Reduced
tillage systems are more profitable in the moderate and high rainfall zones with 2011 crop price and
input cost assumptions but they are less profitable in the drier rainfall zone. Even a more inclusive
accounting with LCA that includes credits for reductions in N2O emissions, fuel usage and fertilizer production
was insufficient to compensate for the lower returns. With the net market price assumption of
2.48 $ CO2e1 ha1 yr1
, the CO2e credits for reducing tillage ranged from 0.27 to 1.63 $ CO2e1 ha1 yr1
across the region.
