FOR 562: Dynamics of soil processes under extreme meteorological boundary conditions
Given the climate scenarios, we expect in future an increasing frequency of extreme meteorological boundary conditions that result in a higher frequency of drying/rewetting and freezing/thawing of soils. The latter might be especially relevant in higher elevation sites. Such drastic changes of the meteorological boundary conditions to soils, which occur irregularly and with varying intensity are obviously influencing the turnover of C, N and S in soils to a larger extend than previously thought. Our knowledge about the mechanisms and relevance of such conditions for soil processes is very limited, one reason for that is the lack of field experiments.
