dc.description.abstractNitrous oxide emissions from a network of agricultural experiments in Europe and Zimbabwe ere used to explore the relative importance of site and management controls f emissions. At each site, a selection of management interventions were compared within replicated experimental designs in plot based experiments. Arable experiments ere conducted at Beano in Italy, El Encin in Spain, Foulum in Denmark, Log°arden n Sweden, Maulde in Belgium, Paulinenaue in Germany, Harare in Zimbabwe and ulloch in the UK. Grassland experiments were conducted at Crichton, Nafferton and eaknaze in the UK, G.od. oll .o in Hungary, Rzecin in Poland, Zarnekow in Germany and 0 Theix in France. Nitrous oxide emissions were measured at each site over a period of t least two years using static chambers. Emissions varied widely between sites and s a result of manipulation treatments. Average site emissions (throughout the study eriod) varied between 0.04 and 21.21 kg N2O-N ha−1 yr−1, with the largest fluxes and ariability associated with the grassland sites. Total nitrogen addition was found to be 5 the single most important determinant of emissions, accounting for 15% of the variance using linear regression) in the data from the arable sites (p < 0.0001), and 77% n the grassland sites. The annual emissions from arable sites were significantly greater han those that would be predicted by IPCC default emission factors. Variability in N2O ithin sites that occurred as a result of manipulation treatments was greater than that 0 resulting from site to site and year to year variation, highlighting the importance of anagement interventions in contributing to greenhouse gas mitigation.uk
