Abstract

AbstractWe investigated the δ15N profile of N (extractable NH, NO, and organic N (EON)) in the soil of a N‐saturated subtropical forest. The order of δ15N in the soil was EON > NH > NO. Although the δ15N of EON had been expected to be similar to that of bulk soil N, it was higher than that of bulk soil N by 5‰. The difference in δ15N between bulk soil N and EON (Δ15Nbulk‐EON) was correlated significantly with the soil C/N ratio. This correlation implies that carbon availability, which determines the balance between N assimilation and dissimilation of soil microbes, is responsible for the high δ15N of EON, as in the case of soil microbial biomass δ15N. A thorough δ15N survey of available N (NH, NO, and EON) in the soil profiles from the organic layer to 100 cm depth revealed that the δ15N of the available N forms did not fully overlap with the δ15N of plants. This mismatch in δ15N between that of available N and that of plants reflects apparent isotopic fractionation during N uptake by plants, emphasizing the high N availability in this N‐saturated forest.
