“…The results obtained generally coincide with previously published data for the soils of the spruce forests of the European Northeast [65][66][67], and in general for the soils of the Komi Republic [68] and Central Siberia [25,69,70]. According to a recent assessment of carbon and nitrogen reserves in the predominant soils of the Komi Republic, reserves range from 5.17 to 73.23 kg m −2 [68].…”

Fires play an important role in the modern dynamics of boreal ecosystems. The article presents the results of studying the effect of old fires on soils and soil organic matter (SOM) of native spruce forests that were last affected by fires in the previous 100 to 200 years. The studies were carried out in the European north-east of Russia (Komi Republic) and Central Siberia (Krasnoyarsk region). The objects of the study were typical Glossic Stagnic Retisol (Siltic, Cutanic). The time after the fire was determined by dendrochronological methods. Data on the content of water-soluble organic matter and densimetric fractions of soils were obtained; carbon and nitrogen stocks were calculated. The content of polycyclic aromatic hydrocarbons (PAHs) was established to characterize the effect of fires. Pyrogenic carbonaceous inclusions were morphologically diagnosed 200 years after the fire. In this regard, it is proposed to distinguish a “pyrogenic” subtype for soils with pronounced signs of pyrogenesis. Carbon stocks in soils of the Komi Republic varied from 5.7 to 15.7 kg C m−2, and soils of the Krasnoyarsk region had an accumulation of 6.9–12.5 kg C m−2. The contribution of the pyrogenic horizon Epyr to the total carbon and nitrogen stocks was 9–45%. It is suggested that pyrogenic carbon (PyC) can accumulate in light densimetric fractions (fPOM<1.6 and oPOM<1.6). The analysis of PAH content showed their high concentrations in the organic and upper mineral horizons of the studied soils (24 to 605 ng g−1). The coefficient FLA (fluoranthene)/(FLA+PYR(pyrene)) was the most useful to diagnose the pyrogenic origin of PAHs in the studied Retisols.

“…Because of the strong historic depletion and thus the potentially high SOC sink capacity, the priority should be in measurement and monitoring of SOC stock and fluxes in soils of the tropics (Lugo & Brown, 1993;Batjes and Sombroek, 1997), Sub-Saharan Africa (Akpa, Odeh, Bishop, Hartemink, & Amapu, 2016;Doumbia et al, 2009;Lykke et al, 2009;Saiz et al, 2012), and South Asia (Lal, 2004(Lal, , 2017. There is also need to quantify SOC stocks and fluxes for developed country regions such as Australia (Godde, Thorburn, Biggs, & Meier, 2016), Europe (Booth et al, 2005;Freibauer, Rounsevell, Smith, & Verhagen, 2004;Stolbovoi, 2002) and the United States (Lokupitiya et al, 2012). In addition to climate change, SOC stocks must also be linked to provision and delivery of other ecosystems services (Lal, Follett, & Kimble, 2003;Stringer et al, 2012), especially food, water, and biodiversity.…”

The global magnitude (Pg) of soil organic carbon (SOC) is 677 to 0.3-m, 993 to 0.5-m, and 1,505 to 1-m depth. Thus, ~55% of SOC to 1-m lies below 0.3-m depth. Soils of agroecosystems are depleted of their SOC stock and have a low use efficiency of inputs of agronomic yield. This review is a collation and synthesis of articles published in peer-reviewed journals. The rates of SOC sequestration are scaled up to the global level by linear extrapolation. Soil C sink capacity depends on depth, clay content and mineralogy, plant available water holding capacity, nutrient reserves, landscape position, and the antecedent SOC stock. Estimates of the historic depletion of SOC in world soils, 115-154 (average of 135) Pg C and equivalent to the technical potential or the maximum soil C sink capacity, need to be improved. A positive soil C budget is created by increasing the input of biomass-C to exceed the SOC losses by erosion and mineralization. The global hotspots of SOC sequestration, soils which are farther from C saturation, include eroded, degraded, desertified, and depleted soils. Ecosystems where SOC sequestration is feasible include 4,900 Mha of agricultural land including 332 Mha equipped for irrigation, 400 Mha of urban lands, and ~2,000 Mha of degraded lands. The rate of SOC sequestration (Mg C ha year ) is 0.25-1.0 in croplands, 0.10-0.175 in pastures, 0.5-1.0 in permanent crops and urban lands, 0.3-0.7 in salt-affected and chemically degraded soils, 0.2-0.5 in physically degraded and prone to water erosion, and 0.05-0.2 for those susceptible to wind erosion. Global technical potential of SOC sequestration is 1.45-3.44 Pg C/year (2.45 Pg C/year).

“…Chestnyck et al [1999] estimate storage in East European Russian tundra soils at 17.8 kg C m À2 . Stolbovoi [2002Stolbovoi [ , 2006 provide the estimates 26.9 kg C m À2 in soils of northern taiga and forest-tundra and 16.6 kg C m À2 in tundra soils. The current estimate of soil C storage for the Usa Basin lowlands (38.3 kg C m À2 ) is also slightly higher than the previous, methodologically alike, estimate by Kuhry et al [2002] of 36.0 kg C m À2 (calculated from the 2002 database for 1m in mineral soils and full peatland depth with alpine habitats excluded).…”

This study investigates landscape allocation and environmental gradients in soil organic carbon (C) storage in northeastern European Russia. The lowlands of the investigated Usa River Basin range from taiga with isolated permafrost to tundra vegetation on continuous permafrost. We compile and analyze databases on soil properties, permafrost, vegetation, and modeled climate. Mean soil C storage is estimated at 38.3 kg C m−2, with similar amounts in taiga and tundra regions. Permafrost soils hold 42% of the total soil C in the area. Peatlands dominate soil C storage with 72% of the total pool and 98% of permafrost C. Multivariate gradient analyses show that local vegetation and permafrost are strong predictors of soil chemical properties, overshadowing the effect of climate variables. This study highlights the importance of peatlands, particularly bogs, in bulk soil C storage. Soil organic matter stored in permafrost has higher C:N ratios than unfrozen material. Permafrost bogs constitute the main vulnerable C pool in the region. Remobilization of this frozen C can occur through gradual but widespread deepening of the active layer with subsequent talik formation or through more rapid but localized thermokarst erosion.
