Institute for Plant Ecology

We investigate the effects of different abiotic environmental factors (e.g., raised CO2, ozone, salt stress) on plant communities starting at the plant leave and the site to ecosystems level (professorship for experimental plant ecology) and ending in global cycles of C and N (professorship for geoecology and modelling). The applied methods range from biochemical, ecophysiological and microbiological lab investigations about field investigations (e.g., vegetation surveys, measurement of trace gas fluxes at site and ecosystem level) up to process oriented modelling and global models.

DASIM

DASIM - Denitrification in Agricultural Soils: Integrated control and Modelling at various scales

Funding Agency: DFG //  Duration: 2016 - 2023 // PI: Christoph Müller

 

Denitrification is the process of nitrate reduction which allows microbes to breathe under aerobic conditions, is a key process of reactive nitrogen from the soil as inert N2 returns to the atmosphere. The individual steps (NO3- -> NO2- -> NO -> N2O -> N2) are enzymatically controlled by a large number of pro- and eukaryotes. Active denitrifiers communities in soil exhibit distinct regulatory phenotypes (DRP), with characteristic control of individual reaction steps and end products. It is unclear whether DRPs are taxonomically fixed in denitrifiers and how much environmental conditions can change them. Although research on DRPs has been going on for over 100 years, denitrification rates and the emission of gaseous products still cannot be satisfactorily explained and predicted. While the influence of individual environmental conditions is already well understood, the complexity of the overall process with its complicated cellular regulation as a reaction to very variable factors in the soil matrix has not yet been clarified. Key parameters are the oxygen partial pressure in the soil, the content of organic material and its quality, the pH value and the composition of the microbial community, which in turn is determined by soil structure, soil chemistry and soil-plant interaction. In this project we aim to make quantitative predictions of denitrification rates as a function of soil microstructure, organic mass quality, DRPs and atmospheric boundary layer condition. We rely on the latest experimental and analytical methods (X-ray µCT, 15N tracing, NanoSIMS, microsensors, advanced flux detection, NMR spectroscopy, molecular methods including "next generation sequencing of functional gene transcripts") to achieve a very accurate spatial and temporal resolution of the process steps. Improved numerical methods and computer capacities will allow to integrate the results of the individual groups and to develop new denitrification models ranging from the microscale (phase 1) to the field scale (phase 2).

Research Station

Environmental Monitoring and Climate Change Impact Research Station Linden

 

Funding Agency: Hessian State Agency for Nature Conservation, Environment and Geology (HLNUG) // Duration: 2017 - 2029 // PI: Prof. Christoph Müller, PhD

 

A strategic partnership exists between the Hessian State Agency for Nature Conservation, Environment and Geology (HLNUG) and the Justus Liebig University of Giessen, which is documented by the signing of a framework agreement. In addition, the HLNUG was an important associated partner in the LOEWE funding for the FACE2FACE project. The HLNUG significantly supports the implementation of the scientific results of the climate impact research carried out at the Environmental Monitoring and Climate Impact Research Station Linden (UKL) since 1998. A further 3-year grant is intended to continue the work that has been carried out together since 1998. In addition to the continuation of long-term observations (phenology, permanent observation plots) and experiments (Giessen FACE, Biochar), the factors increased CO2 concentrations and increased air temperature will be considered within the framework of the newly constructed Giessen T-FACE facility. The surveys include the continuation of existing data series as well as the inclusion of new integrative analyses, which above all form the basis for the application for further collaborative research projects.

Green Dairy

Funding Agency : LOEWE / Duration: 2022 - 2025 // PI: Dr. Gerald Moser

 

The industrialization of agriculture offers several fundamental problems. Decoupled material cycles with high nitrogen surpluses, greenhouse gas emissions, soil degradation and problems regarding animal welfare result. The "GreenDairy" project aims to optimize agricultural structures and to enable ecologically and economically sustainable farming. By the use of integrated animal-plant agricultural ecosystems gaps of decoupled material cycles are expected to be closed. Additionally, effects of different farming systems (low-input vs. high-input) are to be investigated.

The project draws on the research infrastructure of the organically managed Gladbacherhof, where a digitalized dairy farming system has been established. The digital animal recording, grazing control, feeding and milking robotics, which is enabled by this system, helps to compare low-input systems (mainly roughage) with high-input systems (high proportion of corn silage and concentrated feed). In addition, the project incorporates research in animal, plant, soil, and environmental sciences, as well as agricultural and food economics, to provide a comprehensive picture of the impacts of different systems.

The Institute of Plant Ecology participates in the project area "Environment" with the investigation of greenhouse gas emissions in arable and grassland areas. At this, the climate-relevant gases CO2, CH4 and N2O are recorded using soil air probes and static chambers and are quantified subsequently. The measurements will be carried out over three years so that each crop in the project's crop rotation and the respective previous crops can be taken into account. Both cropland and grassland are analyzed, comparing high- and low-input areas. Thus, the aim is to minimize the emission of climate-relevant gases by an optimized agricultural system.

BioNET

Multi-stage assessment of biobased negative emission technologies (BioNET)

Funding Agency : DLR // Duration: 2022 - 2024 // PI: Prof. Christoph Mueller, PhD


Negative emission technologies that use biomass and biogenic CO2 (biobased NETs) play a central role in net-zero policy strategies. Embedded in agricultural and forestry supply chains, biobased NETs offer numerous options, but they also compete with biomass material and energy use and therefore face large uncertainties about the feasibility of their deployment. However, the deployment of bio-based NETs in Germany has not yet been evaluated in a coherent and integrated manner, especially from the perspective of local and regional deployment.
The aim of the BioNET (Multi-level assessment of biomass-based NETs) project is to create a comprehensive knowledge base for and assess biobased NETs in Germany by combining novel social science research with state-of-the-art biomass competition modeling and trade-off analysis to support local and national decision makers: (1) we compile transparent and accessible information and data on biobased NET concepts tailored to the information needs of different stakeholders, such as energy utilities or public authorities, (2) we develop novel participatory approaches to explore societal and institutional feasibility, (3) we elaborate and evaluate national biobased NET scenarios, including techno-economic modeling and an assessment of trade-offs with respect to the different Sustainable Development Goals.
As a result, the project identifies the window of opportunity for biobased NETs in Germany and enables decision makers from local to national level as well as researchers to include and prioritize the implementation of biobased NETs in their scenarios and strategies, using appropriate dissemination formats (open data, guidelines, policy briefs, etc.).

FACE2FACE

Funding Agency: LOEWE-HMWK // Duration: 2014 - 2017 // Speaker: Prof. Christoph Müller, PhD

What are the consequences of climate change for Central European agriculture?

It is getting warmer - also in Hesse. What does climate change mean for Central European agriculture? In order to investigate the complex effects of carbon dioxide on plants, soils, microorganisms and insects, LOEWE's focus "FACE2FACE" combines two large open-air experimental facilities to form a research platform: the "Free Air Carbon Dioxide Enrichment" systems - FACE for short - at Justus Liebig University in Giessen and Geisenheim University of Applied Sciences. The FACE systems make it possible to regulate the carbon dioxide concentration on defined surfaces and thus simulate the expected state in the middle of the century. Based on their findings, the scientists hope to develop strategies for adapting to climate change and reducing its consequences. They will concentrate on the agricultural ecosystems of grassland, viticulture and vegetable growing, horticulture and fruit growing.
