Soil nitrogen dynamics in a larch forest, Central Siberia : A short review of preliminary results

Hobara [и др.] // Symptom of environmental change in Siberian permafrost region: proceedings of the International symposium of JSPS core to core program between Hokkaido university and Martin Luther university Halle-Wittenberg in 29-30 November 2005, Sapporo, Japan. - Sapporo : Hokkaido University Press, 2006. - С. 109-111. - Библиогр. в конце ст.
Аннотация: Surface soils (organic layer and 0-10 cm mineral soil) from larch forests, Central Siberia, had small pool size of soil inorganic N, while higher values can be observed especially in organic layer in N fertilized sites. Annual leachate of inorganic N was also small before N fertilization, while greater values were observed beneath organic layer in high N site after fertilization. Thus, N treatment seems to stimulate inorganic N dynamics of soil surface, and it may consequently lead to stimulation of lower soils. Dissolved organic nitrogen (DON) was the most important N form constantly supplying dissolved N to soil circumstances in this site, suggesting a possibility of organic N to control on ecosystem processes in these forests.

Аннотация: Within- and among-population diversity of Gmelin larch Larix gmelinii (Rupr.) Rupr. from Evenkia was inferred from data on 17 genes determining allozyme diversity of ten enzymes. More than 50% of the genes proved to be polymorphic. On average, each tree was heterozygous at 9.2% genes. Heterozygosity expected from the Hardy-Weinberg proportions was higher, 12.5%. A deficit of heterozygous genotypes was observed in all populations under study and attributed to inbreeding. With Wright's F statistics, average individual inbreeding was estimated at 26.6% relative to the population (F-IS) and at 27.8% relative to the species (F-IT). The greatest deficit of heterozygosity was observed for the youngest population II. Within- population variation accounted for more than 98% of the total variation, while the contribution of among-population variation was 1.66%. Genetic distance between populations varied from 0.0025 to 0.0042, averaging 0.0035.

Embryonal development of Siberian pine (Pinus sibirica Du Tour) with the annual cycle of ovulate cone development in the Western Sayan mountains

Pinus sibirica -- acceleration -- bud -- shoot -- morphogenesis of ovulate cone -- embryological structures
Аннотация: Morphological and cytoembryological studies of unique forms of Siberian pine (Pinus sibirica Du Tour) with the annual cycle of ovulate cone development were carried out. The morphogenesis of female shoots in these anomalous trees with the annual cycle of development was shown to provide for an accelerated development and very rapid growth of megastrobili and accelerated formation of reproductive structures. Cytoembryological studies of ovules in these trees showed significant shortening of the free-nuclear stage of gametophyte development (up to 3 weeks instead of one year) and ultra-early formation of archegonia and egg cells. However, no fertilization of egg cells and the development of embryos occur in the anomalous forms; the egg-cell nucleus divides in the haploid state. Developing seeds are formed without embryo. The author hypothesizes that the acceleration of embryo development in the anomalous pine trees is caused by enhanced hormonal, carbohydrate, and nitrogen metabolism in ovule tissues.

Trees tell of past climates: but are they speaking less clearly today?
[Text] / K. R. Briffa [et al.] // Philos. Trans. R. Soc. Lond. Ser. B-Biol. Sci. - 1998. - Vol. 353, Is. 1365. - P65-73, DOI 10.1098/rstb.1998.0191. - Cited References: 34

