LIFE+ IPNOA Project (LIFE11 ENV/IT/000302) is developed within the program Life + Environment Policy and Governance project application - Call 2011.
This project intends to develop a different approach through the on-site determination of N2O fluxes by means of accumulation chambers equipped with continuous N2O analyzers. To this purpose, two different prototypes will be developed, one portable, the other to be used in a fixed site (station prototype). Upon their design, realization, laboratory calibration, and field validation, we expect to be able to measure N2O fluxes directly in the field, in a very short lapse of time, and with better sensitivity compared to other approaches. These aspects are very important to evaluate annual budgets for integrated areas, considering the large spatial and temporal variabilities of N2O emissions.
Through a series of carefully planned field trials in two different sites of the Tuscany Region, characterized by distinct pedological and climatic conditions as well as different crop management, we expect to be able to obtain a sufficiently reliable figure for the whole N2O emission from Tuscan arable lands.
The main objectives of this project are:
1. The development of two prototypes for monitoring N2O fluxes, one fixed and the other portable, to measure N2O emissions from soils in order to improve the present monitoring on this greenhouse gas output;
2. The identification of the best agro-ecosystem management practices to reduce these emissions from agriculture in the Tuscany Region;
3. Scenario analysis at regional scale to identify the measures to be adopted as financial incentives for N2O mitigation from agricultural practices.
