modelling carbon dynamics in arable soils: mainly based on long term observations of carbon
dynamics the impact of site conditions and management on soil organic matter
is modelled in order to predict effects on soil functions and ecosystem services
impact of soil tillage to soil functions: based on selected experimental results the effect of different soil tillage systems on turnover conditions and matter cycling is studied in order to find effective modelling approaches
regionalisation of turnover processes: comparative studys on different soil map scales will provide
solutions for an improved model parametrisation procedure
current reasearch activities
monitoring of basic soil state variables on the experimental site in Bad Lauchstädt
use the CCB model to predict SOC storage and N-fluxes for arable sites in Saxony

CIPS: a recently developed model of the carbon turnover taking into account soil structure effects that runs as an CANDY add-on
CCB: a strongly simplified carbon turnover model with the same theoretical background like CANDY but running in annual time steps for average climate conditions