Аннотация: The annual growth of trees, as represented by a variety of ring-width, densitometric, or chemical parameters, represents a combined record of different environmental forcings, one of which is climate. Along with climate, relatively large-scale positive growth influences such as hypothesized 'fertilization' due to increased levels of atmospheric carbon dioxide or various nitrogenous compounds, or possibly deleterious effects of 'acid rain' or increased ultra-violet radiation, might all be expected to exert some influence on recent tree growth rates. Inferring the details of past climate variability from tree-ring data remains a largely empirical exercise, but one that goes hand-in-hand with the development of techniques that seek to identify and isolate the confounding influence of local and larger-scale non-climatic factors. By judicious sampling, and the use of rigorous statistical procedures, dendroclimatology has provided unique insight into the nature of past climate variability, but most significantly at interannual, decadal, and centennial time-scales. Here, examples are shown that illustrate the reconstruction of annually resolved patterns of past summer temperature around the Northern Hemisphere, as well as some more localized reconstructions, but ones which span 1000 years or more. These data provide the means of exploring the possible role of different climate forcings; for example, they provide evidence of the large-scale effects of explosive volcanic eruptions on regional and hemispheric temperatures during the last 400 years. However, a dramatic change in the sensitivity of hemispheric tree-growth to temperature forcing has become apparent during recent decades, and there is additional evidence of major tree-growth (and hence, probably, ecosystem biomass) increases in the northern boreal forests, most clearly over the last century. These possibly anthropogenically related changes in the ecology of tree growth have important implications for modelling future atmospheric CO2 concentrations. Also, where dendroclimatology is concerned to reconstruct longer (increasingly above centennial) temperature histories, such alterations of 'normal' (pre-industrial) tree-growth rates and climate-growth relationships must be accounted for in our attempts to translate the evidence of past tree growth changes.

Аннотация: Seedlings were grown in vitro from fertilized eggs and immature embryos of the Siberian stone pine. Cultivation of megagametophytes on a hormone-containing Murashige-Skoog medium from the egg formation until the globular embryo stage made it possible to manipulate fertilization and embryogenesis. Immature embryos are the most promising for in vitro cultivation. Their maturation and germination proceed within seven days of cultivation. When zygotic embryos were cultivated, adventitious buds were formed from cells at the cotyledon base and tips. When adventitious buds were subcultivated on a medium containing benzylaminopurine and naphthylacetic acid, organogenic callus and shoots were formed. Thus, cultivation of megagametophytes and embryos of the Siberian stone pine led to the completion of embryogenesis and formation of viable of seedlings.

Аннотация: Birch (Betula pendula Roth) growth within the Western Siberia forest-steppe was analyzed based on long-term (1897-2006) inventory data (height, diameter at breast height [dbh], and stand volume). Analysis of biometry parameters showed increased growth at the beginning of twenty-first century compared to similar stands (stands age = 40-60 years) at the end of nineteenth century. Mean height, dbh, and stem volume increased from 14 to 20 m, from 16 to 22 cm, and from ?63 to ?220 m3/ha, respectively. Significant correlations were found between the stands mean height, dbh, and volume on the one hand, and vegetation period length (rs = 0.71 to 0.74), atmospheric CO2 concentration (rs = 0.71 to 0.76), and drought index (Standardized Precipitation-Evapotranspiration Index, rs = -0.33 to -0.51) on the other hand. The results obtained have revealed apparent climate-induced impacts (e.g. increase of vegetation period length and birch habitat drying due to drought increase) on the stands growth. Along with this, a high correlation of birch biometric parameters and [CO2] in ambient air indicated an effect of CO2 fertilization. Meanwhile, further drought increase may switch birch stand growth into decline and greater mortality as has already been observed within the Trans-Baikal forest-steppe ecotone. © 2014 © 2014 Taylor & Francis.

Аннотация: To separate soil respiration (SR) to microbial and root component in related to N input difference, we established trenching plot, and measured SR at N fertilization plots (urea of 60 kg N ha–1 y–1) and controls in a larch forest in central Siberia. Soil temperature and moisture were not different among the plots. In contrast, SR (unit: mg CO2-C m–2 h–1) in July was higher in the fertilization plots (167 ± 55) than in control (106 ± 27), and decreased by 21 and 39 % after root cutting in control and N fertilization plots, respectively. We found N fertilization increased root respiration rather than microbial respiration.

Аннотация: The results of the integrated analysis of changes in the state of vegetation and soils (Cutanic Albeluvisol) at the different stages of natural forest regeneration (4-, 11- and 24-year-old felled areas) and in a mature fir forest of the short grass-green moss forest types in the northern part of the western slope of the Yenisei Ridge are presented. A dynamic trend of fir forests restoration to the formation of the structure characteristics of the initial forest types is shown to be performed through the stages of forest meadows and secondary short grass (forbs) and birch stands. The changes in vegetation are accompanied by the fast transformation of the soil properties towards the improvement of soil fertilization However, these changes are temporary. © 2015, Pleiades Publishing, Ltd.

