Collaborative project: Measurement and balancing of material flows in agricultural systems with the purpose of reducing greenhouse gas emissions (MASTER)
Project
Project code: 22032118
Contract period: 01.03.2019
- 28.02.2022
Budget: 249,858 Euro
Purpose of research: Experimental development
Keywords: greenhouse gas emissions, crop rotation, humus production, renewable ressources
The purpose of the project is a fundamental expansion of knowledge about greenhouse gas emission, carbon fixation and carbon dynamic in agricultural crops. The results shall be used as a base to implement practical and location specific reduction strategies to prevent greenhouse gases. Therefor N2O-Emissions will be measured in continuous field experiments with high-definition and the processes of forming greenhouse gases (microbial processes, storage and decomposition of carbon) will be analyzed. The Measurements of N2O-flows will be used to observe the mechanism and influential factors for the N2O emergence. An essential innovation is the analyses of the soils N-dynamic and N2O-flows in dependence with C-decomposition processes. The N2O measurement data also serves for validating models. The long term analyses of humus dynamics and carbon quantities allow the derivation of coefficients of the humus reproduction for energy plants and digested residues. In field trials at the site in Trossin (Bavaria) practically relevant and site specific crops (maize, rape, winter rye, lucerne grass) will be evaluated. Drought resistant sorghum bicolor varieties will be evaluated in comparison with Maize regarding greenhouse gas emissions. Sorghum is for the region with warm and dry soils predestinated and therefore will be evaluated. Organic and mineral fertilizer variants and an intensive intermediate crop will be included in the evaluation. The cultivation systems will be analyzed in regard of their soil processes, yield potential, crop quality as well as environment-, climate- and resource efficiency. Long time effects of crop rotation and fertilizer systems that could not be quantified before will be analyzed. At the foundation of measurement data from own trials and experimental data from past trials material-, energy-, and greenhouse gas balances will be calculated.
