“…Such results are in accordance with previous studies (e.g. Kuznetsova et al, 2019; Labaz et al, 2014) which found a greater organic horizon thickness under coniferous than under broadleaved forests. The findings obtained through the sampling by FDL would indicate a positive effect of conifers on SOC storage (Figure 7c,d), but the ‘reading’ of the soil horizonation, as occurred with PGH sampling, allowed to assess that SOC under spruce forest was greatly stored in the organic horizons (Oe and Oa), where it accounted for about one‐third of the 0–30 cm C stock (Figure 6b), because of the recalcitrant nature of the spruce litter.…”

Soil organic carbon stock assessment in forest ecosystems through pedogenic horizons and fixed depth layers sampling: What's the best one?

In soil organic carbon (SOC) survey, the role of sampling approach is crucial and should not be underestimated. In this sense, the appropriateness of soil sampling by pedogenic horizons (PGH) and fixed depth layers (FDL) in forest is still a field of debate. The present work aimed to: (a) study the spatial variability of SOC concentrations and C stocks through PGH and FDL samplings in uneven-aged sweet chestnut, European beech and Norway spruce forests of the Apennine chain (Italy); (b) clarify the major advantages and drawbacks of sampling by PGH and FDL. In a representative area (18 Â 18 m) of each forest, a soil profile was investigated and eight additional sampling points were selected. The sampling was performed both by PGH and FDL (0-15 and 15-30 cm). For each forest, no SOC content and C stock differences in 0-30 cm soil depth were found between PGH (58.8 ± 5.3 g kg À1 and 103 ± 7 g ha À1 , respectively) and FDL (52.7 ± 4.3 g kg À1 and 117 ± 9 Mg ha À1 , respectively) sampling. However, under Norway spruce, PGH sampling pointed-out that C was mainly stored in Oe and Oa horizons (51.1 vs. 146 Mg ha À1 in the 0-30 cm layer). The higher coefficient of variation obtained when soil horizons were considered (from 19.2% to 72.8% for PGH and from 16.5% to 25.7% for FDL) suggested that PGH sampling preserved the information about the spatial variability within an ecosystem. The information loss about SOC vertical and spatial distribution would indicate the inability of FDL sampling to support decision-making plans addressed for sustainable use of soil resource.

Linking vegetation, soil biota, and soil carbon stocks in forests has a high predictive value. The specific aim of this study was to identify the relationships between vegetation, earthworms, and soil carbon stocks in nine types of forests dominating autonomous landscape positions in a coniferous–broadleaf forest zone of the European part of Russia. Mountain forests were selected in the Northwest Caucasus, while plain forests were selected in Bryansk Polesie and on the Moskva-Oka plain. One-way analysis of variance (ANOVA) and v-tests were used to assess the impact of different factors on soil C stocks. To assess the contribution of vegetation, litter quality, and earthworms to variation of carbon stocks in organic (FH-layer) and mineral layer (0–50 cm), the method of hierarchical partitioning was performed. The highest C stocks in the organic horizons were associated with the low-quality litter, i.e., with a low base saturation, high acidity, and wide C/N ratio. The highest soil C stocks in the mineral layers were found in mixed forests with the highest richness of plant species, producing litterfall of different quality. The С stock in the organic horizon was negatively related to the biomass of worms that process the litter, while the carbon stock in the mineral layers was positively related to the biomass of worms whose life activity is related to the mineral layers. These findings demonstrated the substantial influence of plants producing a litter of different quality, and of earthworms, belonging to different functional groups, on soil С stocks in coniferous–broadleaf forests.

“…We collected soil samples for further quantification of heavy metal concentration in road-side, industrial, and residential areas of Moscow and Bolshoye Dumchino village (Orel region) to evaluate the spatial variations in heavy metal soil contamination connected to urbanization and local land utilization (Fritz, 2017). Soil carbon sequestration plays an important role in mitigating the anthropogenic increases in atmospheric carbon dioxide concentrations (Kuznetsova et al, 2019).…”

This paper presents the study of toxicological state of the soil. It shows ecological and microbiological properties of the soil mantle in the areas of technological environmental impact and evaluates changes in the number of soil microorganisms as a result of toxic contamination of urban soil at different distances from the Moscow loop highway, and also as a result of dumping aluminum foundry slag in Orel region. Soil-inhabiting invertebrates species composition was evaluated at different soil contamination conditions. It was proven that the state of microbiocenosis changes depending on the intensity and character of the anthropogenic impact. It was established that soil fermentation and microbiological activity changes depending on the value of the cumulative heavy metals’ build-up coefficient. Study of interelement ties between the heavy metals concerned showed that they too may have the same anthropogenic origin regardless of their sources of origin. Pollution index indicates medium to high level of soil contamination in explored urban territories where vehicle emission is the main source of pollution, and dangerously high contamination of light-gray soil in the small settlement impacted by a nearby slag disposal site.
