Assessing carbon stocks, C stock changes, and sensitivity analyses of factors affecting estimated C stocks in six Norwegian forest soils

Popis výsledku v původním jazyce

We assessed soil organic carbon (SOC) stocks and changes across six upland forest sites with 13 replicated plots, spanning bioclimatic regions from the boreonemoral to the northern boreal zone. The sites included three ICP Forests Level II plots in older coniferous stands and three long-term experiments focusing on thinning intensity, tree species effects (Norway spruce, Scots pine, silver birch), and mixtures of Norway spruce and downy birch, the latter two following clear-cutting. Repeated soil surveys spanned 9-34 years. SOC stocks in the organic LFH horizon ranged from 1.4 to 3.6 kg m-2, while total stocks down to 30 cm and 70-100 cm mineral soil depths ranged from 3.0 to 13.5 kg m-2 and 8.5 to 17.5 kg m-2, respectively. Annual SOC stock changes in the LFH horizon ranged from -106 to 111 g m-2 yr-1, with significant changes observed in five plots. Total SOC stock changes down to 15, 18 or 20 cm mineral soil depth ranged from -77 to 154 g m-2 yr-1, with significant increases detected in two ICP level II plots. Sensitivity analyses supported these findings but highlighted inconsistencies in sampling methods, hight spatial variability, and limited replicates, affecting estimates in the remaining 11 plots.
