LIFE+IPNOA mobile prototype for the monitoring of soil N2O emissions from arable crops: first-year results on durum wheat [link]Paper  doi  abstract   bibtex   
Agricultural activities are co-responsible for the emission of the most important greenhouse gases: carbon dioxide (CO\textlesssub\textgreater2\textless/sub\textgreater), methane (CH\textlesssub\textgreater4\textless/sub\textgreater) and nitrous oxide (N\textlesssub\textgreater2\textless/sub\textgreaterO). Development of methodologies to improve monitoring techniques for N\textlesssub\textgreater2\textless/sub\textgreaterO are still needful. The LIFE+IPNOA project aims to improve the emissions monitoring of nitrous oxide from agricultural soils and to identify the agricultural practices that can limit N\textlesssub\textgreater2\textless/sub\textgreaterO production. In order to achieve this objective, both a mobile and a stationary instrument were developed and validated. Several experimental field trials were set up in two different sites investigating the most representative crops of Tuscany (Central Italy), namely durum wheat, maize, sunflower, tomato and faba bean. The field trials were realized in order to test the effect on N\textlesssub\textgreater2\textless/sub\textgreaterO emissions of key factors: tillage intensity, nitrogen fertiliser rate and irrigation. The field trial on durum wheat was set up in 2013 to test the effect of tillage intensity (minimum and conventional tillage) and nitrogen fertilisation rate (0, 110, 170 kg N ha\textlesssup\textgreater-1\textless/sup\textgreater) on soil N\textlesssub\textgreater2\textless/sub\textgreaterO flux. Monitoring was carried out using the IPNOA mobile prototype. Preliminary results on N\textlesssub\textgreater2\textless/sub\textgreaterO emissions for the durum wheat growing season showed that mean daily N\textlesssub\textgreater2\textless/sub\textgreaterO fluxes ranged from –0.13 to 6.43 mg m\textlesssup\textgreater-2\textless/sup\textgreater day\textlesssup\textgreater-1\textless/sup\textgreater and cumulative N\textlesssub\textgreater2\textless/sub\textgreaterO-N emissions over the period ranged from 827 to 2340 g N\textlesssub\textgreater2\textless/sub\textgreaterO-N ha\textlesssup\textgreater-1\textless/sup\textgreater. Tillage did not affect N\textlesssub\textgreater2\textless/sub\textgreaterO flux while increasing nitrogen fertilisation rate resulted to significantly increase N2O emissions. The IPNOA mobile prototype performed well during this first year of monitoring, allowing to catch both very low fluxes and peaks on N\textlesssub\textgreater2\textless/sub\textgreaterO emissions after nitrogen supply, showing a good suitability to the field conditions.
