"C-BNF" (cultivation-induced biological nitrogen fixation) represents Nr creation from cultivation of legumes, rice, and sugarcane. "Fossil fuel" represents Nr created from fossil fuel combustion. "Total Nr" represents the sum created by these three processes. Reproduced from Galloway et al. (2003); copyright American Institute of Biological Sciences.
