IMPRS course 'Soil, soil biology and soil hydrology'

  • Beginn: 16.10.2023
  • Ende: 29.12.2023

The rationale of this module is to provide PhD researchers with a general idea of soil formation, life within the soil, the links to biogeochemical cycles, as well as transport processes.

Key integrating aspects (propositions, to be continued):

  • Everything is connected (i.e. the water, C, N, P and mineral cycles interact nowhere as closely as in the soil)
  • Time scales of the different interacting cycles (time of soil formation, vs. time of complete degradation of this years litter vs. time of complete exchange of water within the soil volume?)
  • Soil structure connects with biogeochemistry as well as water flow

Category: Core course
Credits: 0.2 per course day
