Impacts of hemiparasitic plants on the vegetation and biogeochemical cycling in two contrasting semi-natural grassland types
… litter mixture were incubated. Using 15N labeling of the ammonium and nitrate pools coupled to a numerical tracing model, we quantified gross N transformation rates. Rhinanthus and Pedicularis litter additions increased N cycling relative to non-parasitic litter additions. In contrast …

Nitrous Oxide Production in Agricultural Soil – Linking Biogeochemical Pathways and Drivers
… trial field sites in the laboratory and used 15N-enriched tracers in two main approaches: partitioning of the sources of N2O production and quantification of the gross rates of microbial processes competing for ammonium (NH4+) and nitrate (NO3-). The varying relative contribution of NH4+, NO3- …
