Abstract:
Cattle slurry was applied to a free draining arable soil, on a commercial farm located in Cheshire, north-west England. Slurry was applied to minimise ammonia emissions using commercial trailing hose machinery to replicated (x3) plots (24 x 24 m) arranged in a randomised block design. The slurry application rate was appropriate for the application technique (i.e. c.65 m3 ha-1) and was based on slurry N analysis. The amount of total slurry N applied was 113 kg ha-1. Nitrous oxide was measured following slurry application in autumn and from an untreated control. Direct N2O measurements were made using 5 static chambers (0.8 m2 total surface area) per plot and analysed using gas chromatography. Measurements continued for about 12 months after slurry application. This dataset is of daily nitrous oxide flux (g N2O-N/ha/d) measurements. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
