The two prototypes will be applied in the agricultural Tuscan framework. After the identification of the main cropping systems in Tuscany and their effects of N2O emissions, a series of field trials will be set up in the Interdipartimental Centre for Agro-Ecological Research E. Avanzi (CIRAA), located on the northern coast of Tuscany, near Pisa, and the Cesa Research Centre for Agricultural Technologies and Extension Services in the Province of Arezzo - Ex. Arsia (CATES). They are representative of different pedological and climatic characteristics as well as crop management. A monitoring period of two years will be carried out on these field trials using both prototypes, in order to obtain a comprehensive set of N2O flux data and ancillary parameters.
