“…In both cases, nonsignificant differences in each depth increment summed to significant differences in the total soil profile. Significantly higher C and N pools in deeper layers of graminoid soils could be due to buried surface horizons following loess deposits, as described by Ping et al (1997), or nutrient leaching to deeper soil layers (Falsone et al 2012). While we did not observe buried organic horizons, soil layers from core extractions could not be reconstructed with confidence.…”

Shrub species are expanding across the Arctic in response to climate change and biotic interactions. Changes in belowground carbon (C) and nitrogen (N) storage are of global importance because Arctic soils store approximately half of global soil C. We collected 10 (60 cm) soil cores each from graminoid- and shrub-dominated soils in western Greenland and determined soil texture, pH, C and N pools, and C:N ratios by depth for the mineral soil. To investigate the relative chemical stability of soil C between vegetation types, we employed a novel sequential extraction method for measuring organo-mineral C pools of increasing bond strength. We found that (i) mineral soil C and N storage was significantly greater under graminoids than shrubs (29.0 ± 1.8 versus 22.5 ± 3.0 kg·C·m−2 and 1.9 ± .12 versus 1.4 ± 1.9 kg·N·m−2), (ii) chemical mechanisms of C storage in the organo-mineral soil fraction did not differ between graminoid and shrub soils, and (iii) weak adsorption to mineral surfaces accounted for 40%–60% of C storage in organo-mineral fractions — a pool that is relatively sensitive to environmental disturbance. Differences in these C pools suggest that rates of C accumulation and retention differ by vegetation type, which could have implications for predicting future soil C pool storage.

“…Ussiri & Johnson () found both redistribution of C and changes in C compounds throughout the mineral soil profile in an experiment comparing a 15‐year‐old and undisturbed forest. A study on the mechanics of C movement through the podzol soil profiles in Siberian clear‐cut vs. undisturbed forests found higher proportions of fulvic acids throughout the mineral soil profile after clear‐cutting (Falsone et al ., ). Aluminum and iron, characteristic leachates in the podzolization process, were also mobilized by clear‐cutting (Falsone et al ., ).…”

It is possible, however, for C additions to mineral soil layers to create a priming effect, whereby stable, pre-existing C is degraded when a labile energy source is added to the C-poor system (Fontaine et al, 2007).…”

Harvesting forests introduces substantial changes to the ecosystem, including physical and chemical alterations to the soil. In the Northeastern United States, soils account for at least 50% of total ecosystem C storage, with mineral soils comprising the majority of that storage. However, mineral soils are sometimes omitted from whole-system C accounting models due to variability, lack of data, and sample collection challenges. This study aimed to provide a better understanding of how forest harvest affects mineral soil C pools over the century following disturbance. We hypothesized that mineral soil C pools would be lower in forests that had been harvested in the last one hundred years vs. forests that were >100 years old. We collected mineral soil cores (to 60 cm depth) from 20 forest stands across the Northeastern United States, representing seven geographic areas and a range of times since last harvest. We compared recently harvested forests to >100-year-old forests and used an information theoretic approach to model C pool dynamics over time after disturbance. We found no significant differences between soil C pools in >100-year-old and harvested forests. However, we found a significant negative relationship between time since forest harvest and the size of mineral soil C pools, which suggested a gradual decline in C pools across the region after harvesting. We found a positive trend between C : N ratio and % SOM in harvested forests, but in >100-year-old forests a weak negative trend was found. Our study suggests that forest harvest does cause biogeochemical changes in mineral soil, but that a small change in a C pool may be difficult to detect when comparing large, variable C pools. Our results are consistent with previous studies that found that soil C pools have a gradual and slow response to disturbance, which may last for several decades following harvest.

Clear-cutting means forest removal (stems only) and is the most common type of forest harvesting but undoubtedly has a negative impact on the C budget in soils. This work aimed to describe responses of soil organic matter (SOM) in the mixed coniferous forest following the removal of trees under temperate climate conditions in lowland and mountain regions in southwestern Poland. Investigated soils are described as Brunic Arenosols derived from sand with an average content of total organic carbon (TOC) in the Oa-horizons of 244 gÁkg À1 in the lowland and Dystric Cambisols derived from gneiss; the average content of TOC in the Oa-horizons in the mountain regions was 309 g.kg -1 . Analyzed soils were very acidic in the both regions (pH 2.7-3.5 in the topsoil). In the experiment, two replicated soil profiles were located on each site, both taken after clear-cutting and without any harvesting. Humic fraction was isolated from Oa-and A-horizons; differences between investigated objects were checked with a significance p < 0.05, (n = 16). Using the instrumental analysis, like electron paramagnetic resonance (EPR), proton nuclear magnetic resonance ( 1 H NMR), and Fourier transformed infrared (FTIR) spectroscopy applied to isolated humic fractions, it has been found that clear-cutting alters C cycling and accelerates decomposition in the forest floor, leading to loss of humic fractions in the investigated soils. In the mountain forests, the more labile, low-molecular-weight fulvic fraction decreased as the effect of harvesting practice by 30% in Oa-horizon and by 54% in A-horizon. The analysis of stable radicals by EPR showed a decrease in radical concentration observed for humic acids (HA) from mountain clear-cut areas compared to the undisturbed forest. Results presented in this article have proved there is less aliphatic character of HA molecules from the lowlands, compared to the mountain forest as the effect of clear-cutting. Changes in plant cover observed as a consequence of deforestation lead to the decrease in concentration of humic fractions with different solubility properties.
