Abstract (sommario):

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 (sommario):

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 (sommario):

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 (sommario):

This work examines the use of pedo-properties to identify dune soil system responses to environmental change on the Sefton coast, based on the development of conceptual pedogenic models. Previous environmental change and shoreline dynamics are determined through O.S. maps and aerial photographs, while present day processes are investigated through a dune-toe photographic survey and seasonal monitoring by fixed point photography. Topsoil (0-5 cm) physico-chemical characteristics are presented in a series of baseline GIS maps, displaying spatial pedo-property variation across the dune landscape. Combined with vegetation data, topsoil analysis identifies 10 distinct pedo-environments. Physico-chemical characteristics of associated National Soil Resources Institute (NSRI) soil profile classifications and an exposed stratigraphic section are presented graphically in a proposed sequence of development. Topsoil and soil profile samples are analysed for soil pH, soil organic matter (SOM) content, particle size, geochemical composition and mineral magnetism. Significant differences (p <0.05) are apparent for the suite of topsoil characteristics collated, indicating discrete dune environments are influenced by specific soil properties. Distinct down-profile variations in soil characteristics are also apparent between dune environments, highlighting pedological dynamism. Multivariate Factor analysis groups bare sand and mobile dune communities into ‘frontal dunes’ and fixed dune community, pasture, scrub, deciduous woodland and coniferous plantations into ‘hind dunes’, separating these topsoil environments from heath and slack communities. Factor analysis also identifies linkages between pedo-characteristics within soil profile horizons, suggesting pedogenesis on the Sefton dunes initiates as raw sand, progressing to sand-pararendzinas through leaching of nutrients. Desalinization and decalcification processes lead to brown earth development, followed by increased acidicification, subsequently, resulting in micro-podzol formation. Groundwater gley soils are associated with dune slacks, where drainage is inhibited and anaerobic conditions prevail. Analysis of buried soils suggests such pedo-environment formations are cyclic, responding to phases of shoreline regression/transgression, dune activity and stabilization. Conceptual models are designed to graphically demonstrate pedogenesis under both erosion and deposition regimes on the Sefton coast. Regression equations and correlation coefficients between pedo-properties and distance from mean high water are used as a proxy for soil age, which represent lateral soil maturity from the unstable frontal dunes to the stable hind dunes inland. The models simulate formation and process of the full array of soil properties, accounting for geomorphological impacts and anthropogenic influences. This has great implications for dune managers by raising awareness of pedogenesis as an integral part of nature and associated habitats, which could be incorporated in future shoreline management plans (SMPs).

The last eustatic events, coupled with the intense amount of sediments in the coastal plain gave rise to a set of geo-environmental units, such as the marine fluvial plains, home to the apicuns. This subunit is an area for the expansion of mangroves in periods of increase in the average sea level. Moreover, it is a environment related with the reproduction, protection and development of mangrove fauna as well as assists in the socio-economic and cultural aspects of local people. However, despite its important ecological function, there are few research involving the genesis of its soils. In this sense, this study aimed to contribute to the understanding of the dynamics of this coastal system under the pedological view. Apicuns located southeast and northwest of CearÃ were selected and were held morphological, physical, chemical, geochemical, morphoscopic and micromorphological analyzes. The results showed that the fluctuation of the water table allowed the intense iron oxide precipitation and the incipient structuring of the soil. The contribuition of sandy material with nature thin to very thin and well selected grain from dunes has been verified. Furthermore, it was found that the northwest apicum have a lower degree of development as compared with the other soils, since the morphology and mineralogy support this fact. Also, there is differentiation in iron content between the two estuaries and disfavoring in the genesis of pyrites. In this case, the presence of pyrite in conditions not conducive to their formation indicates that apicum has its genesis correlated with areas of mangroves and should be considered, before the law, member of the mangrove ecosystem.
Os Ãltimos eventos eustÃticos, aliado ao intenso aporte de sedimentos na planÃcie costeira deram origem a um conjunto de unidades geoambientais, como por exemplo, as planÃcies fluviomarinhas, que abrigam os apicuns. Essa subunidade Ã uma Ãrea para a expansÃo do manguezal em perÃodos de aumento do nÃvel mÃdio do mar. AlÃm disso, Ã um ambiente relacionado com a reproduÃÃo, proteÃÃo e desenvolvimento da fauna do manguezal, bem como auxilia nos aspectos sÃcioeconÃmico- cultural da populaÃÃo local. No entanto, apesar da sua importante funÃÃo ecolÃgica, poucas sÃo as pesquisas que envolvam a gÃnese de seus solos. Neste sentido, esse estudo teve por finalidade contribuir para o entendimento da dinÃmica deste sistema costeiro sob a visÃo pedolÃgica. Para tanto, foram selecionados apicuns situados a sudeste e a noroeste do Estado do CearÃ, onde foram realizadas anÃlises morfolÃgicas, fÃsicas, quÃmicas, geoquÃmicas, morfoscÃpicas e micromorfolÃgicas. Os resultados encontrados mostraram que a flutuaÃÃo do lenÃol freÃtico permitiu a intensa formaÃÃo de mosquedos e a incipiente estruturaÃÃo do solo. Foi verificada a contribuiÃÃo de material arenoso de natureza fina a muito fina e de grÃos bem selecionados proveniente de dunas. AlÃm disso, verificou-se que os solos do apicum a noroeste possuem menor grau de desenvolvimento, em comparaÃÃo com os demais solos estudados, visto que a mineralogia e a micromorfologia suportam este fato. AlÃm disso, hÃ diferenciaÃÃo nos teores de ferro entre os dois estuÃrios e desfavorecimento na gÃnese de piritas. Neste caso, a presenÃa de pirita em condiÃÃes nÃo propÃcias Ã sua formaÃÃo indica que o apicum possui sua gÃnese correlacionada com os domÃnios de mangues, devendo ser considerado, diante das leis, integrante do ecossistema manguezal.

