“…The results are consistent with the observations of previous research (Mikhailova et al, 2000;Puget and Lal, 2005) in which croplands generally held the lowest SOC and TN amounts in comparison with forests and grasslands. Moreover, the results suggest that the extent of land use made an important impact on the distribution of SOC and TN contents in different land uses in the area, that is, both SOC and TN contents decreased with the increasing intensity of land use and management practices on the whole, which supports the findings of Paustian et al (1997) and Zeidler et al (2002). They found that SOC amount or soil nutrients decreased with increasing soil physical disturbance or land intensification.…”

“…SOC and TN, often tightly coupled, are controlled by a number of natural and anthropogenic factors, including climate, vegetation, topography, parent material, intrinsic soil properties, land use and management practices, etc. (Homann et al, 1995;Paustian et al, 1997). A better understanding of SOC and TN contents and their relationships with these controlling factors is critical to evaluate current regional, continental and global soil C and N pools as well as potentials for C sequestration and N conservation to offset anthropogenic greenhouse gas emissions.…”

“…), v.64, n.1, p.83-99, January/February 2007 The Century Ecosystem Model -Century is a model of soil organic matter and nutrient dynamics that emphasizes the decomposition of soil organic matter and the flux of C and N within and between different components (Parton et al, 1987). The grassland/crop and forest systems have different plant production submodels that are linked to a common soil organic matter and nutrient cycling submodel, which has been fully described before (Metherell et al, 1993;Paustian et al, 1997).…”

“…Obviously, the different conditions and management practices that affect SOC dynamics were not fully represented by the fourteen long-term experiments used in our study. More realistic approaches like the use of dynamic simulation systems linked to geographic information systems (GIS) would allow better assessments of SOC stocks at a regional or national level (Paustian et al, 1997b;Fallon et al, 2002). However, despite the limitations, our study has provided a feasible first estimation for the potential of tillage reduction in agricultural soils of Mediterranean Spain to mitigate GHG emissions.…”
