogen (SMN) values measured to 0-90 cm depth before experimental treatments were applied.
