Biogeochemistry of Forest Soils

Last changed: 22 August 2018

We study the interactions between chemical, biological, geological and/or physical processes governing element cycling (e.g. carbon, nitrogen) in forest soils. For example we study greenhouse gas emissions, mineral weathering and nitrogen leaching.

Our research goals are to advance knowledge of:

  1. Biogeochemistry of forest soils in different environments (climate, soil type, etc.)
  2. Human impacts, such as land-use, management, climate change and nitrogen deposition on biogeochemical processes.

We are conducting research in the following areas:

Furthermore, the unit Biogeochemistry of Forest Soils is engaged in under- and postgraduate education and environmental monitoring. The unit is responsible for the Swedish Forest Soil Inventory and The national assessments of greenhouse gas emissions from land-use.
