Abstract: |
|
Soil N2O fluxes from winter wheat were monitored over one season with an automated measuring and analysis system allowing for a high temporal resolution. Emissions were measured from different irrigation intesities accordding to following experimental set up:
3 different irrigation treatments:
Fully-irrigated (I-50%). The crop will be irrigated when 50% of the plant available water capacity (PAWC) is depleted.
Deficit-irrigated 1 (I-60%). The crop will be irrigated when 60% of the PAWC is depleted.
Deficit-irrigated 3 (I-85%). The crop will be irrigated when 85% of the PAWC is depleted.
N2O emissions were measured with the closed chamber method with 3 replicates per treatmet for the period from June to October 2009 |

Automated closed chamber system |
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.
