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.

technogenic surface formation -- replantozem -- reclamation -- coal dump -- assessment of the state

Аннотация: The dynamics have been studied of the ecological-functional parameters (EFP) of replantozems formed on the dumps of the Borodinskiy open-pit coal mine in the Kansk-Achinsk Coal Basin (55A degrees 52' N, 94A degrees 54' E) that were not involved into agricultural use during the first 30 years. The work was based on the integrated analysis of the agrochemical properties and the EFP, which characterized the state of the plant cover, the microbial cenoses, and the biochemical activity of the replantozems representing a chronological series (5, 20, and 30 years). Multicomponent plant communities were formed on the surface of the replantozems over the 30-year period. The filled horizon of the replantozems was slowly involved into the metabolic processes. The thickness of the biologically active layer did not exceed 10 cm. The microbial cenosis's functional activity was relatively stabilized, and the values of the microbial biomass and basal respiration approached the background ones only in the upper (0-5 cm) layer. The biochemical activity of the microorganisms agreed with the changes in the properties of the upper (0-10 cm) layer of the replantozems: the contents of the total nitrogen and humus increased, as well as the degree of the humic acids "maturity" and the concentration of the mobile phosphorus, while the alkalinity decreased.

    The influence of willow plantations and soil composition on the process of natural vegetation settlement at oil drilling sites in Western Siberia
/ V. N. Sedykh, V. V. Tarakanov, M. Y. Telyatnikov ; ed.: N. N. Lashinsky, N. I. Makunina // RESULTS AND PROSPECTS OF GEOBOTANICAL RESEARCH IN SIBERIA, DEDICATED TO : E D P SCIENCES, 2019. - Vol. 16: Conference on Results and Prospects of Geobotanical Research in Siberia (MAY 13-17, 2019, Novosibirsk, RUSSIA). - Ст.

Аннотация: Test cultures of various willow species were created in 1997 on a technogenic sandy site of one of oil deposits (62 degrees 46'18.36" N, 72 degrees 09'48.69" E). Sixty-five isolated plots, including various soil substrates (sand, peat, drilling wastes), were placed in the testing area of 684 m(2). Optimum combinations of substrate components were identified, and the tolerance of willow species to drilling wastes was revealed by the results of investigating 1-5-year cultures [1]. In 2016 we investigated the natural settlement of aborigine plants in this test plot. The willow cultures mortality was high according to short offspring vegetative lifetimes and the limitation of feed areas. However, willow cultures and soil reclamation stimulated a settlement of natural plant seedlings. The comparison of phytocenoses, which were formed in various experimental and "background" conditions, has allowed making some conclusions. 44 plant species are growing now in the experimental area. The least number of species is characteristic for pure sand and pure peat substrates, the greatest - for complex substrates with sand, peat and drilling wastes. Thus, the experimental willow cultures and partial soil reclamation accelerated the formation process of forest ecosystems that created a "plant oasis" on a deserted landscape of technogenic sand.

    Soil temperature in disturbed ecosystems of central siberia: Remote sensing data and numerical simulation
/ T. V. Ponomareva, K. Yu. Litvintsev, K. A. Finnikov [et al.] // Forests. - 2021. - Vol. 12, Is. 8. - Ст. 994, DOI 10.3390/f12080994 . - ISSN 1999-4907
Аннотация: We investigated changes in the temperature regime of post-fire and post-technogenic cryogenic soils of Central Siberia using remote sensing data and results of numerical simulation. We have selected the time series of satellite data for two variants of plots with disturbed vegetation and on-ground cover: natural ecosystems of post-fire plots and post-technogenic plots with reclamation as well as dumps without reclamation. Surface thermal anomalies and temperature in soil horizons were evaluated from remote data and numerical simulation and compared with summarized experimental data. We estimated the influence of soil profile disturbances on the temperature anomalies forming on the surface and in soil horizons based on the results of heat transfer modeling in the soil profile. According to remote sensing data, within 20 years, the thermal insulation properties of the vegetation cover restore in the post-fire areas, and the relative temperature anomaly reaches the level of background values. In post-technogenic plots, conditions are more “contrast” comparing to the background, and the process of the thermal regime restoration takes a longer time (>60 years). Forming “neo-technogenic ecosystems” are distinct in special thermal regimes of soils that differ from the background ones both in reclamated and in non-reclamated plots. An assumption was made of the changes in the moisture content regime as the main factor causing the long-term existence of thermal anomalies in the upper soil horizons of disturbed plots. In addition, we discussed the formation of transition zones (“ecotones”) along the periphery of the disturbed plots due to horizontal heat transfer. © 2021 by the authors.

