In order to protect and stimulate microbial activities of soils we must understand the link between the diversity and functioning of microbial communities. To reach this goal we decipher the genetic information of DNA directly extracted from soil and study their variability in response to indigenous soil factors and important environmental parameters.

Current topics and further information

Soil Aggregatomics

We developed the concept of Aggregatomics to study soil aggregates as functional biological entities. These entities, which are dynamic in space and time, control the flow of energy and substrates in soils.

Linking structural and functional diversity of soil microorganisms

Already one single gram of soil harbors more than 1,000 different bacteria. In addition there are archaea and fungi. How important is this huge microbial diversity for soil functions?

Importance of soil organic matter for microbial diversity

Organic matter is an important structural element of soils. How important is it to maintain a functioning microbial community and support microbial diversity?

Microbial diversity at different scales: From soil particles to the landscape

In order to understand the importance of microbial diversity and their changeability soils have to be investigated at different scales.

Interactions between soil microorganisms and organic pollutants

Agricultural, industrial and other human activities result in the introduction of organic pollutants into soil.

Effect of genetically engineered plants on soil microorganisms

Before genetically engineered plants are introduced to agricultural practice the ecological risks should be known.

Organic waste treatment (Composting, Biogas)

Microbial activities provide important means to degrade organic waste and generate usable end-products, i.e., bioenergy (“biogas”) or soil fertilizers.
