Research Topics

Soils are the major terrestrial reservoir of organic carbon, which contributes to many aspects of soil and environmental quality. Heterogeneity and dynamics of soil organic matter (SOM) in space and time require to consider the relevance to functions in soil and in the global C cycle (supply for plant nutrients, improvement of the water-holding capacity, soil aggregation, and sink/source for trace gases) and demands the differentiation into functional pools represented by specific fractions isolated by various approaches. The soil microbial biomass is considered to be one major part of the active or labile SOM pool. The transformation of SOM through microbial decomposition is responsible both for carbon release to the atmosphere and carbon sequestration in soils. Thus, the status of SOC pools particularly in agricultural soils is of special importance to characterize soil C pools and their dynamics under changing environmental factors such as soil management and climate.
