Abstract
Objective
Soil organic carbon (SOC) in deeper soils may be more protected by mineral particles than SOC in shallower soils; thus, the vertical SOC distribution is closely related to the overall SOC stability. This study aimed to verify the relationship between the solubility temperature dependence of water extractable SOC fractions and their vertical distribution characteristics.
Methods
Soil samples collected from each soil horizon in natural dragon spruce (Picea asperata) and red birch (Betula albosinensis) forests were analyzed. Cold water-extracted organic carbon (CWEOC) and hot water-extracted organic carbon (HWEOC) were extracted at 20 °C and 80 °C, respectively. The sum of CWEOC and HWEOC was considered the water-extracted organic carbon (WEOC) content. The carbohydrate-C (Car-C) and phenolic-C (Phe-C) contents extracted by hot water were also determined.
Results
The CWEOC, HWEOC, Car-C, and Phe-C contents varied significantly (P < 0.001) among soil horizons. The WEOC/SOC ratio increased significantly from the decomposed organic (H-) horizon to the surface mineral (A-) horizon (P < 0.05) but was not significantly different among the surface (A-), the subsurface (B-), and the bottom (C-) mineral horizons (Brunisols, according to the Canadian Soil Classification System). In both forests, CWEOC/HWEOC increased from the H- horizon to the B- horizon but was not significantly different between the B- and C- horizons. The Car-C/Phe-C ratios in the mineral soil horizons were significantly higher than those in the H-horizon and litter.
Conclusions
The more water-soluble SOC fractions tended to be more distributed in the deeper horizons. Therefore, WEOC in mineral soils may be more stable than is generally believed.
