Assessment of nitrogen (N) saturation of forests is critical to evaluate how ecosystems will respond to current and future global changes such as N deposition. However, quantifying N saturation remains a challenge. We developed a conceptual model of N saturation stages in forest ecosystems based on i) a hypothetical relative rate of ammonification, nitrification, and denitrification, ii) concentrations of ammonium and nitrate in the soil, and iii) 15N enrichment pattern of bulk soil N, ammonium,...