Аннотация: Background: Maritime Antarctica is severely affected by climate change and accelerating glacier retreat forming temporal gradients of soil development. Successional patterns of soil development and plant succession in the region are largely unknown, as are the feedback mechanisms between both processes. Here we identify three temporal gradients representing horizontal and vertical glacier retreat, as well as formation of raised beaches due to isostatic uplift, and describe soil formation and plant succession along them. Our hypotheses are (i) plants in Antarctica are able to modulate the two base parameters in soil development, organic C content and pH, along the temporal gradients, leading to an increase in organic carbon and soil acidity at relatively short time scales, (ii) the soil development induces succession along these gradients, and (iii) with increasing soil development, bryophytes and Deschampsia antarctica develop mycorrhiza in maritime Antarctica in order to foster interaction with soil. Results: All temporal gradients showed soil development leading to differentiation of soil horizons, carbon accumulation and increasing pH with age. Photoautptroph succession occurred rapidly after glacier retreat, but occurrences of mosses and lichens interacting with soils by rhizoids or rhizines were only observed in the later stages. The community of ground dwelling mosses and lichens is the climax community of soil succession, as the Antarctic hairgrass D. antarctica was restricted to ornithic soils. Neither D. antarctica nor mosses at the best developed soils showed any sign of mycorrhization. Conclusion: Temporal gradients formed by glacier retreat can be identified in maritime Antarctic, where soil development and plant succession of a remarkable pace can be observed, although pseudo-succession occurs by fertilization gradients caused by bird feces. Thus, the majority of ice-free surface in Antarctica is colonized by plant communities which interact with soil by litter input rather than by direct transfer of photoassimilates to soil.

Аннотация: Cytoembryological research of the ovules in experiments with interspecific hybridization of Pinus sibirica (pollination be the pollen of P. koraiensis, P. armandii, P. parviflora, P. strobus, P. hokkaidensis, P. wallichiana, P. monticola, and P. Nembra) revealed that the development of megagametophytes occurred in them by the usual scenario and resulted in the formation of mature archegonia. Pollen successfully germinated on the nucellus of ovules. However, disturbances were observed in the process of male gametophyte development, and pollen tubes on the nucellus were not visible by the period of archegonia maturation. Fertilization was usually absent. The development of embryonic channel is determined by egg cell maturity. The only exception was the variant of the controlled pollination of Pinus sibirica x P. Nembra, in which the embryo has been formed.

Microbial stoichiometric flexibility regulates rice straw mineralization and its priming effect in paddy soil

Аннотация: Nitrogen (N) and phosphorus (P) availability plays a crucial role in carbon (C) cycling in terrestrial ecosystems. However, the C:N:P stoichiometric regulation of microbial mineralization of plant residues and its impact on the soil priming effect (PE), measured as CO2 and CH4 emission, in paddy soils remain unclear. In this study, the effect of soil C:N:P stoichiometry (regulated by the application of N and P fertilizers) on the mineralization of 13C-labelled rice straw and the subsequent PE was investigated in a 100-day incubation experiment in flooded paddy soil. N and P additions increased straw mineralization by approximately 25% and 10%, respectively. Additions of both N and P led to higher CO2 efflux, but lower CH4 emission. With an increase in the ratios of DOC:NH4 +-N, DOC:Olsen P, and microbial biomass C:N, 13CO2 efflux increased exponentially to a maximum. Compared with sole straw addition, exclusive N addition led to a weaker PE for CO2 emission, whereas exclusive P addition induced a stronger PE for CO2 emission. In contrast, CH4 emitted from native soil organic matter (SOM) was reduced by 7.4% and 46.1% following P and NP application, respectively. Structural equation models suggest that available N had dominant and direct positive effects, whereas microbial biomass stoichiometry mainly exerted negative indirect effects on PE. The stoichiometry of soil enzyme activity directly down-regulated CH4 emission from SOM. Microbes obviously regulate soil C turnover via stoichiometric flexibility to maintain an elemental stoichiometric balance between resources and microbial requirements. The addition of straw in combination with N and P fertilization in paddy soils could therefore meet microbial stoichiometric requirements and regulate microbial activity and extracellular enzyme production, resulting in co-metabolism of fresh C and native SOM. © 2018 Elsevier Ltd

