The 15N gas-flux method to determine N2 flux: a comparison of different tracer addition approaches [PDF]
SOIL, 2020 The 15N gas-flux method allows for the quantification of N2 flux and tracing soil N transformations. An important requirement for this method is a homogeneous distribution of the 15N tracer added to soil.

Microbial carbon recycling – an underestimated process controlling soil carbon dynamics – Part 1: A long-term laboratory incubation experiment [PDF]
Biogeosciences, 2015 Independent of its chemical structure carbon (C) persists in soil for several decades, controlled by stabilization and recycling. To disentangle the importance of the two factors on the turnover dynamics of soil sugars, an important compound of soil ...

Microbial carbon recycling: an underestimated process controlling soil carbon dynamics – Part 2: A C3-C4 vegetation change field labelling experiment [PDF]
Biogeosciences, 2015 The mean residence times (MRT) of different compound classes of soil organic matter (SOM) do not match their inherent recalcitrance to decomposition. One reason for this is the stabilization within the soil matrix, but recycling, i.e.

Stable isotope analysis of dynamic lipidomics [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2017 Metabolic pathway flux is a fundamental element of biological activity, which can be quantified using a variety of mass spectrometric techniques to monitor incorporation of stable isotope-labelled substrates into metabolic products. This article contrasts developments in electrospray ionisation mass spectrometry (ESI-MS) for the measurement of lipid ...
