Abstract:
An experiment was carried out at Rothamsted Research - North Wyke near Okehampton, south-west England (clay 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-May (spring), early-July (summer) and in late-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 Reading University, kept refrigerated at <4°C and applied in less than 2 days after collection.

This dataset contains daily rainfall (mm), daily maximum air temperature (degree Celsius) and daily minimum air temperature (degree Celsius) measured from either the closest meteorological station to the experimental site or from instruments located at the experimental site. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