Abstract (sommario):

Three studies were completed to investigate the influence of mineral assemblage on soil organic carbon (SOC) cycling and pedogenesis in forest soils. Two studies utilized a lithosequence of four parent materials (rhyolite, granite, basalt, limestone/volcanic cinders) under Pinus ponderosa, to explicitly quantify the contribution of parent material mineral assemblage to the character of the resulting soil. The first study explored variation in pedogenesis and elemental mass loss as a product of parent material through a combination of quantitative X-ray diffraction and elemental mass balance. Results indicated significant differences in degree of soil development, profile characteristics, and mass flux according to parent material.The second study utilized the same lithosequence of soils, but focused on organic C cycling. This study explored variation in SOC content among soils of differing mineralogy and correlations among soil physiochemical variables, SOC content, soil microbial community composition and respiration rates. Metal-humus complex and Fe-oxyhydroxide content emerged as important predictors of SOC dynamics across all parent materials, showing significant correlation with both SOC content and bacterial community composition. Results indicated that within a specific ecosystem, SOC dynamics and microbial community vary predictably with soil physicochemical variables directly related to mineralogical differences among soil parent materials.The third study focused specifically on the influence of goethite and gibbsite on dissolved organic matter characteristics and microbial communities which utilize DOM as a growth substrate. Iron and aluminum oxides were selected for this study due to their wide spread occurrence in soils and their abundance of reactive surface area, qualities which enable them to have a significant effect on SOC transported through forest soils. Results indicated that exposure to goethite and gibbsite surfaces induces significant differences in DOM quality, including changes in thermal properties, molecular structure, and concentrations of P and N. Investigation of the decomposer communities indicated that exposure to goethite and gibbsite surfaces caused significant differences in microbial community structure.These investigations emphasize the important role of mineral assemblage in shaping soil characteristics and regulating the cycling of C in soils, from the molecular scale to the pedon scale.

