Stable isotopic evidence for the excess leaching of unprocessed atmospheric nitrate from forested catchments under high nitrogen saturation

Abstract µ M, implying that these forested catchments were under nitrogen saturation. To verify that these forested catchments were under the nitrogen saturation, we determined the export flux of unprocessed atmospheric nitrate relative to the entire deposition flux (M atm/D atm M atm/D atm Δ 17 µ M. While showing the average nitrate concentrations of 109.5, 90.9, and 7.3 µ M in FK1, FK2, and MY, respectively, the catchments showed average Δ 17 + + + 3 - atm ]) was estimated to be 10.8, 5.1, and 0.2 µ M in FK1, FK2, and MY, respectively, and the M atm/D atm M atm/D atm 3 - atm leaching from the catchments. While the stream nitrate concentration ([NO3 - M atm/D atm M atm/D atm ratio can be used as a robust index for evaluating nitrogen saturation in forested catchments.
