Abstract:

The southwestern region of Rio Grande do Sul (RS) is characterized by large portions of sandy soils that have high environmental vulnerability, due to their low fertility and high susceptibility to erosion. Some of these soils have increased clay, suggesting allochtonous pedogenesis. In this case, the aims of this study were to determine evidence of allochtonous pedogenesis on sandstones Botucatu Formation in the southwestern region of the RS. A profile of Argissolo Vermelho and other of Neossolos Quartzarênico were analyzed, both formed on quartz sandstones of the Botucatu formation. Through morphological, physical, chemical and mineralogical analysis was possible to verify the process of allochthonous pedogenesis by higher clay content in the B horizon of the Argissolo profile and confirmed by the absence of clay forming minerals in the rock and in the presence of ilmenite in the pedogenetic horizons and its absence in the rock matrix. The environmental conditions suggest that the ilmenite originates from alteration of the surrounding volcanic rocks.

Abstract:

The structure, composition and cut and fill sequence of the Late Glacial and Holocene erosional landforms in the Kuitunka River basin on the right bank of the Selenga River were studied based on a detailed analysis and radiocarbon dating of the soil-sedimentary sequence in the Studenyi Klyuch 2 and Kovalev Pad’ sections. A correlation was carried out between seven sections in the intermittent stream valleys in the Kuitunka River basin. There are three episodes of the Late Glacial and Holocene cutting dated back to ~18–17, ~14.7–14.3, and 0.25–0 cal. kyr BP (ka BP). There are distinguished the periods of colluvial, colluvial-deluvial and aeolian-deluvial sediment deposition in the intermittent stream valleys (17.0–14.7 ka BP) and predominantly aeolian-deluvial loess-like sediment accumulation involving pedogenetic stages (14.30–0.25 ka BP). The climatic warming and humidification led to a decrease in sedimentation rate, prevalence of loessification processes in formation of loess-like deposits, and formation of organic–accumulative soil horizons of different thicknesses. The Late Glacial warming, comparable to the Bølling – Allerød Interstadial (14.3–12.9 ka BP) and the Holocene (11.7–0 ka BP), is characterized by a dynamic change in the stages of loess-like deposit accumulation and pedogenesis. The Younger Dryas cooling (12.9–11.7 ka BP) is associated with the activation of aeolian and cryogenic processes and a short phase of pedogenesis. It was revealed that the most frequent changes in sedimentary phases and soil formation occurred during the Late Glacial Interstadial and the Early (11.7–8.2 ka BP) Holocene. The Middle Holocene (8.2–4.2 ka BP) is characterized by a decrease in the rate of accumulation of intermittent-stream valley loess-like bottom deposits and a long-term (several ka) active pedogenetic process. The cross-sections of the Late Holocene (last 4.2 ka BP) draws and valley-bottom gullies exhibit the stages of pedogenesis (4.2–1.0 ka BP), activation of erosion–accumulation processes (1.00–0.25 ka), gullying, accelerated erosion, and accumulation (last 0.25 ka BP).

Abstract:

Soil bacteria play a fundamental role in pedogenesis. However, knowledge about both the impact of climate and slope aspects on microbial communities and the consequences of these items in pedogenesis is lacking. Therefore, soil-bacterial communities from four sites and two different aspects along the climate gradient of the Chilean Coastal Cordillera were investigated. Using a combination of microbiological and physicochemical methods, soils that developed in arid, semi-arid, mediterranean, and humid climates were analyzed. Proteobacteria, Acidobacteria, Chloroflexi, Verrucomicrobia, and Planctomycetes were found to increase in abundance from arid to humid climates, while Actinobacteria and Gemmatimonadetes decreased along the transect. Bacterial-community structure varied with climate and aspect and was influenced by pH, bulk density, plant-available phosphorus, clay, and total organic-matter content. Higher bacterial specialization was found in arid and humid climates and on the south-facing slope and was likely promoted by stable microclimatic conditions. The presence of specialists was associated with ecosystem-functional traits, which shifted from pioneers that accumulated organic matter in arid climates to organic decomposers in humid climates. These findings provide new perspectives on how climate and slope aspects influence the composition and functional capabilities of bacteria, with most of these capabilities being involved in pedogenetic processes.

