Full descriptionThe Automated Greenhouse Gas Sampling system measured the soilatmosphere exchange of N2O 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.
