“…The data on SOC stocks in the 0-70 cm layer of humus-peaty soils are also given there, measuring at 40.6 kg × m −2 . Previously, studies of SOC stocks in the 0-10 cm soil layer were already conducted for this area by spatial modeling using remote sensing data, but these studies were conducted without taking into account the genesis of soils and the degree of their anthropogenic disturbance [6]. It was shown that in a plot or carbon polygon of more than 150 ha, SOC stocks in the 0-10 cm layer varied from 1 to more than 9 kg × m −2 [6].…”

It was shown that in a plot or carbon polygon of more than 150 ha, SOC stocks in the 0-10 cm layer varied from 1 to more than 9 kg × m −2 [6]. According to our data (Figure 4), when conditionally dividing the studied soils into undisturbed (podzol), postagrogenic (agro), and bog (peat) soils, SOC stocks in the 0-10 cm layer are not statistically different between undisturbed sod-podbur and postagrogenic agrozems.…”

“…According to the latest estimates, the CO 2 absorption potential for carbon polygons and farms in Russia is 3700 ± 1900 Kt CO 2 × year −1 . The "Ladoga" carbon polygon is located in the Leningrad Region in the boreal coniferous forests zone; it has not yet entered the global network, but research is already actively underway [4][5][6].…”

“…For the territory of the "Ladoga" Carbon Supersite, initial assessments of soil organic matter stabilization rate and carbon stocks in the 0-10 cm layer based on remote sensing data [4,6] were performed earlier, and a project concept for its functioning was developed [5]. The vegetation cover on the territory of the monitoring site was described in a fragmentary sense [5].…”

The global climate crisis forces mankind to develop carbon storage technologies. “Ladoga” carbon monitoring site is part of the Russian climate project “Carbon Supersites”, which aims to develop methods and technologies to control the balance of greenhouse gases in various ecosystems. This article shows the condition of soil and vegetation cover of the carbon polygon “Ladoga” using the example of a typical southern taiga ecosystem in the Leningrad region (Russia). It is revealed that soils here are significantly disturbed as a result of agrogenic impact, and the vegetation cover changes under the influence of anthropogenic activity. It has been found that a considerable amount of carbon is deposited in the soils of the carbon polygon; its significant part is accumulated in peat soils (60.0 ± 19.8 kg × m−2 for 0–100 cm layer). In agrogenically disturbed and pristine soils, carbon stocks are equal to 12.8 ± 2.9 kg × m−2 and 8.3 ± 1.3 kg × m−2 in the 0–100 cm layer, respectively. Stocks of potentially mineralizable organic matter (0–10 cm) in peat soils are 0.48 ± 0.01 kg × m−2; in pristine soils, it is 0.58 ± 0.06 kg × m−2. Peat soils are characterized by a higher intensity of carbon mineralization 9.2 ± 0.1 mg × 100 g−1 × day−1 with greater stability. Carbon in pristine soils is mineralized with a lower rate—2.5 ± 0.2 mg × 100 g−1 × day−1. The study of microbial diversity of soils revealed that the dominant phyla of microorganisms are Actinobacteria, Bacteroidetes, and Proteobacteria; however, methane-producing Archaea—Euryarchaeota—were found in peat soils, indicating their potentially greater emission activity. The results of this work will be useful for decision makers and can be used as a reference for estimating the carbon balance of the Leningrad region and southern taiga boreal ecosystems of the Karelian Isthmus.