Abstract:

Abstract Component part of the Carpathian-Danubian-Pontic space, the interfluve area between Prut and Dniester is subject to the regional process of climate evolution and change. In what regards the concept of human-influenced pedogenesis, the role of the biological factor is significantly reduced. As a consequence the direction and intensity of the elementary landscape and pedogenetic processes are determined by the relations between climate and the geomorphological factor. In the conditions of a relative stability of the geomorphological factor, the determining role is held by climate. To this is added soil vulnerability to the implications of climate changes, determined by the degree of soil physical degradation but also by a series of intrinsic and external (drainage) factors. This implies the idea of the control and management of the landscape and pedogenetic implications of climate changes by improving soil physical characteristics.

Abstract:

Belowground organisms play critical roles in maintaining multiple ecosystem processes, including plant productivity, decomposition, and nutrient cycling. Despite their importance, however, we have a limited understanding of how and why belowground biodiversity (bacteria, fungi, protists, and invertebrates) may change as soils develop over centuries to millennia (pedogenesis). Moreover, it is unclear whether belowground biodiversity changes during pedogenesis are similar to the patterns observed for aboveground plant diversity. Here we evaluated the roles of resource availability, nutrient stoichiometry, and soil abiotic factors in driving belowground biodiversity across 16 soil chronosequences (from centuries to millennia) spanning a wide range of globally distributed ecosystem types. Changes in belowground biodiversity during pedogenesis followed two main patterns. In lower-productivity ecosystems (i.e., drier and colder), increases in belowground biodiversity tracked increases in plant cover. In more productive ecosystems (i.e., wetter and warmer), increased acidification during pedogenesis was associated with declines in belowground biodiversity. Changes in the diversity of bacteria, fungi, protists, and invertebrates with pedogenesis were strongly and positively correlated worldwide, highlighting that belowground biodiversity shares similar ecological drivers as soils and ecosystems develop. In general, temporal changes in aboveground plant diversity and belowground biodiversity were not correlated, challenging the common perception that belowground biodiversity should follow similar patterns to those of plant diversity during ecosystem development. Taken together, our findings provide evidence that ecological patterns in belowground biodiversity are predictable across major globally distributed ecosystem types and suggest that shifts in plant cover and soil acidification during ecosystem development are associated with changes in belowground biodiversity over centuries to millennia.

Full text

Abstract:

AbstractThe simultaneous operation of regressive and progressive pedogenetic pathways raises the possibility that soil evolution may exhibit patterns far richer and more complex than increasing development over time. This possibility is explored via a numerical model incorporating the relative rates of progressive and regressive pedogenesis and feedbacks between these rates and the degree of soil development. This model may exhibit deterministic chaos and sensitive dependence on initial conditions with realistic parameter values. Variations in profile development in a region of the North Carolina Coastal Plain where soil-forming factors are relatively constant is consistent with deterministic chaos. Chaotic soil evolution suggests that soil development may reflect the interplay between progressive and regressive soil-forming processes in addition to—or instead of—the age of a surface or deposit. The former may produce a state of development which is unique to a particular time, sensitively dependent on the (unknown) initial conditions, and not simply related to age. Soils and their genetic signatures as indicators of relative ages and Quaternary environments may need to be reinterpreted in this light.

Abstract:

Nine soil profiles from a 52-km-long transect orthogonal to the coast of Southern James Bay range in age from 1000 to 3000 yr. The depth of carbonate leaching, mass of vermiculite clay formation, profile organic matter and amorphous material (Fe, Al and Si) accumulation were determined. Rates of these pedogenetic processes were calculated, and compared to rates in a cooler, drier area on the Hudson Bay Coast. The rates are about twice as rapid in the southern James Bay area as in the Hudson Bay Coastal zone. These differences in rates are explained on the basis of mean annual temperature and precipitation. Key words: Vermiculite, carbonate leaching, rates of pedogenesis

The analyses concerned with the characteristics of soil chemical, physical, and mineralogy of the rock fragment and sand, silt and clay fractions are to investigate the pedogenesis processes. Both soil profiles indicate the clayey texture, slightly neutral reaction, high cation exchange capacity, base saturation, and iron oxide. The mineralogical analyses of rock fragments and sand fractions indicate that besides carbonate minerals, silicate minerals were also found. The clay mineralogy showing the domination of kaolinite, gibbsite, and goethite, reflects that the soil is intensely weathered. Pedogenesis process showing the clay translocation, indicates that the weathering process has been occuring under the tropical influence.

