N2O emissions from winter wheat in 2009, from 3 replicate chamber measurements of the 50% irrigation treatment.The soil–atmosphere exchange of N2O was measured with a mobile fully automated measuring system. Sampling chambers (50cm x 50cm x 15cm) were fixed on stainless steel frames. The lids of the chambers were opened and closed automatically with pneumatic devices. During the closing period air samples from each chamber were taken alternately and injected towards the analytical devices. Soil-atmosphere exchange measurements were made at 3 subplots for each treatment within the split-plot design. Changes in N2O concentration after chamber closure were measured with a gas chromatograph (Texas Instruments SRI 8610C, Torrance/USA) equipped with a 63Ni electron capture detector (ECD) for N2O analysis
