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 bandspreading and surface broadcast application with slurry applied across the whole area of the plot for surface broadcast treatments and applied in bands spaced 20cm apart to simulate bandspread 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 contains measurements of soil moisture as soil water-filled pore space (%) taken on the same days as nitrous oxide emissions measurements were made. Water-filled pore space values are taken from control treatments. In both spring and autumn, the first measurement is a 'background' measurement i.e. before any treatments were applied. 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.
