SUMMARY

Organic soils play a significant role in the climate system. In this study fen soils from Northeastern Germany were investigated concerning aspects of the soil carbon balance. Due to clarity reasons this paper is separated into two parts.

(A) Relations between the decomposition of radicell peat (von-Post-method) and contents of soil organic matter (SOM) and soil organic carbon (SOC) were identified and quantified. High negative correlations between the degree of decomposition and SOM and SOC contents were proved.

(B) Conversion factors from SOC to SOM were investigated referring to different levels of SOM and SOC contents. The calculated values ranged between 1.7 and 2.1.
