National Inventory of Reactive Nitrogen

Metadata Updated: November 12, 2020

The effectiveness of management actions in reducing the release of excess nitrogen (N) to the environment is best assessed if N fluxes across air, land and water are regularly quantified at relevant scales. This dataset contains comprehensive 2002, 2007, and 2012 inventories of inputs and non-hydrologic N losses along with fossil fuel emissions, food demand, and terrestrial N surpluses for all HUC-8 subbasins of the contiguous United States using peer-reviewed, publicly available datasets.
