Laboratory Department

Varian CP-3800 Gas Chromatograph with FID, ECD and QUMA QHSS-111 autosampler for the determination of CO2, CH4 and N2O from chamber measurements

The laboratory department of AK is responsible for all analyses coming up from the different groups of the Institute. It consists of a centralized laboratory and a laboratory for stable isotope analysis.

In the centralized laboratory, wet chemical analyses are carried out as well as several instrument based analyses of atmospheric, water, soil and plant samples. 

The stable isotope laboratory focuses on C-, N-, O-, S isotope analysis in gaseous samples as well as in soil and plant samples.

Greenhouse gas emissions

The factors that determine the exchange of trace gases between agricultural production systems and the atmosphere are investigated in order to increase our understanding of the underlying processes and to develop and evaluate mitigation measures.

Impacts of climate change

We examine the impacts of a changing climate on nutrient cycling in agricultural production systems with the aim of understanding and predicting soil chemical processes under changing climatic conditions, allowing the development and adaptation of climate mitigation measures.

Adaptation of production areas and systems

Potential greenhouse gas emissions reductions are quantified for various mitigation measures. New agricultural production systems that are better adapted to a changing climate are developed and evaluated.

 

Soil horizon

Soil science

Agricultural soils can be both sources and sinks of greenhouse gases. The underlying processes are investigated in order to enable an evaluation of the possible contribution of agricultural soils to climate mitigation.

National Emission Inventory Report (NIR)

Every year, the national report for the sectors agriculture and land use is prepared as part of the German National Emission Inventory Report (NIR). All calculations are documented and further developed based on the latest science.
