Organic carbon stocks and sequestration rates of forest soils in Germany.

Grüneberg E, Ziche D, Wellbrock N - Glob Chang Biol (2014)

Bottom Line: We identified the organic layer C pool as stable although C was significantly sequestered under coniferous forest at lowland sites.The applied uncertainty analyses in this study link the variability of strata with measurement errors.In accordance to other studies for Central Europe, the results showed that the applied method enabled a reliable nationwide quantification of the soil C pool development for a certain period.

Relation between the bulk densities of the first/second (I/II) National Forest Soil Inventory (NFSI) in respect to the newly assigned soil groups (NSG). Bars and error bars represent means and standard errors, respectively. Numbers in the legend represent the newly assigned soil groups (cf. Table1).

fig05: Relation between the bulk densities of the first/second (I/II) National Forest Soil Inventory (NFSI) in respect to the newly assigned soil groups (NSG). Bars and error bars represent means and standard errors, respectively. Numbers in the legend represent the newly assigned soil groups (cf. Table1).

Mentions: The bulk density showed a high variability among the soil groups ranging from 0.30 ± 0.02 (NSG 16) to 1.11 ± 0.01 g cm−3 (NSG 1) in the upper depth increment (Fig.5). With increasing depth the bulk density increased, whereas the lowest increment revealed values between 0.57 ± 0.04 (NSG 16) and 1.48 ± 0.02 gcm−3 (NSG 6). We could further show that the bulk density in the 0–5 and 5–10 cm increments has changed significantly since the NFSI I (anova; P < 0.05). We further detected different bulk densities in all depth increments among soil groups (anova; P < 0.001) as well as interacting class variables (anova; P < 0.001). We showed for the uppermost increment on nearly all substrates (NSGs 1, 3, 4, 6, 7, 9, 10, 12, 14, and 16) a significantly decrease in bulk densities with resampling (Tukey; P < 0.05). Decreasing bulk densities were found mainly on calcareous sites (NSGs 4, 7, 10, 12, and 15) in the lower depth increments (Tukey; P < 0.05).
