We hypothesised that variations in the amount of particulate organic matter (POM) can explain the C accumulation and also affects the C bound to mineral surfaces in soil under various vegetation. Methods: Soil samples were collected under three vegetation types of a 45-year-old experiment focused on initial soil development. Aggregate and density fractionations were combined to analyse C accumulation in large and small macro- and microaggregates as well as in free and occluded POM and mineral factions. Results: Deciduous forest soil accumulated the highest C content in the 0-5cm layer (43g C kg−1), whereas values in coniferous forest and arable soils were lower (30 and 12g C kg−1, respectively). The highest portion of C in arable soil was accumulated in the mineral fraction (80%), whereas 50-60% of the C in forest soils were in POM. More C was associated with minerals in deciduous forest soil (16g C kg−1 soil) than under coniferous forest and arable land (8-10g C kg−1 soil). Conclusions: Particulate organic matter explains most of the differences in organic C accumulation in soils developed during 45years under the three vegetation types on identical parent material. The C content of the mineral soil fraction was controlled by plant cover and contributed the most to differences in C accumulation in soils developed under similar vegetation type (forest).
