Název v původním jazyce

Soil carbon inventories and carbon-13 on a latitude transect in Siberia

Popis výsledku v původním jazyce

We present soil organic carbon (SOC) inventories and carbon isotope compositions from over 900 samples collected in areas of minimally disturbed mature vegetation on freely drained soils (excluding peatlands) on a 1000 km transect along the Yennisey River, central Siberia. Carbon inventories over 0-30 cm depth range widely from 1.71 to 7.05 kg m-2. While an effect of changing climate or vegetation along the transect cannot be ruled out, the observed differences in SOC inventories are largely the resultof variations in mineral soil texture, with inventories in fine-textured soils being approximately double those in coarse-textured soils. The ?13C values of SOC in the 0- 5 cm interval ranged from -26.3 to -28.0#, with ?13C values for the 5-30 cm interval being 0.9#0.8# (1?) enriched in 13C relative to the 0-5 cm samples. The average ?13C value for the 0-5 cm interval for all samples was -27.1#0.6#(1?) and for the full 0-30 cm interval the average was -26.5#0.5# (1?). In general, ?13C va
