Collaborative project: Measuring and Modelling Greenhouse- Gas Emissions and nitrate leaching of raw material crop rotations (MASTER)
Project
Project code: 22032018
Contract period: 01.03.2019
- 28.02.2022
Budget: 195,172 Euro
Purpose of research: Experimental development
Keywords: greenhouse gas emissions, crop rotation, humus production, renewable ressources
The project MASTER aims to enhance the current state of knowledge regarding greenhouse gas emissions and soil carbon sequestration from raw material crop cultivation which is the basis for the development of site specific, praxis-oriented mitigation strategies. Within the project master, the subproject "Modelling and measuring greenhouse gas emissions and nitrogen-leaching from raw material crop rotations” will quantify long term greenhouse gas emissions and nitrate leaching using the biogeochemical model DNDC. The model will be used to simulate the addressed fluxes for German soil-climate regions and assess mitigation strategies for these regions. In a first step, the model will be calibrated on high resolution flux measurements from field experiments conducted in the project MASTER. Independent measurements will be used to validate the model. The in this way trained model will be used for extrapolations in space and time. Temporal extrapolations will allow investigating long-term effects of established raw material crop rotations on the interaction of greenhouse gas fluxes, soil carbon sequestration and nitrate leaching for the field experiments. The spatial extrapolation includes the modelling of mitigation scenarios in raw material crop rotations for soil-climate regions in Germany so that the interaction of natural conditions and mitigation strategies can be analysed which is an important improvement compared to TIER 1 approaches. Within the joint research project MASTER the Thünen Institute will analyse gas samples and quantify greenhouse gas fluxes from field experiments.