Abstract:

Abstract The aim of the present study is to establish the biogeochemical characteristics of the primary soil formation, separately for natural conditions (protected areas) and urban environment (with incoming technogenic aerosols) for pedogenesis models when there is no parent rock (“upward soil growth”). This makes it possible to assess the contribution of the still poorly studied pedogenesis factors that can form the specific geochemical features of the material composition of soils non-inherited from the parent rock, and without the involvement of biogenic bottom-up migration of elements. We have studied two contrasting regions to perform a comparative analysis of pedogenesis conditions. We have compared embryonic soils on megalithic gabbro-diabase blocks in a 17th century defence wall located on the territory of a natural reserve, 1 km away from the Black Sea coast (ecologically clean area) and a 45-year solid bitumen cover between a thermal power plant and a busy railway (an industrial zone in the central part of the city). In the natural reserve, the average dust deposition rate was 0.82 um yr1 (0.082 mm/100 yr) due to stardust, atmospheric aerosols and biogenic processes of pedogenesis. The mineral part of soils, which had formed on the solid bitumen in 45 years in the city’s industrial zone, differs from the soil developed in 320-350 years without the involvement of the parent rock in the protected area by higher content of V (9 times) and Cr (2 times), as well as CaO, SiO2 and Pb. In the industrial zone of the city, emission dust mostly contributes to the accumulation of V, Cr and Cu in comparison with the pedogenesis conditions in the ecologically clean area, where the rate of solid-phase soil matter accumulation is twice lower due to background aerosols and biogenic factors.

The underlying rocks, a tholeiitic basalt in Nova Scotia and a basic greenstone schist at Kamloops, were apparently transformed to predominantly smectitic saprolites in pre-Holocene times. During the Wisconsinan glacial stage the sola and a significant portion of the saprolites were removed. Holocene pedogenesis has produced new sola on the saprolites. In Nova Scotia, the solum may have some locally derived till or colluvium component. Key words: Mafic pedogenesis, Paleosols, soil mineralogy

Abstract:

Variability of soil types in the Quaternary geological formations on the islands presents different soil morphological characteristics. The process of geomorphogenesis and geology determines the characteristics of soil morphology. This study aims to determine the characteristics of soil morphology, pedogenesis process, soil development based on landforms in Quaternary geological formations in North Maluku Islands region. Six soil profiles were observed, which were determined based on geographical location. Descriptive research methods based on USDA standards were used as the basis for determining soil morphological characteristics. The results showed that the pedogenesis process on Quaternary volcanic landforms were caused by a period of volcanic eruptions characterized by thick soils (>100 cm), fairly steep slopes (15 - 25%), no rock outcrops, and an eluviation-illuviation process on the soil profile. While the pedogenesis process on alluvial landforms tends to produce in-situ rock weathering characterized by slow horizon formation and produces a relatively shallow soil solum (<100 cm). The data obtained provide information on soil resources and the research results can also be used as a formulation in conservation efforts on the islands.

AbstractSustainable forest management requires understanding of ecosystem phosphorus (P) cycling. Lang et al. (2017) [Biogeochemistry,https://doi.org/10.1007/s10533-017-0375-0] introduced the concept of P-acquiring vs. P-recycling nutrition strategies for European beech (Fagus sylvatica L.) forests on silicate parent material, and demonstrated a change from P-acquiring to P-recycling nutrition from P-rich to P-poor sites. The present study extends this silicate rock-based assessment to forest sites with soils formed from carbonate bedrock. For all sites, it presents a large set of general soil and bedrock chemistry data. It thoroughly describes the soil P status and generates a comprehensive concept on forest ecosystem P nutrition covering the majority of Central European forest soils. For this purpose, an Ecosystem P Nutrition Index (ENIP) was developed, which enabled the comparison of forest P nutrition strategies at the carbonate sites in our study among each other and also with those of the silicate sites investigated by Lang et al. (2017). The P status of forest soils on carbonate substrates was characterized by low soil P stocks and a large fraction of organic Ca-bound P (probably largely Ca phytate) during early stages of pedogenesis. Soil P stocks, particularly those in the mineral soil and of inorganic P forms, including Al- and Fe-bound P, became more abundant with progressing pedogenesis and accumulation of carbonate rock dissolution residue. Phosphorus-rich impure, silicate-enriched carbonate bedrock promoted the accumulation of dissolution residue and supported larger soil P stocks, mainly bound to Fe and Al minerals. In carbonate-derived soils, only low P amounts were bioavailable during early stages of pedogenesis, and, similar to P-poor silicate sites, P nutrition of beech forests depended on tight (re)cycling of P bound in forest floor soil organic matter (SOM). In contrast to P-poor silicate sites, where the ecosystem P nutrition strategy is direct biotic recycling of SOM-bound organic P, recycling during early stages of pedogenesis on carbonate substrates also involves the dissolution of stable Ca-Porg precipitates formed from phosphate released during SOM decomposition. In contrast to silicate sites, progressing pedogenesis and accumulation of P-enriched carbonate bedrock dissolution residue at the carbonate sites promote again P-acquiring mechanisms for ecosystem P nutrition.

