GHG mitigation trough model based optimisaiton and evaluation of cropping systems for renewable ressources. (THG-Emissionsminderung)
Project
Project code: 22402917
Contract period: 01.01.2019
- 31.12.2021
Budget: 252,907 Euro
Purpose of research: Experimental development
Keywords: greenhouse gas emissions, nitrous oxide emissions, nitrate leaching, renewable ressources
The overall objective of the project outlined is to contribute to the reduction of greenhouse gas (GHG) emissions in agricultural production systems for renewable ressources. There is a particular need for research and optimization in terms of methods for assessing the climate effects of cropping systems, taking into account their interactions with regional soil and climatic conditions. The focus of this project is on the three relevant components of GHG assessment: yield (potential GHG savings), direct N2O emissions and nitrate leaching as the basis for indirect N2O emissions. The equally important aspects of the soil carbon balance as well as ammonia and methane emissions are not to be addressed within this project. The contribution of this project to climate protection consists in an improved selection and / or design of cultivation methods both for agricultural practice and for the design of promotional programs. Thereby both management effects and their interaction with regional natural conditions will be addressed. The overall project is divided into 9 work packages, which are to be tackled in close cooperation between the project partners Christian-Albrechts-University Kiel and Thünen-Institut Braunschweig. Specifically, the following APs are defined: AP1 - project coordination, AP2 - preparation of experimental data for model calibration and evaluation, AP3 - calibration and evaluation of models for estimating productivity, direct nitrous oxide emissions and nitrate leaching of cropping systems, AP4 calculation of GHG indicators for the data sets of the AP2, AP5 analysis of soil and climatic effects on GHG indicators, AP6 - Comparative assessment of applicability of models, AP7 - Model-based optimization of cropping systems, AP8 - Meta models for forecasting of N leaching in NaWaRo systems and AP9: Stakeholder workshops
