Abstract The temperature and moisture response of heterotrophic soil respiration are crucial for a reliable prediction of carbon dynamics with respect to climatic changes. However, despite numerous studies there are many controversies and open questions. One objective of this thesis was to analyse the influence of different soil temperature and moisture response functions on the prediction of CO production and effluxes. For this 2purpose, soil temperature and moisture reduction functions of six soil carbon decomposition models (CANDY, CENTURY, DAISY, PATCIS, RothC, and SOILCO2) were implemented in the SOILCO2/RothC model.
