Аннотация: We evaluated parameters (stock and flux) carbon, nitrogen and ash element cycling in the plant-soil system. The study was performed in arolla pine, Scots pine, Siberian larch, Norway spruce, aspen and birch plantations established on Kemchug upland, Chulym-Yenisei denudational plain, in 1968-1972. Young ecosystems (age class 2) that have developed under relatively similar environmental conditions have thus accumulated different amounts of organic and mineral matter in biomass and detritus, mainly due to differences in major woody species characteristics. All ecosystems are a net atmosperic carbon sink, with a pooling rate of 1.81-4.43 t C ha -1 yr -1. The sink (NEP) is made up by C accumulation in stand biomass production, vegetation detritus, and soil humus and accounts for 46-76% of the total C allocated in annual increment; the main componentt is net C flux to biomass. The rate of N-min flux from soil pool to NPP is in fact in balance with that soil N-min accumulation in the arolla pine, larch, spruce, and birch plots. In addition, the ecosystems are characterized by a transitional cycling regime evident through non-balanced controlling organic and mineral matter stored in "plant-soil" system blocks.

Аннотация: Between 72 and 88% of carbon (C) loss in forest litter decomposition returns to the atmosphere in the form of carbon dioxide. The share of water-soluble organic products does not exceed 3-4%. Between 8% under spruce and 25% under aspen and pine of the total C loss from litter organic matter goes to the formation of humus. Decomposition intensity of the dead organic matter on the soil surface is close to annual litterfall income (except under cedar). The specific rate of decomposition processes among the coniferous litters is minimum for cedar (167 mg C g-1 yr-1) and maximum for larch (249 mg C-1 yr-1). The spicific rate of decomposition of organic residues under aspen and birch canopies are 344 and 362 mg C-1 yr-1.

Аннотация: We defined catastrophic fire as a single high-severity fire that covers more than 10,000 ha and results in total consumption of litter, and humus layers and high tree mortality, or the simultaneous occurrence of several high-severity fires in a given region with a total area exceeding 10,000 km2. Fires on this scale can cause substantial economic, social and environmental effects, with regional to global impacts.

Южное Прибайкалье -- низовые пожары -- радиальный прирост деревьев -- напочвенный покров -- органогенные пирогенные горизонты почв
Аннотация: Проанализированы данные экспериментальных исследований по послепожарной динамике лесов в Южном Прибайкалье. Установлено, что низовые пожары подстилочно-гумусового вида в засушливые годы являются основным деструктивным фактором в динамике кедровых лесов. Воздействие низового огня сопровождается усыханием деревьев, а жизнеспособность выживших после пожаров кедров зависит от характера и тяжести огневых повреждений. Приведена характеристика нижних ярусов растительности и ее динамика под влиянием пожаров разной интенсивности. Показано негативное воздействие низовых пожаров на изменение запаса, качественного фракционного состава органогенных горизонтов почв и их химического состава. We examine the data from experimental investigations into the post-fire dynamics of Siberian stone pine forests in Southern Cisbaikalia. The analysis revealed that creeping fires of the litter-humus type in dry years constitute the main destructive factor in the dynamics of Siberian stone pine forests. Creeping fires involve desiccation of trees, while viability of Siberian stone pine trees that have survived the fire depends on the character and severity of fire-related tree injuries. We provide a characteristic of the lower layers of vegetation and its dynamics under the influence of fires of different intensities. It is shown that creeping fires have a negative influence on changes in reserves, qualitative fiber length distribution of organogenic soil horizons, and on their chemical composition.

Soil formation in the technogenic forest-steppe landscapes of the Nazarovskaya Depression in western Siberia

Аннотация: The soil formation was studied in the 21- to 35-year-old pine plantations created on the overburden dumps of the Nazarovskaya Depression without applying the material of the humus horizon. The surface technogenic formations under the pine plantations belong to the group of naturfabricats (surface formations devoid of the humus horizon and composed of natural substrate). The morphological characteristics, bulk chemical and particle-size compositions, and labile properties of the soils indicate that the accumulation and transformation of organic matter are dominant processes in the artificially planted forests. The accumulation of organic residues and destruction and humification are tightly related to the environmental conditions transformed by the technogenesis and conceal other processes forming the soil profiles. Quasizems created for agricultural production purposes were the objects of the study. They were formed by covering the technically planned overburden rocks with the material of humus layers. The thickness of the humus horizons of the quasizems varies greatly (25-64%); the variation of the humus reserves in them is 34-122%. Middle-profile horizons have not been formed by the present time.

