Title: Urine application dates: AC0213, Devon, 2012
Related Party - Organisation (Author): Rothamsted Research - North Wyke
Related Party - Organisation (Funder): Defra
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 is of urine application rates (i.e. total nitrogen applied) and dates applied. The N applied in the nitrification inhibitors was not accounted for in the total N application rate. NA = not applicable. Pyrazole derivative = an additive containing two pyrazole derivatives (1H-1,2,4-triazole and 3-methylpyrazole). If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
