Abstract forest 40 = ± kg m - 2, SOC forest 130 = ± kg m - 2 and SOC pasture = ± kg m - 2). However, including the additional carbon of the organic horizons in the forest, reaching up to 1.7 kg m - 2 in the 55-year old forest, resulted in an increase in the overall SOC stocks following afforestation. We found that the soil C: N ratio in the mineral soil increased in the topsoil (0–5 cm) with increasing forest stand age, from 11.9 ± ± C: N ratio with increasing depth in all forest stand ages. This suggests that litter-derived organic matter (C: N from 35.1 ± ± cm) of the profiles. Due to the high root C: N ratio (pasture 63.5 ± ± ± C: N ratios, as well as on SOC accumulation in the mineral soil. These results suggest that, although afforestation does not change the SOC stock in the mineral soil, there is an apparent alteration in the SOM dynamics through changes in the litter composition caused by the vegetation shift. We conclude that, at our study site, spruce afforestation on a former subalpine pasture does not change the total SOC stock and that, consequently, there is no additional SOC sequestration on a decadal to centennial scale.
