Assessment of organic matter changes in the soil of the Brdo plot under different climate change scenarios through the Yasso07 model application

The forest soil can act as an important sink for CO2 and in that respect also appears in the national Kyoto reports, where a distinction is made between carbon accumulated in litter and organic soil horizons and carbon accumulated in mineral soil layers. There is a multitude of dynamic mod...
