Abstract:
An experiment was carried out at the AFBI Hillsborough research farm near Hillsborough, south-east Northern Ireland (sandy clay loam/clay loam topsoil texture) using small field plots (3 x 8 m) arranged in a randomised block design with three replicates per treatment. Cattle urine (at 5 L/m2), synthetic urine (at 5 L/m2) and cattle dung (at 20 kg/m2) was applied to grassland in early-April (spring), late-June (summer) and in mid-September (autumn) 2012. The synthetic urine was prepared using the formulation described for “R2” in the paper by Kool et al., (2006). A control treatment was included where no urine or dung was applied. In a separate treatment, a commercially available nitrification inhibitor was tested; dicyandiamide (DCD) was pre-mixed with the urine prior to application to give an application rate of 10 kg /ha for the DCD. The urine and dung was collected from lactating dairy cows at the AFBI Hillsborough research farm, kept refrigerated at <4°C and applied within seven days of collection.

What artificial urine composition is adequate for simulating soil N2O fluxes and mineral N dynamics Soil Biology and Biochemistry 38, 1757-1763. This dataset is of dung and urine application rates (i.e. total nitrogen applied) and dates applied. The N supplied by the DCD was not accounted for in the total N application rate. 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.
