Short summary
We measured the abundance of a nitrogen (N) isotope (15N) in two subtropical forests in China to study the cycling of input N (deposition and addition). Plant leaves in both forests were 15N-depleted relative to the atmospheric standard, likely as an imprint from 15N-depleted deposition. Plant 15N changed into 15N of the added N, indicating incorporation of N into plants. Thus, interpretations of ecosystem 15N from high-N-deposition regions need to include data on the 15N deposition signature.
