Abstract:
At the AFBI Hillsborough research farm near Hillsborough, south-east Northern Ireland (clay loam topsoil texture), direct N2O-N emissions were measured from replicated (x3) plots (4 x 12 m) arranged in a randomised block design. Dairy cattle slurry (30 m3/ha) was applied to permanent grassland in autumn (early-October) and spring (early-April). The cattle slurry was applied using watering cans simulating band spreading and surface broadcast application with slurry applied across the whole area of the plot for surface broadcast treatments and slurry was applied in bands spaced 20cm apart to simulate band spread treatments. In two separate treatments, the commercially available nitrification inhibitor - dicyandiamide (DCD) was applied by knapsack sprayer to the sward, within 1 hour of slurry application by surface broadcast and bandspreading, to give a DCD application rate of 10 kg /ha (6.5 kg N/ha). An untreated control treatment was included where no slurry was applied. This dataset is of soil mineral nitrogen (SMN) values measured to 0-90 cm depth before experimental treatments were applied.
