During corn production, the team found that cumulative N2O emissions were 53% lower with SuperU when compared with granular urea, and crop yields were unaffected. But when SuperU was used the following year with barley, cumulative N2O emissions were the same as those from granular urea. Furthermore, there was no lingering effect of SuperU on emissions when alfalfa was the subsequent crop. Overall, N2O–N emission losses as a percentage of total N applied were very low at ≤0.21%.
