Soil organic carbon is an integral part of organic. It affects many soil functions and its content depends on the balance between carbon dioxide loss from the soil and the accumulation of organic matter. Soils represent the largest carbon storage on Earth, but their carbon storage capacity depends on the climate. In the future, we will see demographic and technological changes that will result in changes in greenhouse gas emissions, and these will increase temperatures. Models can be used to determine the impact of climate change on soil organic carbon. There are several different models that differ in terms of input and output data and the suitability for specific locations. The RothC model is considered to be relatively straightforward in terms of obtaining input data, and is best suited for grassland. The CarboSOIL model is best suited for modelling organic carbon in areas of the Mediterranean climate. It provides information on the change of organic carbon to a depth of 75 cm, while the CENTURY model, which is also suitable for the Mediterranean climate, simulates the carbon dynamics in the upper 30 cm soil. As input climate data, the models use the results of general circulation models, which are based on emission scenarios. The purpose of this graduation thesis is to review and compare soil organic carbon models and their forecasts.
