Abstract:
An experiment was conducted at North Wyke, Devon, UK, using 1 ha hydrologically isolated grassland plots on a clay loam soil (38% clay) overlaying an impermeable clay subsoil (the Rowden facility). Half of the plots are drained, with tile drains at 40 m spacing and 85 cm depth, with permeable backfill to within 30 cm of the surface, and with secondary mole drainage at 40 cm depth and 2 m spacing. Cattle slurry was applied at a target rate of 50 m3 ha-1 using a trailing shoe slurry spreader to each of three replicate drained and undrained plots at three times of year: autumn (September 2008), spring (early May 2009) and summer (late June 2009). There were, however, only two replicate plots for the autumn and spring cattle slurry undrained treatments. At each application timing three replicate control plots, receiving no slurry, were also established on both the drained and undrained treatments. Nitrous oxide emissions were measured from each plot following slurry application, using the static chamber method, with 5 replicate chambers located in a sub-plot (18 x 6 m) at the centre of each 1 ha plot. Emission measurements were made on up to 40 occasions over a 12 month period following each slurry application. This dataset is of daily nitrous oxide flux (g N2O-N/ha/d) measurements. 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.
