Carbon, Water and Energy Fluxes of Terrestrial Ecosystems in Italy - The Greenhouse Gas Balance of Italy - page 31

Fig. 2.3 Comparison of two cropland sites: IT-BCi cultivated with maize all the years and
IT-Be2 cultivated with alfalfa in 2007-2009 and maize in 2010. The colors are instantaneous
(half hour) CO 2 fluxes in umol CO 2 m − 2 s − 1 . It is possible to note the different magnitude of
the uptake between the two species and the effect of the management practices. The third site
(IT-MBo) is a grassland site and it is interesting to note the low fluxes during winter and the
growing season characterized by two assimilation picks
