Abstract The soil nitrogen (N) cycle exhibits a variety of complex biochemical reactions in which N species such as NO2-, NO and N2O are produced and consumed by co-existing processes that respond differently to the local environmental conditions. Key to understanding the soil N cycle in its full complexity is the development and application of methods that allow a quantification of individual pathways and processes that are responsible for the build-up and/or emission of N compounds. Triplet 15N tracer experiments (TTE) have been developed and applied to allow a source-related quantification of N species such as NO2-, and N2O by different biochemical pathways (e.g. ammonia oxidation and nitrate reduction) that are related to multiple N sources (NH4+, NO3- and Norg). An analysis of a TTE requires the application of either a numerical or analytical model. Because of the ease of application it is desirable to use analytical models. However, available analytical solutions suffer from serious drawbacks concerning the quantification of N fluxes related to soil organic N. In this paper we describe the development and application of a new inverse abundance approach (IAA) to analyse a TTE. Theoretical and experimental data sets of soil N2O release were analysed by the new method. The IAA was also applied to an already existing data set to identify fractions of the soil nitrite pool related to NH4+, NO3- and Norg. We show that the IAA provides a reliable and comprehensive data evaluation of a TTE.
