The experiments will be conducted in outdoor lysimeters based at the Unitá di Ricera per la Risicoltura (CREA-RIS) in Northern Italy, during the growing season (May – September) of 2016. The objective is the study the effect of alternate wetting and drying (AWD) on CO2 flux partitioning across soil, root and rice plant respiration. Besides, an experiment of 15N Labeling will be carried out aiming at the study of the effects of AWD on total denitrification and the respective contributions of nitrification and denitrification to N2O emissions.
