Natural 15N abundance of ammonium and nitrate in soil profiles: New insights into forest ecosystem nitrogen saturation

open access: yesEcosphere, 2022
Assessment of nitrogen (N) saturation of forests is critical to the evaluation of the manner in which ecosystems will respond to current and future global changes such as N deposition. However, quantifying N saturation remains a challenge. We developed a
