Abstract:
An experiment was carried out near Stratford-upon-Avon, central England (clay topsoil texture) using small field plots (4.5 x 3.8 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 early-May (spring), mid-August (summer) and in mid-October (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 is of soil mineral nitrogen (SMN) values measured to 0-90 cm depth across all 3 application timing experiments at the start of the study (i.e. spring 2013) & before the spring 2013 experimental treatments were applied.