Abstract:

The Estimation of the relative intensity of different cold periods occurring during the Late Quaternary is a difficult task, particularly in non-glaciated mountain landscapes and where high- to medium-resolution archives for proxy data are lacking. In this paper, we study a Holocene polycyclic soil sequence in the central Alps (Val Cavargna, Northern Italy) to estimate climatic parameters (specifically Temperature) changes in non-glaciated, high altitude environments. We investigate this key site through palaeopedological and micromorphological analyses in order to understand phases of soil development and detect hidden evidence of cold conditions during its formation. Three phases of pedogenesis can be recognized and attributed in time to different periods during the Holocene. Pedogenetic phases were separated by two truncation and deposition episodes related to the reactivation of slope processes under cold conditions at the onset of the Neoglacial and the Iron Age Cold Epoch, respectively. Micromorphological evidence of frost action in the soil can instead relate to pedogenetic processes acting in the Little Ice Age. The different expression of these three cold periods corresponds to changes in climatic conditions, pointing to the Little Ice Age as a cooler/drier period in comparison to the preceding ones.

Abstract:

AbstractDiscovery in 1980 of Camp 18 of the 1930 Bagnold expedition in northwestern Sudan has resulted in an exceptionally long record of barchan movement from which an average rate of 7.5 m/yr has been calculated. Measurements of the rate of dune advance since 1980 have not varied significantly, indicating a state of quasiequilibrium exists. The dune field is moving over an undulating sand sheet exhibiting various stages of Holocene pedogenesis and containing Neolithic sites. The sand sheet overlies Pleistocene alluvium with stronger stages of pedogenesis. All of these deposits may be a significant source of dune sand. Wind-blown grass fragments trapped by advancing slipfaces mark former slipface positions and indicate late Holocene rainfall events, which can be radiocarbon dated. Parabolic forms (revealed by SPOT images) at the windward ends of the dune fields are transitional to barchans, suggesting sand accumulation in vegetation germinated during a Holocene wet period. In addition, sand streaks from sand-sheet undulations suggest that active eolian erosion of sand sheets contributes to the sand supply of dune fields. Pedogenesis during pluvial periods contributes to silt and clay fractions of bimodal sand sheet sediments. From wind streaks on LANDSAT images and an estimated average rate of dune advance, positions of dune fields during past hyperarid periods can be estimated.

Abstract:

Increasing the pressure of techno-anthropogenic factors on arable chernozems, in conditions of intensification of the degree of continentality of the soil climate induced by climate change, against the background of unidirectional reduction of the role of the biological factor in the anthropo-natural chernozem pedogenesis, involved a newphase in its evolution in which the decisive role belongs to physical degradation. It is distinguished by significant changes in typogenetic chernozeomic processes: a) formation and accumulation of humus; b) aggregation-structuring of the soil mass. Within the complex process of decomposition-transformation of fresh organic matter, the weight of the humus formation and accumulation process is reduced and the weight of the mineralization process is increased. Biocoagulation processes of aggregation-structuring of the soil mass is significantly reduced. Instead, it increases the share of thermocompression and physical-mechanical processes in the evolution of the aggregate system of arable chernozems. This leads to the disruption of the functionality of the pedofunctional system [humic system] ↔ [aggregatesystem] manifested in the reduction of the meaning and intensity of the reproductive processes of chernozemous pedogenesis and the natural fertility of arable chernozems. In the current phase of chernoziomic pedogenesis, anthropo-natural agrogenesis manifests itself in the attenuation of differences at the subtype taxonomic level.