Аннотация: Aerosols produced by wildfires are a common phenomenon in boreal regions. For the Siberian taiga, it is still an open question if the effects of aerosols on atmospheric conditions increase net CO2 uptake or photosynthesis. We investigated the factors controlling forest net ecosystem productivity (NEP) and explored how clouds and smoke modulate radiation as a major factor controlling NEP during fire events in the years 2012 and 2013. To characterize the underlying mechanisms of the NEP response to environmental drivers, Artificial Neural Networks (ANNs) were trained by eddy covariance flux measurements nearby the Zotino Tall Tower Observatory (ZOTTO). Total photosynthetically active radiation, vapour pressure deficit, and diffuse fraction explain at about 54-58% of NEP variability. NEP shows a strong negative sensitivity to VPD, and a small positive to f(dlf). A strong diffuse radiation fertilization effect does not exist at ZOTTO forest due to the combined effects of low light intensity, sparse canopy and low leaf area index. Results suggests that light intensity and canopy structure are important factors of the overall diffuse radiation fertilization effect.

Аннотация: Paddy soils have experienced intensive fertilization in recent decades. However, our understanding of the effects of fertilization on the carbon (C) cycle remains incomplete. In the present study, we investigated soil organic matter (SOM) decomposition in a 60-day incubation in response to N, P, K, Ca, and S addition to nutrient-limited paddy soil at three low and three high concentrations. High levels of nutrient addition decreased CO2 emission, qCO(2), and microbial biomass. CO2 emissions increased (12-17%) owing to low levels of nutrient addition, whereas it decreased (3-21%) in response to high levels of nutrient addition. Microbial biomass and nutrient turnover rates increased after low levels of nutrient addition. Positive priming effect occurs under nutrient-limited conditions owing to the stimulation of microbial biomass production after low amount of exogenous nutrient input. In contrast, high levels of nutrient addition decreased microbial biomass and net N mineralization. This high N, P, K, Ca, and S addition could satisfy the needs of microbial growth, thereby decreasing the dependency of the organisms on the original nutrients from SOM decomposition. Therefore, negative priming was observed after high-level nutrient addition. In conclusion, intensive fertilization (with N, P, K, Ca, and S) reduces SOM decomposition through increased microbial turnover in paddy soils, which might positively affect C sequestration.

Аннотация: We reviewed the recent publications on the nitrogen cycle and application of nitrogen fertilizers in forest ecosystems.

Аннотация: Rhizodeposition represents a readily available C and energy source for soil microorganisms, that plays an important role in the regulation of C and nutrient cycling in ecosystems and exerts a strong influence on C sequestration. The dynamics of rice rhizo-C in soils and its allocation to microorganisms during rice growth, as well as the effects of nitrogen (N-NH4 +) fertilization are poorly understood, particularly with respect to the initial uptake of rhizo-C by microorganisms and its utilization during the entire growth period. To assess these two processes, rice plants were grown in pots with or without N fertilization (0 and 225 kg N-NH4 + ha?1), and 13C incorporation into microbial groups was traced by phospholipid fatty acids (PLFAs) analysis within 6 h after 13CO2 pulse labeling. Labeling was performed at five growth stages: tillering, elongation, heading, filling, and maturation. 13C incorporated into soil microbial biomass C changed rapidly at the beginning of the study period, before elongation, but remained stable thereafter. 13C incorporation into rhizosphere and bulk soil microbial biomass was higher with than without N addition. This stimulation was likely due to the excessive increase in phytomass formation and root exudates after N fertilization and the increased assimilate C input into the soil. Structural equation modelling suggested that N fertilization strongly affected carbon transfer between rhizosphere and non-rhizosphere. Hence, N-NH4 + application may not only increase rhizo-C flow into microorganisms but it may also increase the effect of rhizosphere on bulk-soil microorganisms and subsequent processes related to soil C-cycling. © 2018 Elsevier B.V.