Аннотация: Experimental data on the effect of surface fires on the organic matter transformation in the gray-humus soils of pine forests were obtained in the southwestern part of the Baikal region. The application of methods of thermal analysis (such as differential scanning calorimetry and thermogravimetry) made it possible to obtain qualitative and quantitative information about the decomposition (oxidation) of the components of the soil organic matter upon their heating. It was found that the organic matter content in the soils subjected to fires of high intensity decreased by 1.9 times in comparison with the control. In the litter horizons of the undisturbed soils, thermolabile components (mostly, oligo- and polysaccharides) comprised 61% of the organic matter, and the portion of thermostable components (aromatic compounds) was 39%. A significant decrease in the content of thermolabile components and an increase in the content of thermostable components (up to 62%) were observed in the organic matter of the postpyrogenic forest litter as a result of the charcoal formation during the fire.

Аннотация: The thermal degradation of organic matter was studied in cryogenic soils with methods of thermal analysis: differential scanning calorimetry and thermogravimetry (DSC and TG, respectively). The DSC curves of most of the samples within the temperature range from 221-247A degrees C to 600A degrees C were characterized by the presence of one wide exothermic peak (at 311-373A degrees C) with a shoulder (or without it) on the descending branch at a temperature of about 400A degrees C. This was connected mostly with the destruction of thermolabile compounds (oligo- and polysaccharides) and with the oxidation of low-aromatic complexes of plant residues and humus substances. Two exothermic peaks at 337-373A degrees C and 448-492A degrees C were found for some samples from the organic horizons. The high-temperature peaks were caused by the thermal destruction of lignin. The fraction of the thermolabile organic matter of the soil (237-261aEuro broken vertical bar 331-377A degrees C) reached 59-73% in the organic and 52-59% in the organomineral and mineral horizons.

Аннотация: The postfire transformation of the functional activity of the microbial cenoses and the main soil properties under mixed larch forests were studied in the lower reaches of the Angara River. It was shown that the intensity of the postfire changes in the population density, biomass, and activity of the microorganisms in the dark podzolized brown forest soil depended on the degree of burning of the ground cover and the surface litter during the fire. The maximum effects of the fire on the microbial cenoses were observed in the litter and the upper 5-cm-thick layer of the dark-humus horizon in the areas of intense burning. The postfire restoration of the structural-functional activity of the microbial cenoses was determined by the degree of transformation of soil properties and by the postpyrogenic succession in the ground cover. The microbial complexes of the dark podzolized brown forest soils under mixed larch forests in the studied region restored their functional activity after the fires of different intensities quicker than the microbial cenoses of the sandy podzols in the pyrogenic lichen-green-moss pine forests of the same zone.

Аннотация: The agrochemical properties and microbiological activity of the soils on dump rocks of different ages and degrees of cultivation in the area of the Borodinsk coal strip mine were studied. The technogenic soils of the dumps significantly differed from the native soils in their total nitrogen content. In the young soils (less than 5 years old), the total nitrogen was present in trace amounts; in the 20-year-old dumps, its content was lower than in the control soils by 2.5 times. It was found that a humus horizon 2-3 cm thick was formed on the surface of the dumps after 20 years regardless of the reclamation practice and that the intensity of the biological processes was comparable to that in the control soils, because the microbial complexes functioned under conditions typical for automorphic soils. It was shown that the ecophysiological status of the 3- to 10-year-old soils was unstable and their microbocenoses were at the development stage.

Аннотация: The estimates of the carbon pool in the organic matter of gray soils of the southern taiga, the intensity of destruction of its components, and participation of the latter in the formation of the mineralized carbon flux to the atmosphere are presented for different stages of succession of deciduous (birch) and coniferous (fir) forests. The carbon pool varies from 139.7 to 292.7 t/ha. It is distributed between phytodetritus, mobile and stabile humus (32, 19, and 49%, respectively). The intensity of the mineralization carbon flux to the atmosphere amounts to 3.93-4.13 t C per year. Phytodetritus plays the main role in the formation of this flux. In the soils under the forests studied, 4-6% of the carbon flux are formed owing to mineralization of the newly formed soil humus. In birch forests, 2-6% (0.1-0.2% of the humus pool in the 0-20-cm layer) is the contribution to the flux due to mineralization of soil humus. In fir forests, the mineralized humus is compensated by humus substances synthesized in the process of humification during phytodetritus decomposition.

Аннотация: In deep peat soils of forest-swamp ecosystems of West Siberia, the structural, dynamic and functional features of microbial complexes are estimated. Data on biological and chemical activity of peat deposits in the context of processes of organic matter decomposition and humus accumulation are presented. Quantitative indicators of microbiological mineralization and soil oligotrophicity are given, and their coefficients are calculated. The pool of microorganisms of a 8 meter thick layer is calculated for estimating the degree to which the forest-swamp soils are enriched with microflora.

