Despite more than 100 years of research into the biochemistry and ecology of microbial N transformations, our understanding of how plants, microbiota and their physical environment shape the N cycle remains fragmentary. At the same time, we are in the midst of a global experiment, augmenting the N cycle to unprecedented levels. Relevant current research addresses, but is not limited to, N transformation processes connecting stable and reactive pools in terrestrial and aquatic ecosystems, the balance between N retaining and dissipating processes, transport and fate of reactive N in the environment and emission and uptake of gaseous N.
This session is open for contributions advancing our understanding of N-transformation processes on all scales, ranging from the micro-site to the watershed. Both field and laboratory studies are welcome. We are particularly interested in contributions reflecting recent methodological advancements in measuring (or inferring) N-transformation rates and their underlying biotic and abiotic components. Studies addressing spatiotemporal variabilities (“hot spots” and “hot moments”) and modeling approaches aiming to overcome variability and scale boarders are highly welcome.
