Comments Reactive nitrogen (Nr) products are reduced or oxidized nitrogen compounds NH3, NOx, NOy, etc. From 1860 to 1995, energy and food production increased steadily on both an absolute and per capita basis Nr creation also increased from ~15 Tg N in 1860 to 156 Tg N in 1995. The change was enormous, and it increased further from 156 TgN/yr in 1995 to 187 TgN/yr in 2005, in large part because cereal production increased from 1897 to 2270 million tons (20%), and meat production increased from 207 to 260 million tons (26%) (primary source).
