Core Research Unit: Chemicals in agro-ecosystems

The Core Research Unit: "NOM Dynamic and Chemicals" is devided into two subject areas:

Organic carbon compounds undergo chemical and biological conversions in the soil and show physico-chemical interactions with their different constituents. They thus significantly influence the soil's storage, filtering, buffer, degradation and inactivation functions.

The conversion of native carbon compounds themselves is governed by the respective microorganism community. The microorganisms produce and use different carbon pools in a dynamic process, which are responsible for the fate of environmental chemicals in soils, together with the mineral soil components.

The binding of these substances to soil components decisively influences their mobilization and immobilization capacity and thus bioavailability and transport performance.

The understanding of these processes is necessary, for example, for sensitively matching the application quantities of pesticides in precision farming. The diagram gives a survey of the dynamically proceeding processes in topsoil.