The soils formed on limestone rocks in semiarid climate of the Apodi Plateau show distinct characteristics of the rest of the state of CearÃ. In Apodi Plateau soils factors of soil formation are homogeneous, what suggests that this geomorphological formation sat up so the exposure time of the parent material of different soils is the same, the relief is homogeneous, the vegetation is caatinga across the Plateau and the distance between different profiles is small to suggest a possible change in climate, so it is supposed that the strong variations in soil classes are closely related to lithological variations. The Apodi Plateau in its Cearense portion covers four municipalities: QuixerÃ, Tabuleiro do Norte, Alto Santo and Limoeiro do Norte, the latter being the search location. The lithological constitution is predominantly limestone with different facies. It was established a transect with approximately 300 m, where observations were made by auger evaluations that allowed to select the locations of the five profiles. Morphological descriptions of the profiles were made and samples collection for physical analysis: granulometry, particle and soil density,determination of the gravel fraction, clay dispersed in water, quantity of nodules, and these were divided into five classes C1, C2, C3, C4 and C5, with diameter from 0.053 to 0.25 mm, 0.25 to 2 mm, 2 to 4.76 mm, 4.76 to 7.9 mm, 7.9 to 19.1 mm, respectively . Chemical analysis were to determine cation exchange capacity - CEC, phosphorus, total organic carbon - TOC, pH in water and KCl, selective dissolution of Fe in Citrate Dithionite Bicarbonate - DCB, Ammonium Oxalate and Sulfuric acid to determine the levels of total Fe, Al and Si in the clay fraction, and determine the molecular indices Ki and Kr. Three profiles were classified as Argissolos and two as Cambissolos. All the profiles showed significative quantity of nodules, which decreased in diameter yet increasing mechanical resistance as they neared the surface, where it had an aspect similar to "chumbo de caÃa." The data showed variations within and between profiles, such as the amount of gravel, which in one of the profiles of Cambissolos fell in the order of 780 g.kg-1 for 30 g.kg-1, a fact corroborated by the levels of Titanium, which indicate that such variations are due to different lithogenic origins. This allows us to conclude that among the factors of soil formation, parent material prints its characteristics as reflected in the different soil classes within a few meters between soil profiles and even a few inches of soil horizons.
Os solos formados sobre rochas calcÃrias no clima semiÃrido da Chapada do Apodi apresentam caracterÃsticas distintas da grande maioria do restante do estado do CearÃ. Nos solos da Chapada, os fatores de formaÃÃo sÃo homogÃneos, ou seja, esta formaÃÃo geomorfolÃgica soergueu e o tempo de exposiÃÃo do material de origem de diferentes solos Ã o mesmo, o relevo Ã plano, a vegetaÃÃo Ã caatinga em toda a extensÃo e a distÃncia entre perfis diferentes Ã pequena para sugerir uma possÃvel variaÃÃo no clima. Desta maneira, suspeita-se que as fortes variaÃÃes nas classes de solos estÃo intimamente ligadas a variaÃÃes litolÃgicas. A Chapada do Apodi na sua porÃÃo cearense abrange quatro municÃpios, QuixerÃ, Tabuleiro do Norte, Alto Santo e Limoeiro do Norte, sendo neste Ãltimo o local da pesquisa. A constituiÃÃo litolÃgica Ã predominantemente carbonÃtica, com diferentes fÃcies. No local foi definido um transecto de aproximadamente 300 m, onde foram feitas observaÃÃes por tradagens, que permitiram selecionar os locais dos cinco perfis. Foram feitas as descriÃÃes morfolÃgicas dos perfis e coletas das amostras para anÃlises fÃsicas: granulomÃtrica, densidade das partÃculas e do solo, determinaÃÃo da fraÃÃo cascalho, argila dispersa em Ãgua quantidade de nÃdulos, sendo que estes foram divididos em cinco classes, C1, C2, C3, C4 e C5, com os seguintes diÃmetros 0,053 a 0,25 mm, 0,25 a 2 mm, 2 a 4,76 mm, 4,76 a 7,9 mm, 7,9 a 19,1 mm, respectivamente. As anÃlises quÃmicas foram para determinar capacidade de troca de cÃtions - CTC, fÃsforo, carbono orgÃnico total â COT, pH em Ãgua e KCl, dissoluÃÃes seletivas do Fe em Ditionito Citrato Bicarbonato de SÃdio â DCB, Oxalato de AmÃnio e Ataque SulfÃrico para determinaÃÃo dos teores de totais de Fe, Al e Si na fraÃÃo argila, alÃm de determinar os Ãndices moleculares Ki e Kr. Foram encontrados trÃs perfis de Argissolos e dois Cambissolos. Em todos estes perfis foi encontrada significativa quantidade de nÃdulos, que diminuÃam de diÃmetro, porÃm aumentavam sua resistÃncia mecÃnica Ã medida que se aproximavam da superfÃcie do solo, onde tinha um aspecto semelhante a âchumbo de caÃaâ. Os dados obtidos mostraram variaÃÃes intra e inter perfis, tais como o teor de cascalho, que em um dos perfis de Cambissolos caiu da ordem de 780 g.kg-1, para 30 g.kg-1 fato corroborado pelos teores de TitÃnio, que sugerem que tais variaÃÃes se devam a diferentes origens litogÃnicas. Isso nos permite concluir que dentre os fatores de formaÃÃo destes solos, o material de origem imprime suas caracterÃsticas de forma que isso se reflete nas diferentes classes de solos distanciados de poucos metros entre perfis e mesmo em poucos centÃmetros entre horizontes de solos.