Assimilate allocation by rice and carbon stabilisation in soil: effect of water management and phosphorus fertilisation

Carbon sequestration -- Carbon stabilisation -- Paddy soil -- Rhizodeposition -- Soil aggregate size classes -- Soil density fractions
Аннотация: Background and aims: Water and nutrient management influences the allocation and stabilisation of newly assimilated carbon (C) in paddy soils. This study aimed to determine the belowground allocation of C assimilated by rice and the subsequent C stabilisation in soil aggregates and as mineral-organic associates depending on combined alternate wetting and drying (AWD) versus continuous flooding (CF) and P fertilisation. Methods: We continuously labelled rice plants in 13CO2 atmosphere under AWD versus CF water management, and at two P fertilisation levels (0 or 80 mg P kg?1 soil). The 13C allocation to soil and its incorporation into the wet-sieved aggregate size classes and density fractions of the rhizosphere and bulk soils were analysed 6, 14, and 22 days after the labelling was started (D6, D14, and D22, respectively). Results: Under both water regimes and P fertilisation levels, the proportion of photoassimilates was the highest in the silt- and clay-size aggregate classes and in the mineral-associated fraction. On D6 and D14, P fertilization resulted in smaller 13C incorporation into soil, independent of water management. In the rhizosphere soil, at D22, P fertilisation increased 13C incorporation over no P amendment in macroaggregates (>250 ?m) by 32% (AWD) and 42% (CF), in microaggregates (250–53 ?m) by 97% (CF), and in the silt + clay size class (<53 ?m) by 83% (CF). Further, P fertilisation led to larger 13C incorporation into the rhizosphere soil light fraction (75% at AWD and 90% at CF) and dense fraction (38% and 45%, respectively), and into the bulk soil macroaggregates (71% and 78%, respectively). Conclusions: Phosphorus fertilisation increased the contents of recent photoassimilates in soil aggregate classes with longer residence time as well as of the particulate organic matter with the continuation of plant growth. This positive response of the stabilisation of recent plant photosynthates in soil to P fertilisation can increase the potential of paddy soil for C sequestration. This potential is not limited by the introduction of alternate wetting and drying water-saving technique. © 2018, Springer Nature Switzerland AG.

Nitrogen fertilization modifies organic transformations and coatings on soil biogeochemical interfaces through microbial polysaccharides synthesis
/ X. Huang [et al.] // Sci. Rep. - 2019. - Vol. 9, Is. 1. - Ст. 18684, DOI 10.1038/s41598-019-55174-y

Аннотация: The soil-water interfaces (SWI) in soil pores are hotspots for organic matter (OM) transformation. However, due to the heterogeneous and opaque nature of soil microenvironment, direct and continuous tracing of interfacial reactions, such as OM transformations and formation of organo-mineral associations, are rare. To investigate these processes, a new soil microarray technology (SoilChips) was developed and used. Homogeneous 800-?m-diameter SoilChips were constructed by depositing a dispersed Oxisol A horizon suspension on a patterned glass. Dissolved organic matter from the original soil was added on the SoilChips to mimic SWI processes. The effects of ammonium fertilization (90 mg N kg?1 soil) on chemical composition of SWIs were evaluated via X-ray photoelectron spectroscopy. Over 21 days, ammonium addition increased OM coatings at SWIs and modified the OM chemical structure with more alcoholic- and carboxylic-C compared to the unfertilized control. Molecular modeling of OM composition at SWIs showed that N fertilization mainly facilitated the microbial production of glucans. We demonstrated that N availability modifies the specific OM molecular processing and its immobilization on SWIs, thereby providing a direct insight into biogeochemical transformation of OM at micro-scale. © 2019, The Author(s).