Albedo -- Disturbances -- Monitoring -- Post-fire and post-technogenic landscapes -- Satellite data -- Surface temperature -- Thermal anomalies

Аннотация: A method for monitoring recovery process in post-fire and post-technogenic landscapes was proposed based on satellite data in wide spectral range including the infrared bands data. The spectral albedo in short-wavelength bands (MODIS band #1 and #2) was underestimated by 20–48% relative to the background in the first year after the wildfire and remained underestimated by 3–12% after 20 years of vegetation restoration. For the variant of post-technogenic plot with reclamation, the albedo value was corresponded to the dynamics in post-fire plots, while for post-technogenic dumps without reclamation the level of the albedo underestimation remained 45–60% throughout the observation period (> 60 years). A decrease in the spectral albedo of the surface in post-fire areas, due to destruction of on-ground vegetation, provokes excessive heating of surface and upper soil layer. Surface thermal anomalies were evaluated under conditions of changes in the heat-insulating properties of vegetation and ground cover. Temperature anomalies in post-fire plots (overestimation up to 30%) are typical for permafrost conditions of Siberia. Similar process was recorded for both natural (post-fire) and post-technogenic landscapes. Within 20 years of the fire, thermal insulation properties of the vegetation cover restore. Thus, the relative temperature anomaly has reached the background value of 3 ± 1%. In post-technogenic plots conditions are more “contrast” compared to the background, and restoration of the thermal regime takes significantly longer period (> 60 years). Forming “neo-technogenic ecosystems” are characterized with specific thermal regimes of soils compared to the background ones both for reclaimed and for non-reclaimed post-technogenic plots. In averaged, surface temperature has overestimated at least by 10–15% in post-technogenic plots. © 2021 Copyright for this paper by its authors.

Аннотация: Изучали мезотрофное болото, осушенное 25 лет назад (географические координаты 56°23′710″ N, 84°34′043″ E). В торфяных почвах (Histosols) средневзвешенная за сезон активность пероксидазы (базовый уровень) составила в режиме слабой гидромелиорации 14.4, умеренной – 21.9, интенсивной – 70 ед. (мл йода на 1 г сух. навески за 2 мин). Основная закономерность развития сезонных колебаний активности пероксидазы описывается полиномом второго порядка. Значения и знаки параметров параболического тренда показывают, что средняя активность пероксидазы еженедельно снижалась на 4.4, 7.6 и 15.2 ед. с еженедельным средним ускорением на 0.31, 0.59 и 1.54 ед. с июня по октябрь в режиме слабого, умеренного и интенсивного осушения соответственно. Сезонные колебания активности пероксидазы относительно базового уровня характеризуется июньским увеличением прироста, максимальным в слое 0–10 см. В июле наблюдается снижение темпов прироста: в режиме слабого и умеренного осушения процесс охватывает весь почвенный профиль в августе, в условиях глубокого осушения – в октябре. Активность фермента достоверно положительно связана с объемной влажностью и величиной рН, отрицательно – с окислительно-восстановительным потенциалом и разнонаправлено – с температурой почв. При оценке вклада условий почвенной среды в сезонную динамику пероксидазы создается эффект взаимозаменяемости экологических градиентов. Методом канонического анализа установлено, что индексы детерминации объясняют совокупное воздействие обсуждаемого множества на 52–74%, главным фактором, регулирующим сезонную активность пероксидазы, является гидротермический режим: в условиях слабого осушения в большей мере под воздействием температуры, интенсивного – влажности, умеренного осушения – влажности и температуры. Активность пероксидазы и глубина гумификации торфяных почв разной степени осушения взаимосвязаны на 87%.
We studied a mesotrophic swamp drained 25 years ago, in the northern part of the Ob and Tom rivers (geographical coordinates 56°23′710″ N, 84°34′043″ E). In forest peat soils (0–30 cm), the weighted average of peroxidase activity for the season (base level) was in the mode of weak hydro reclamation 14.4, moderate – 21.9, intensive 70 units (ml I/g of abs. dry sample in 2 min). Second-order parabola is a most adequate function of the main trend of the development of seasonal fluctuations in peroxidase activity. Numerical values and signs of the parabolic trend parameters show that from June to October, the average peroxidase activity decreased weekly by 4.4, 7.6 and 15.2 units with weekly average acceleration by 0.31, 0.59 and 1.54 units in the mode of weak, moderate and intensive drainage, respectively. The seasonal wave of peroxidase activity relative to the baseline level is characterized by a June increase in growth rates, the maximum in the 0–10 cm layer. In July, there is a decrease in the growth rate according to the depth of reclamation: in the mode of weak and moderate drainage the process already covers the entire soil profile in August, in conditions of intensive drainage – in October. The enzyme activity is significantly positively related with soil bulk moisture and pH, negatively – with redox potential and multidirectionally – with soil temperature. Environmental conditions act as duplicate parameters when assessing their contribution to the seasonal dynamics of peroxidase, creating the effect of interchangeability of environmental gradients. Canonical determination indices approximate the cumulative impact of the discussed set by 52–74%, depending on the depth of reclamation. Canonical weights show that the main factor regulating the seasonal activity of peroxidase is the hydrothermal regime. According to canonical correlations, in conditions of weak drainage, to a greater extent under the influence of temperature, intensive – humidity, moderate drainage – humidity and temperature. The differentiated contribution of peroxidase activity in the formation of the humus state of peat soils of different degrees of drainage was revealed
