This webinar is aimed at researchers, students and the general public interested in the mitigation of nitrous oxide emissions from synthetic fertilisers in different agricultural agroecosystems. We will cover technologies and practices aimed at reducing emissions while maintaining productivity.

Speakers

Dominika Krol

Dominika Krol is a Senior Research Officer at the Teagasc Crops, Environment and Land-Use programme based in Johnstown Castle. Dominika leads a research programme focused on agricultural gaseous emissions. Her research interest includes impact of management of organic manures and synthetic fertilisers on emissions of nitrous oxide and ammonia in grassland systems. She is contributing to quantification and mitigation of these emissions and refinement of national emission inventories. She currently co-leads several national and international projects, including the NZ-Ireland REEFIR project which focuses on developing higher tier fertiliser emission factors for temperate grasslands. Dominika is a Lead for the Nitrogen Research Pillar in the Teagasc Climate Centre.

Tony van der Weerden

Tony van der Weerden is a principal scientist at the New Zealand Bioeconomy Science Institute. His research area includes greenhouse gas emissions (nitrous oxide, ammonia and methane) from soils and manure management, at the farm- and national inventory scale. He also explores potential mitigation technologies that can be adopted for low-emission farm systems. He currently co-leads several national and international projects, including the NZ-Ireland REEFIR project which focuses on developing higher tier fertiliser emission factors for temperate grasslands. Tony is also a co-lead of the GRA N fertiliser Flagship.

Mart Ros

He has a background in soil science and a PhD from Wageningen University on the availability of phosphorus in managed grasslands. Currently working as a researcher on soil nutrient management in the Sustainable Soil Management team of Wageningen Environmental Research. Together with my colleagues I work on projects that study the relation between agricultural management, nutrient cycling, and environmental losses, with a specific focus on nitrous oxide. The work we do often has a strong connection to policy and serves to support environmental and manure legislation as well as the national emission inventory.

Francisco Salazar

Dr. Francisco Salazar holds a degree in Agricultural Engineering from Universidad de La Frontera, Chile and a Ph.D. from the University of Reading, England. He is a researcher at the Agricultural Research Institute, Remehue Research Center. He has been involved in various national and international research projects, focusing on dairy manure management, organic waste, nutrient losses, greenhouse gases, ammonia volatilisation and carbon and water footprints of agricultural systems. He is a member of international networks on greenhouse gases and livestock production, such as the Global Research Alliance, RAMIRAN, and ManureSouth. He also is part of Chile’s technical team for estimating emissions from the agriculture sector.