Abstract:

Abstract This article examines the rise of urban soils as a topic of scientific inquiry and ecological engineering in France, and questions how new framings of soil as a material that can be designed reconfigure relationships between urban life and soils in a context of fast-growing cities. As a counterpoint to the current situation, the article first examines how the hard-surfacing of Paris, in the nineteenth century, sought to background the vital qualities of soils in urban areas, making their absence seem perfectly stable and natural. It then shows how the new urban soil science moved away from classical descriptive approaches to soils, and set out to fabricate soils as a research experiment on anthropo-pedogenesis. In the French context, urban soil scientists soon formed new bonds with the worlds of urbanism, administration, and waste management, reframing their approach as a technical response to issues brought by sprawling cities, backgrounding soils again under a trope centered on the management of soil services. These stories allow to critically inhabit soil scientists’ claim that humans participate in pedogenesis by examining the specific conditions in which modern modes of being in the world and urban soils become entangled or disentangled in modern metropolis.

Abstract:

Abstract The chernozems evolution of the Carpatho-Danubian-Pontic space clearly shows two consecutive phases: climatogenic and anthropo-climatogenic. The latter is characterized by increasing agrogenic impact on soil climate. The soil cover of Carpathian-Danubian-Pontic space is the hierarchical functional system long-time product. Pedogenetic factors → pedogenetic regimes → pedogenetic processes → soil (soil cover). During Pleistocene, the chernozem pathogenesis in the region resumed 13 times, each time starting from the carbonic chernozem phase. Zonal climatic cyclicality has led to the differentiation of chernozem subtypes, determined by the zonal differentiation of pedogenic regimes and typogenetic elemental processes. The current stage of chernozem cleavage in the region began 10-12 thousand years ago. The evolution of soils in the soil was determined by the climate cyclicality and the increase of anthropogenic imputations and involves the succession over time of several phases: - Cryogenic with poorly developed soil by A (AO) - C Order; - Early dynamic halocene with developed zonal soil formation; - Late halocene with climatic evolution of the profile; - Natural-anthropogenic. During the last one, four eras were accelerated: natural-anthropo-turbian, naturalanthropic modification, natural-anthropic restructuring and natural-anthropic stagnation. Increasing the anthropogenic impulses led to the modification of the climatic → soil relations in the sense of increasing the degree of continentalisation of the soil climate materialized in the aridization of the soil cover, the change of the sense and intensity of the typogenic processes and the induction of some nontypical elementary processes of the chernozemic pedogenesis.

Abstract:

Engineering and geographic substantiation of the anti-erosion organization of agricultural landscapes requires not only differentiated estimations of erosion losses, but also commensurate (in terms of space–time scales) estimations of the soil loss tolerance. The main approaches for determining the participation of estimations of soil formation in the substantiation of erosion tolerance have been defined. This study is aimed at justifying the methods of incorporating the results of pedogenesis modeling into computational methods for organizing agricultural landscapes. This paper presents the results of a study of the process of formation of the humus horizon and the accumulation of organic carbon in soils, based on soils from archaeological sites in the Crimean Peninsula over a period from 25 to 2000 years ago, with differences in climate and parent rock, in a region with a thousand-year history of human activity. The patterns of variation in the thickness of the humus horizons over time and the accumulation of carbon were determined, and estimates for the rate of the pedogenesis were obtained. In connection with the slowing of the rate of pedogenesis over time, the chronofunction of the change in the thickness of soils (of both exponential and logistic types) may be applied and, on this basis, it is possible to calculate the rates of the formation of the humus horizon depending on the morphological status of the soils. During re-naturation of highly degraded soils, maximum renewal rates may take place only with a very high input of organic matter, which is crucial to take into account in the development and implementation of programs for the rehabilitation of degraded lands. Under the conditions of slope agriculture, the rationale for T-values should be linked to many factors of the input and consumption of organic carbon, which provides a logical mathematical model of the formation of soil quality. For soil quality management on agricultural lands, a formula for calculating T-values, using an equation where the rate of pedogenesis is associated with a variety of changes in soil organic carbon, is proposed in this article.

