Recent climate scenarios predict not only continued global Recent climate scenarios predict not only continued global warming but also strong changes in temperature and precipitation with unusual regional dynamics. This results in disturbance of interactions between soil organisms from macro-scale (rhizosphere, soil animals) to the level of soil microbial community responsible both for formation and for decomposition of soil organic matter. Soil organic carbon is an important component of the global carbon cycle, and changes in its accumulation and decomposition directly affect the carbon storage of terrestrial ecosystems and the global carbon balance. The ability of soils to store organic carbon depends to a great extent on climate and other related properties, in addition to land management in agricultural and forest soils. Available knowledge on soil organic carbon distribution, together with models that predict its evolution under different scenarios can be used to quantify the soil organic carbon stocks and forecast the effects of changes in land use, management and climate change on carbon emissions. Relevant topics will include: i) soil organic carbon dynamics under different land use management, climate or topographic conditions; ii) transformation mechanisms of soil organic matter caused by climate change; iii) the role of biotic-abiotic interactions in formation, maintenance and turnover of soil carbon stock; iv) models to quantify and predict the changes in soil organic carbon stocks.
