Manure Management Network – Webinar Measuring gas emission from livestock farming with chamber and tracer measuring techniques
Gaseous emissions from agriculture contribute significantly to greenhouse gas (GHG) and ammonia in the atmosphere, and climate change and pollution of aquatic ecosystems. Reliable data from measurements and studies is needed for the development of technology and management practice to reduce emissions, calculate emission inventories (e.g. IPCC) and provide valid data to assess emissions reduction for carbon credit trade. Three researchers with extensive experience in measuring gas emission from farming will present the great potential in the use of the chamber and tracer gas measuring method, and pitfalls, understanding, and application of the use of it.
Biography of presenters
Johanna Pedersen Department of Biological and Chemical Engineering, Environmental Engineering Group, Aarhus University
Johanna Pedersen is specialized in high-time resolution measurements of ammonia and non-methane volatile organic compounds (NMVOC) emissions after field application of liquid animal manure (slurry). During her research she has focused on the slurry-soil interactions and the balance between simulating conditions as close to real practice as possible, while obtaining replicate data of high precision and low variation. She has investigated different reduction technologies, including solid-liquid separation, acidification, and low-emission application techniques.
Søren O, Petersen. Department of Agroecology, Aarhus University
Søren O. Petersen has a background in microbial ecology. His research focuses on the interactions between soil, organic amendments and microbial communities, with an emphasis on carbon and nitrogen cycling and the mitigation of greenhouse gas emissions in agricultural systems. He has contributed to fundamental and applied studies on gaseous emissions (such as nitrous oxide and methane), manure management, and environmental controls affecting soil microorganisms.
David Janke; Department Sensors and Modeling, Leibniz-Institut für Agrartechnik und Bioökonomie (ATB), Potsdam, Germany
David Janke is specialized in measuring emissions (mainly methane and ammonia), from livestock housing systems. He focusses on the coupling of different methodological approaches in order to develop highly-scalable, low-cost measurement routines. He coordinates emission research at several experimental farms in Germany and is involved in several national and European joint projects that investigate the measurement, modeling, and mitigation of GHG emissions (e.g. EmiMin, EmiMod, DairyMix, RES4LIVE, or EcoNutri).
Sven G. Sommer Department of Biological and Chemical Engineering, Aarhus University
Sven G. Sommer is a specialist in bio-waste engineering with focus on emission of ammonia (NH3), the greenhouse gases methane (CH4) and nitrous oxide (N2O), separation of animal manure and organic biowaste and biogas production. His research has a strong focus on bio-waste chemistry and biological and chemical processes affecting transformation of organic matter in biowaste. He has been involved in Public Sector Consultancy for most of his career giving advises in environmentally friendly management of animal manure and how to enhance this with incentives and regulations.
