Title: Daily nitrous oxide (N2O) flux measurements: AC0101, Devon, 2007

Abstract:
At Rothamsted Research - North Wyke in south west England nitrous oxide (N2O) emissions were monitored following spring ammonium nitrate fertiliser applications at 6 different rates; 0 (i.e. untreated control), 70, 90, 130, 160 and 200 kg N ha-1. Up to two separate fertiliser applications were made in order to reach the target application rate. There were 3 replicate plots (4 x 12 m) of each treatment arranged in a randomised block design. The plots were established on a winter wheat crop sown the previous autumn, on a coarse sandy loam soil. Direct nitrous oxide emissions were measured from each treatment for 12 months using the static chamber technique (3 chambers per plot) and GC analysis. This dataset is of daily nitrous oxide flux (g N2O-N/ha/d) measurements. The first two measurements are 'background' measurements i.e. before any treatments were applied. If the data file is downloaded/opened in excel, dates may appear as dd-mm-yy instead of the standard yy-mm-dd.