Аннотация: The experimental data on the transformation of properties of soddy-deeply podzolic soils and raw humus burozems under fir forests defoliated by the Siberian moth Dendrolimus sibiricus are analyzed. In the first two months after the addition of Siberian moth excrements to the forest litter, the population of all ecological-trophic groups of microorganisms was shown to increase by 13 times, that of ammonifying phototrophs and microorganisms, taking part in humus mineralization, by 42 and 9 times, respectively. The leaching of water-soluble carbon from litters in forests defoliated by the Siberian moth was by 21-26% higher than that from litters of control ones. A year later, it was reduced to 14%. The content of exchangeable hydrogen and total acidity decreased, and the degree of base saturation increased. Within 5-6 years after the Siberian moth invasion, the transformation of physicochemical, chemical, and microbiological properties of soils was specified by succession development of the plant cover.

Ecological and biological features of soils in fir forests defoliated by the Siberian moth in the southern taiga subzone of middle Siberia

Аннотация: Experimental data are analyzed that concern the effect of zoogenic debris on the properties of soddy deep podzolic soils and raw-humus brown soils characteristic of southern taiga forests in the Yenisei region of Siberia. It is shown that the influence of excrements of Siberian moth larvae on the soil microflora lasts for two or, at most, three growing seasons. Zoogenic plant debris failing on the ground surface during tree stand defoliation is a short-acting but powerful stimulant of biological activity in the litter; hence, it has a considerable effect on soil properties. This effect is enhanced by changes in ecological conditions that occur upon defoliation. The influence of the cenotic factor on biogenic soil properties is manifested more strongly in the organogenic horizons. The communities of microorganisms involved in the nitrogen and carbon cycles are dominated by prototrophic forms in the normal fir forest and by pedotrophic forms in the forest defoliated by pests.

Аннотация: No accumulation of heavy metals was revealed in the deep (7.5 m) central zone of a eutrophic peatbog. Ti and W are the most dispersed elements in the peat deposit; Fe, Mo, and Mn are the most accumulated elements. The distribution of heavy metals during peat genesis depends on the quality of sorption humus barriers, and the redox zonality of the peat deposit and, hence, is indicative of the redox stages of boo evolution. Mo is a universal indicator element; its distribution in the peat profile clearly differentiates the redox conditions in both oxidative and reductive environments.

Аннотация: Slowed-down destructive processes in forest ecosystems of the northern taiga shift the contribution to the main carbon pool in soil from the slowly mineralizable organic matter or proper soil humus (17.7 t C/ha) toward the easily mineralizable fraction of organic matter, which is the most sensitive to any impact (38.1 t C/ha). The latter includes labile (26.9 t C/ha) and mobile (11.2 t C/ha) forms of organic matter. The microbial mass accounts for 3.6-4.9% of the total carbon pool in the soil.

Аннотация: Natural colonization of the steppe by forest vegetation is often observed in the contact zone between forest and steppe communities in northern Mongolia. Such successions appear owing to cyclic changes in the climate humidity. It was shown that morphological features of noncalcareous chernozems and their dynamic properties (pH, total exchangeable cations, humus composition) change under the influence of forest vegetation. These changes, however, are insufficient for attributing such chernozems to a new category.

Аннотация: Natural fires on forest bogs significantly affect all the groups and fractions of peat organic matter. The type and intensity of the fires are responsible for the depth of the pyrogenic transformation of peat. In the course of thermal destruction of peat organic matter, humus substances (humic acids in particular) are accumulated, which leads to changes in the type of humus; the humus reserves may increase by 1.5-8 times. Several ways of the formation of humus components related to the intensity of a fire are suggested. The regressive evolution of bog ecosystems caused by fires is a reversible process. The humus status of pyrogenically transformed horizons and their morphology are preserved within the peat deposit as a relic characteristic of the discrete metamorphosis of the soils.

Аннотация: In the litters (peaty, weakly decomposed, and strongly decomposed) of bog birch forests, the biochemical transformation of plant material includes several discrete stages. The best prediction of the decomposition stages is the set of indices characterizing the humus status of the soils: the C/N ratio, (I HA pound + I FA) pound/C(polysaccharides), and the contents of humic and fulvic acids of fraction 1 in the groups of plant debris of different sizes. The discrimination of the litters according to the level of the biochemical transformation of the organic residues was observed when using the (I HA pound + I FA) pound/C(polysaccharides) ratio, which is 6.3 in the peaty litter and 11.2 and 18.4 in the weakly decomposed and strongly decomposed litters, respectively. The biochemical classification of litters in the bog birch forests is in agreement with the morphological classification of litters.
