Nitrogen (N) deposition has been shown to alleviate N limitations on ecosystem productivity, increasing the terrestrial carbon (C) sink. Accurately quantifying the fate of deposited N is essential for reliably estimating its contribution to the global C sink. The authors conducted an extensive analysis and modeling of 829 observational data points to elucidate the retention patterns of reduced N (NHx) and oxidized N (NOy) deposited in ecosystems and evaluate their contributions to terrestrial C sinks via stoichiometric scaling.
