Abstract:
An experiment was carried out near Aberaeron, mid Wales (clay loam topsoil texture) using small field plots (3 x 6 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 mid-April (spring), early-July (summer) and in mid-September (autumn) 2013. 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 Reading University, kept refrigerated at <4°C and applied within seven days of collection.

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. The first measurement is a 'background' measurement i.e. before any treatments were applied. NA = not applicable. ND = not determined. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
