Fig. 9. Carbon mitigation potential under no-till in the Argentine Pampa Region. Estimations were performed assuming a C sequestration of 460 kg C ha–1 yr–1 under no-till between Years 4 to 9 from installation, a C saving of 31 kg C ha–1 yr–1 due to lower fuel consumption and an increase of 1 kg C soil kg–1 N fertilizer applied, with rates of 20 kg N ha–1 greater for corn and wheat under the wheat/soybean–corn–soybean rotation. An increase of 1 kg N–N2O emitted by denitrification under no-till was also assumed.
