Nitrogen applied to the surface of the land for agricultural purposes represents a significant
source of reactive nitrogen (N r) that can be emitted as a gaseous N r species, be denitrified
to atmospheric nitrogen (N 2), run off during rain events or form plant-useable nitrogen in the
soil. To investigate the magnitude, temporal variability and spatial heterogeneity of nitrogen
pathways on a global scale from sources of animal manure and synthetic fertilizer, we
developed a mechanistic parameterization of these pathways within a global terrestrial land …
