Simulation of soil organic carbon changes in Slovak arable land and their environmental aspects
The RothC-26.3 model was applied for long-term modelling (1970-2007) of the soil organic carbon (SOC) stock in the topsoil of croplands of Slovakia. Simulation results show a gradual increase in the SOC stock in the first phase of modelling (1970-1995) mainly due to higher carbon input in the soil....

Summary: | The RothC-26.3 model was applied for long-term modelling (1970-2007) of the soil organic carbon (SOC) stock in the topsoil of croplands of Slovakia. Simulation results show a gradual increase in the SOC stock in the first phase of modelling (1970-1995) mainly due to higher carbon input in the soil. A significant linear correlation (r = 0.4**, n = 275) was found between C input and the final simulation of SOC stock. A close relationship between the SOC stock and soil production potential index representing the official basis for soil quality assessment in Slovakia was also determined and a polynomial relationship was found. It describes the relation at the 95% confidence level. In conclusion, changes in the SOC stock dynamics important for sustainable use of soils could be influenced positively or negatively by political decisions concerning the soil management. Moreover, the soil production potential index can be used as soil quality information support for such decision-making. |
