Abstract:
At a grassland site near Rothamsted Research, North Wyke in south-west England (sandy clay loam topsoil texture) small field plots (10 x 3 m) were arranged in a randomised block design with three replicates per treatment. Cattle urine (at 5 L m-2) was applied to grassland in mid-March and in early September 2012. A control treatment was included where no urine was applied. In separate treatments, two commercially available nitrification inhibitors were tested; dicyandiamide (DCD) and an additive containing two pyrazole derivatives (1H-1,2,4-triazole and 3-methylpyrazole) were pre-mixed with the urine prior to application to give application rates of 15 kg/ha and 5 L/ha for the DCD and the pyrazole derivatives, respectively. The urine was collected from lactating dairy cows at Reading University, kept refrigerated at less than 4°C and applied within two 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. Water-filled pore space values are the mean of 3 blocks with measurements taken across each block. 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.
