The 15N gas-flux method to determine N2 flux: a comparison of different tracer addition approaches [PDF]
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.

Nitrite isotope characteristics and associated soil N transformations
Nitrite (NO2 −) is a crucial compound in the N soil cycle. As an intermediate of nearly all N transformations, its isotopic signature may provide precious information on the active pathways and processes.

Microbial carbon recycling – an underestimated process controlling soil carbon dynamics – Part 1: A long-term laboratory incubation experiment [PDF]
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]
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.

Diversity of management strategies in Mesoamerican turkeys: archaeological, isotopic and genetic evidence [PDF]
The turkey (Meleagris gallopavo) represents one of the few domestic animals of the New World. While current research points to distinct domestication centres in the Southwest USA and Mesoamerica, several questions regarding the number of progenitor ...
