Question: Historical nitrogen fertilizer use in agricultural ecosystems of the contiguous United States during 1850–2015: application rate, timing, and fertilizer types
Answer: A tremendous amount of anthropogenic nitrogen (N) fertilizer has been applied to agricultural lands
to promote crop production in the US since the 1850s. However, inappropriate N management practices have
caused numerous ecological and environmental problems which are difficult to quantify due to the paucity of
spatially explicit time-series fertilizer use maps. Understanding and assessing N fertilizer management history
could provide important implications for enhancing N use efficiency and reducing N loss.
