Innovative approaches to reduce ammonia emissions
Ammonia emissions not only mean financial losses for agriculture. They also stress the environment. In this project, we are assessing the efficacy of innovative measures in reducing these emissions. To this end, we are using literature studies and interviews with experts in order to review the existing knowledge. When an assessment is not possible by these means, we conduct investigations on a pilot scale or under practical conditions in the field.
Ammonia emissions inventory
The consequences of ammonia (NH3) emissions are heavy nitrogen losses for Swiss agriculture and negative impacts on the environment. We are modelling NH3 emissions on the basis of periodically conducted, representative surveys of agricultural production techniques and the Agrammon model. In addition, we estimate the future trend of NH3 emissions und model the impacts of emissions-reducing measures.
In the scope of the EU research project ‘EVEMBI – Evaluation and reduction of methane emissions from different European biogas plant concepts’, we are responsible for the methane measurements in Switzerland. We model the methane emissions of biogas plants by means of telemetry and backward Lagrangian stochastic (bLS). For this purpose, we measure methane (for several weeks in every season) in three conceptually different biogas plants.
