New evidence, obtained using a robust method for measuring the δ 15 N of NO 3 − ‐N in soil, is consistent with denitrification being the major determinant in the vertical distribution of NO 3 − ‐δ 15 N in soil profiles. These data also suggest that varying moisture regimes result in different effects of soil NO 3 − ‐N leaching on residual whole soil δ 15 N. Copyright © 2001 John Wiley & Sons, Ltd.
