Table 4 C fluxes (t C ha− 1). NEP was calculated as the difference between the amount of net organic carbon absorbed from the atmosphere and the amount of heterotrophic respiration in the released soil respiration. Litter production refers to the amount of organic carbon injected clinically through litters

From: Organic carbon distribution and budget of dominant woody plant community in the subalpine zone at volcanic Jeju Island, Korea
