Land-atmosphere exchange of N2 O, CH4 and CO2 from a Mediterranean rotation cropland

To assess the land atmosphere exchanges linked to agricultural management activities, we conducted two field campaigns over the ICOS-candidate ecosystem site of Borgo Cioffi, a rotation cropland in Southern Italy, measuring fluxes of CH 4 and CO 2 as well as N 2 O, obtaining the temporal evolution of the exchange dynamics for the prevailing GHG. The interested crops were Lolium italicum and Sorghum bicolor, two fodder crops very common in the region. The results showed that the tilled field acted as a source for all GHGs in both cases.
