Abstract
The soil body is the largest terrestrial pool of organic carbon globally. Lately, research related to soil organic carbon has been a main focus worldwide, motivated by the potential the soil inhabits to become a manageable sink for atmospheric carbon dioxide and thus to mitigate climate change and the known benefits of increased soil organic carbon for the functioning of soils. Here, challenges are highlighted for soil organic carbon research that we are currently facing. Knowledge on soil organic carbon dynamics in the soil system is briefly reviewed, followed by an elaboration on how soil organic carbon dynamics and soil organic carbon stocks have been modelled in space and time and where modelling needs to go.
