We established a long-term field study in a sessile oak-turkey oak forest in Central Europe Hungary (Síkfokút Experimental Forest (SIK) to address how detrital quality and quantity control soil organic matter (SOM) accumulation and soil respiration. Due to the climate change the species composition of forest has been changing (Kotroczó et al., 2007), and the total leaf litter production has been slightly decreasing. According to our long-term litter manipulation field experiment, after a 5 year treating period, at the No Litter, No Root and No Input treatments the soil organic carbon, the soil pH, the soil enzyme activity (Fekete et al., 2007; Tóth et al., 2007; Kotroczó et al., 2006) and soil respiration decreased. If the average soil temperature raise by 2 oC at the dry SIK site, the soil respiration would increase by 22.1%. The increasing soil respiration could speed up the global warming by positive feedback mechanism.
