Data integration and modelling (WG DIM)

Contact: Holger Pagel ( and Damien Finn (

In order to understand the roles of soil physico-chemical and biological factors in energy and matter turnover, the SoilSystems projects will generate a wide range of data. Joint use and exchange of measurements and data across these projects will support linking complementary experimental evidence and thus maximize the use of information within the SoilSystems data space. The joint data set will support process-based modeling, which allows for the testing of hypotheses related to energy dissipation and matter turnover on quantitative grounds. WG DIM coordinates the data-model nexus in SoilSystems by addressing the following aims:

  • Identify and leverage synergies within SoilSystems projects to better integrate experiments and modeling
  • Coordinate the exchange and interpretation of data between experimental approaches and modeling
  • Harmonize the processing of energetic, mass balance, and taxon abundance data between experimental projects and the data used for models (in collaboration with the other SoilSystems working groups)
  • Support the implementation of the data management center in developing metadata templates for central data storage

Soil Functional Complexity in Space and Time

Contact: Christian Poll ( and Kenton Stutz (

The SPP explores soil as a system of energy and matter exchanges between organisms and their surroundings from a thermodynamic perspective. This WG investigates more closely the role of complexity and heterogeneity in soil systems and their functions. For instance, various soil functions are emergent properties of diverse soil communities and their interactions with and within a spatially heterogeneous and temporally variable environment of soil minerals, organic matter, pore space, and aggregates. We welcome all who are interested to regular meetings and seminars to exchange results of different approaches, collaborate on new analytical methods of heterogeneity and complexity, and synthesize new understanding on the functioning of complex adaptive soil systems.
