Abstract:
An experiment was carried out at the SRUC Crichton research farm near Dumfries, south-west Scotland (sandy 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 in summer & autumn and c.1.7 L/m2 in spring) and cattle dung (at 20 kg/m2) was applied to permanent grassland in early-April (spring), late-June (summer) and in early-October (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 dairy cows at the SRUC Crichton Dairy Research Center, kept refrigerated at <4°C and applied within seven days of 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. 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.
