Determine the maximum N2O emissions-reduction that can be achieved with a dual-inhibitor N-fertilizer as compared to urea. Determine maximum N-rate reduction possible with dual-inhibitor N-fertilizer that maintains optimal yields of canola and wheat. Determine the agri-environmental optimum N rate for urea and a dual inhibitor N fertilizer as an N source for canola.
