Development of delta(15)N stratification of NO(3)(-) in soil profiles

Rapid Commun Mass Spectrom. 2001;15(15):1274-8. doi: 10.1002/rcm.342.

Abstract

New evidence, obtained using a robust method for measuring the delta(15)N of NO(3)(-)-N in soil, is consistent with denitrification being the major determinant in the vertical distribution of NO(3)(-)-delta(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 delta(15)N.