The Coastal Tablelands are a geomorphological unit associated with sediments of Barreiras Formation and feature great interest to farm. However, some soils of this region have subsurface horizons with cohesive character, which can cause physical impediments to the development of the root system and the dynamics of water. The genesis of the cohesive character has not yet been fully elucidated, but it is known that occurs naturally. However, some studies have linked the genesis of these horizons to several factors such as particle size of the soil, clay translocation processes and the action of organic and inorganic cementing agents. Thus, this study was conducted in order to obtain greater insight into the characteristics and the genesis of soils with this character. Therefore, soils were studied presenting horizons with cohesive character, seeking to identify and characterize processes that govern the genesis horizons with cohesive character in soils of Coastal Tablelands of CearÃ. The study was conducted in two areas of the Coastal Plains of the state of CearÃ (Pacajus and Trairi), where soils are arranged in topossequence and present cohesive character. The samples were subjected to physical fractionation of the sand fraction and morphoscopic analysis. Sequential extraction was carried out on Si surface and subsurface horizons, as well as chemical fractionation of humic substances. The results show that the two areas of study have different processes associated with the genesis of cohesive. In Pacajus soils showed moderate degree of selection, however the high concentration of clay subsurface influences the density of these soils. The cohesive soils of Trairi have a poor degree of selection, which facilitates the adjustment of these particles and the action of low crystalline compounds as cementing agent.
Os Tabuleiros Costeiros constituem uma unidade geomorfolÃgica associada aos sedimentos da FormaÃÃo Barreiras e apresentam grande interesse para exploraÃÃo agrÃcola. No entanto, alguns solos dessa regiÃo apresentam horizontes subsuperficiais com carÃter coeso, os quais podem causar impedimentos fÃsicos ao desenvolvimento do sistema radicular e Ã dinÃmica da Ãgua. A gÃnese do carÃter coeso ainda nÃo foi completamente esclarecida, apenas sabe-se que ocorre de forma natural. No entanto, alguns trabalhos tÃm associado a gÃnese desses horizontes a diversos fatores como a granulometria dos solos, processos de translocaÃÃo de argila e a aÃÃo de agentes cimentantes orgÃnicos e inorgÃnicos. Dessa forma, este trabalho foi desenvolvido com o intuito de obter maior conhecimento sobre as caracterÃsticas e a gÃnese de solos que apresentam esse carÃter. Para tanto, foram estudados solos que apresentem horizontes com carÃter coeso, procurando-se identificar e caracterizar processos que regem a gÃnese de horizontes com carÃter coeso nos solos dos Tabuleiros Costeiros do CearÃ. O estudo foi realizado em duas Ãreas dos Tabuleiros Costeiros do estado do CearÃ (Pacajus e Trairi), nas quais os solos estÃo dispostos em topossequÃncia e apresentam carÃter coeso. As amostras foram submetidas a fracionamento fÃsico da fraÃÃo areia e anÃlise morfoscÃpica. A extraÃÃo sequencial de Si foi realizada em horizontes de superfÃcie e subsuperfÃcie, assim como o fracionamento quÃmico das substÃncias hÃmicas. Os resultados apontam que, as duas Ãreas de estudos apresentam diferentes processos associados Ã gÃnese do coeso. Em Pacajus os solos apresentaram moderado grau de seleÃÃo, no entanto a elevada concentraÃÃo de argila em subsuperfÃcie influencia o adensamento desses solos. Os solos coesos de Trairi apresentam um pobre grau de seleÃÃo, o que facilita o ajuste dessas partÃculas e a aÃÃo de compostos de baixa cristalinidade como agente cimentante. Os fracionamentos horizontes com carÃter coeso e sem carÃter coeso, entretanto os compostos de baixa cristalinidade apresentam Al com teores mais altos e Si em menor proporÃÃo.

