This platform allowed the possibility to assess the net effects of alternative
management practices applied spatially to different crops as, for example, the
adoption of a minimum tillage on grain maize (Fig.
10.1
). Under this scenario, the
minimum tillage adoption allowed the accumulation of about 1.1 t ha

of SOC on
average, saving more than 4 Mt of CO

eq considering also the other GHG.
Another attempt to investigate the effect of the change in land use on SOC
stock at very high resolution was made by Coslovich (
2011
). He applied the GEF-
SOC system (Easter et al.
2007
), which links Century model with GIS data, to the
administrative unit of Padova (NE Italy). Reconstructing the past land use since
1800, he was able to track the SOC evolution during the last century, making also
a prediction of the future values according to two climatic scenarios (Had3A1FI
and PCM-B1) (Fig.
10.2
).
