The cumulative Nr emissions are 17.4 Pg N (8.6 Pg NH3-N and 8.8 Pg NOx-N, respectively) for 8000 BC through the year 2000, with 28% of this amount emitted during 1850–2000, 42% during 1–1850, and 30% during the previous 8,000 years. Forest and savannah burning represent the major cumulative flux of both NH3-N and NOx-N (3.5 and 5.8 Pg, respectively). Livestock production and biofuel burning are responsible for emissions of 3.3 and 1.2 Pg NH3-N, respectively, while the application of synthetic fertilizers contributes 0.26 Pg NH3-N. The cumulative NOx-N emission was higher from biofuel than fossil fuel use (1.9 vs. 1.1 Pg). The majority of the total cumulative anthropogenic Nr emission over the last 10,000 years occurred in the pre-industrial period and could have increased soil N pools of some remote ecosystems much earlier than is currently assumed.