Abstract (sommario):

This study measured the effects of spoil type and amendments on Appalachian mine soil properties over time. The Controlled Overburden Placement Experiment was installed in 1982 in two parts, the Rock Mix (RM) Experiment compares mixes of sandstone (SS) and siltstone (SiS) spoils while the Surface Amendment (SA) Experiment compares a fertilized control (CON), sawdust (SD at 112 Mg ha-1), topsoil (TSâ 15 cm), and biosolids (BS) at 22, 56, 112 & 224 Mg ha-1. Both experiments were sampled in 2008 and compared with historical data. After 26 years, all RM treatments had higher silt+clay and decreased sand. Mine soil pH and electrical conductance (EC) were lower in high SS spoils and overall pH was lower and EC higher in surface layers. Fe-oxides increased over time and adversely affected extractable P. Exchangeable cations and total N increased in all treatments. Annual C-sequestration rates were 0.51 Mg ha-1 for 1:1 SS:SiS and 0.32 Mg ha-1 for SiS. In the SA experiment, extractable P and exchangeable cations increased over time in organically amended plots. The CON and TS sequestered C at 0.54 Mg ha-1 and 0.87 Mg ha-1 annually while higher BS and SD treatments lost C, but mobilized significant C into their subsoils. In the SA, an apparent C retention maximum of 30-35 Mg ha-1 was noted. Overall, rock type and amendment effects were still evident after 26 years and the long-term benefits of organic amendments were reflected in sustained higher C, exchangeable cations, total N and P levels.

Abstract (sommario):

The specificity of zonal pedogenesis factors and their influence on the horizon thickness in the soil profile contributes to the formation of specific characters for each horizon. A clear example can be observed in the interaction between pedogenesis and hydrology, where the illuvial and spontaneous processes move soil-clay minerals, oxides, soil carbon, carbonates and other compounds into the soil profile. Such reciprocal links allow the application of the statistical analysis to assess the variability of the horizons thickness and the prognosis of their spatial spread in relation to the factors that determine the formation of the horizon thickness.

Abstract (sommario):

In our time, a very urgent problem is the cessation of negative impacts on the environment and the return to the practical use of the territories of devastated lands. In this regard, it is important to find out the basic laws of primary soil formation in the area of these man-made neoplasms. The initial soil formation conditions were analyzed on 19 experimental sites which represent the main varieties of devastated land in the Kryvyi Rih Iron Mining and Metallurgical District (Central Ukraine): (i) waste rock dumps of old iron mines (old name “Forges”), (ii) tailing storage facility of underground iron mines, (iii) waste rock dumps of the Iron Ore Mining and Dressing Plant, (iv) waste rock dumps of the Granite Quarry Plant. It was established that on the devastated lands in Kryvyi Rih District, the initial soil formation occurs in very difficult conditions. Therefore, over 25- 100 years only very primitive soils were formed. The following features are inherent to them: (1) primitive soil profile (thickness 10-100 mm), (2) low levels of soil organic substance content (9.5-11.5 %), (3) alkaline indicators of the soil solution (pHH2O – 8.08-8.92, pHKCl – 7.42-8.23), (4) low levels of cation exchange capacity (6.34-8.47 mMol /100 g). By results of correlation calculations, among the factors of soil formation time (duration of soil formation) and input of plant ash elements’ fall are characterized by the maximum number of statistically significant correlation coefficients and their numerical values. In terms of chemical composition of the technosol, the values of organic matter content and exchangeable acidity (pHKCl) were the most predictable soil formation factors. Generally physical / chemical characteristics of geological rocks (as parent material) and time were the two most important factors in determining the initial pedogenesis on devastated lands in the Kryvyi Rih Iron Mining & Metallurgical District (Ukraine).

Abstract (sommario):

The multiple schema for the classification of soils rely on differing criteria but the major soil science systems, including the United States Department of Agriculture (USDA) and the international harmonized World Reference Base for Soil Resources soil classification systems, are primarily based on inferred pedogenesis. Largely these classifications are compiled from individual observations of soil characteristics within soil profiles, and the vast majority of this pedologic information is contained in nonquantitative text descriptions. We present initial text mining analyses of parsed text in the digitally available USDA soil taxonomy documentation and the Soil Survey Geographic database. Previous research has shown that latent information structure can be extracted from scientific literature using Natural Language Processing techniques, and we show that this latent information can be used to expedite query performance by using syntactic elements and part-of-speech tags as indices. Technical vocabulary often poses a text mining challenge due to the rarity of its diction in the broader context. We introduce an extension to the common English vocabulary that allows for nearly-complete indexing of USDA Soil Series Descriptions.
