Biography
Dr Johannes Friedl is a soil scientist at the Institute of Soil Research at the University of Natural Resources and Life Sciences, Vienna. His research in the field of environmental and agricultural science links basic process understanding to applied research questions enabling high impact research and real-world outcomes for sustainable management practice adapted to global climate change in both agricultural and natural environments. He is leading development and application of state-of-the-art monitoring methods to trace nutrient cycling and losses in the soil-plant atmosphere system. He has worked across different agricultural industries as well as within international research collaborations, developing strategies to mitigate environmentally harmful nutrient losses while maintaining pasture and crop productivity. He is currently leading the project NITROUSSOURCE as an ESPRIT fellow funded by the Austrian Science Fund (FWF), investigating nitrous oxide production and consumption in agricultural soils.Research Interest
- Nitrogen/ Carbon turnover in the soil, plant atmosphere system
- Biogeochemistry of plant-soil-microbe interactions in agro-ecosystems
- Biosphere-atmosphere exchange of environmentally important greenhouse gases
- Balance and magnitude of reactive and non-reactive nitrogen losses from soils
- Stable Isotopes in Environmental Sciences