Abstract:

Abstract The high mountainous southeastern part of Russian Altai is characterized by complicated sedimentation history. As a result of tectonic movements, Paleogene, Neogene, and even more old Carboniferous and Jurassic organicrich deposits had been partly uplifted and exhumed on the ridge’s slopes, where during the Pleistocene, they were affected by various exogenous processes including glaciation, glacio-fluvial erosion, winnowing activity of ice-dammed lakes, sliding during lake-draining events, followed by further intensive Holocene erosion, pedogenesis, and permafrost formation/degradation. Remobilized ancient organic matter had been involved into geomorphic and pedogenesis processes and affected the results of radiocarbon dating. Numerous radiocarbon ages obtained revealed several typical problems in interpretation of dating results, which was confirmed by multidisciplinary investigations of associated sediments in a wider regional context. This article presents a discussion on obtained apparent radiocarbon dates of organic material from ten sections of the SE Altai. In addition to radiocarbon analysis, in each case multidisciplinary study was carried out in order to properly interpret obtained dates, as well as to explain the inability of directly using apparent 14C ages as a geochronological basis for paleogeographical reconstruction. The analysis presented is of vital importance for establishing the chronology of formation of large ice-dammed lakes and their cataclysmic draining; revealing chronology and paleoenvironmental conditions of pedogenesis in the highlands of the SE Altai; and estimating the range and magnitude of the tectonically driven topography rebuilding in the post-Neogene time.

Abstract:

The first data on the age of secondary carbonate pendants in the soils of the Upper Angara region are given. Based on the study of the conditions of occurrence, morphology, material and isotopic composition, three groups of carbonate kutans were identified. The direct 14C AMS dating of the coating’s microlayers allowed to determineintervals of their formation. Pendants of the first group were formed in the middle Holocene (3.6-3.3 kyr BP). The formation of coatings of the second and third groups took place in the second half of MIS-3 (24.1-23.3 and ~34-35 kyr BP, respectively). The paleoecological conditions reconstructed for the identified stages of the formation of carbonate pendants satisfactorily correlate with the climate changes in the region and the northern hemisphere as a whole, reflecting the influence of temperature and moisture fluctuations on the dynamics of soil formation processes. Comparison of the age of carbonate accumulations with the age of modern and buried soils shows that pedogenic carbonatecoatings in the soils of the Upper Angara region are a relict feature of previous stages of pedogenesis (MIS-3) and the first stages of modern soil formation, which began, apparently, in the middle Holocene. The close ratios of the composition of stable carbon and oxygen isotopes in mid-Holocene and Late Kargin (MIS-3) coatings suggest that there is a similarity of pedogenesis conditions in these time intervals, primarily due to the relatively low temperature of pedogenesis and the duration of the seasonally frozen of soils.

Abstract:

Abstract In studies of the magnetic properties of soils, the frequency-dependent magnetic susceptibility percentage (χFD%) is often used for the identification of ultrafine magnetically superparamagnetic/stable single-domain (SP/SSD) particles. This parameter is commonly used as an indicator for increased pedogenesis. In strongly magnetic soils, the SP/SSD magnetic signal (mostly bio-pedogenic) may be masked by lithological signals; making pedogenesis hard to detect. In this study, we compare results for the detection of ultrafine SP/SSD magnetic particles in andic soils using two instruments: a Bartington MS2B dual-frequency meter and an AGICO Kappabridge MFK1-FA. In particular, the study focuses on the effect of pedogenesis by investigating the relationship between specific soil magnetic and chemical properties (soil organic carbon and pHH2O). The values of χFD% obtained with the MS2B varied from 2.4 to 5.9 per cent, and mass-specific magnetic susceptibility (χLF) from 283 to 1688 × 10−8 m3 kg−1, while values of χFD% and χLF obtained with the MFK1-FA varied from 2.7 to 8.2 per cent and from 299 to 1859 × 10−8 m3 kg−1, respectively. Our results suggest that the detection of the SP/SSD magnetic fraction can be accomplished by comparing relative trends of χFD% along the soil profile. Moreover, the discrimination between bio-pedogenic and lithogenic magnetic contributions in the SP/SSD fraction is possible by comparing the χFD% and χLF data determined in the fine earth (&lt;2 mm) and the coarse fraction (4–10 mm) samples down the soil profile.
