Climate change may significantly impact crop yields and soils of managed dryland agriculture.In this study the DNDC model together with climatic outputs from different atmospheric general circulation models (GCMs) were used to investigate the influence of the projected climate change and management practices on soil organic carbon (SOC) dynamics and crop yield under dryland agriculture of Chinese Loess Plateau,identifying the management practices which the greatest potential to mitigate climate change and to increase SOC in this area.
