Abstract Intensive fertilization of grasslands with cattle slurry can cause high environmental nitrogen (N) losses in form ammonia (NH 3 ), nitrous oxide (N 2 O), and nitrate (NO − ) leaching. Still, knowledge on short-term fertilizer N partitioning between plants dinitrogen emissions is lacking. Therefore, we applied highly 15 N-enriched (97 kg ha −1 to pre-alpine grassland field mesocosms. We traced the plant-soil system denitrification , O) over 29 days temporal resolution. Gaseous as well O at about 20 were observed only within first after dominated by NH .

Abstract The special issue summarises and highlights key findings of the research unit DASIM funded by German Research Foundation (DFG) on process denitrification. Progress was made in several areas including development new advanced methods to quantify N 2 fluxes such as a 15 gas flux method, enhanced Raman spectroscopy incubation system study plant-soil interactions He-O atmosphere. Understanding denitrification disturbed structured soil gained combining X-ray CT scanning microbial ecology methods. High resolution models developed part were able successfully simulate experimental data provide valuable insights for improvement existing ecosystem models. Improved tracing tools analysis soil-plant systems have been that are extensively used associated partners. brought together an interdisciplinary network researchers interested analytical but also modelling aspects. This includes close collaboration with FAO/IAEA centre Nuclear Techniques Food Agriculture United Nations which resulted open access book describes DASIM. impact scientific community is manifold will most likely lasting understanding nitrogen cycling terrestrial ecosystems.
