Abstract:
Abstract. Equatorial podzols are soils characterized by thick sandy horizons overlying more clayey horizons. Organic matter produced in the topsoil is transferred in depth through the sandy horizons and accumulate at the transition, at a depth varying from 1 to more than 3 m, forming deep horizons rich in organic matter (Bh horizons). Although they cover great surfaces in the equatorial zone, these soils are still poorly known. Studying podzols from Amazonia, we found out that the deep Bh horizons in poorly drained podzol areas have a thickness higher than 1 m and store unexpected amounts of carbon. The average for the studied area was 66.7 ± 5.8 kgC m−2 for the deep Bh and 86.8 ± 7.1 kgC m−2 for the whole profile. Extrapolating to the podzol areas of the whole Amazonian basin has been possible thanks to digital maps, giving an order of magnitude around 13.6 ± 1.1 PgC, at least 12.3 PgC higher than previous estimates. This assessment should be refined by additional investigations, not only in Amazonia but in all equatorial areas where podzols have been identified. Because of the lack of knowledge on the quality and behaviour of the podzol organic matter, the question of the feedback between the climate and the equatorial podzol carbon cycle is open.

Abstract. Hydromorphic Podzol soils in the Amazon Basin generally support low-stature forests with some of the lowest amounts of aboveground net primary production (NPP) in the region. However, they can also exhibit large values of belowground NPP that can contribute significantly to the total annual inputs of organic matter into the soil. These hydromorphic Podzol soils also exhibit a horizon rich in organic matter at around 1–2 m depth, presumably as a result of eluviation of dissolved organic matter and sesquioxides of Fe and Al. Therefore, it is likely that these ecosystems store large quantities of carbon by (1) large amounts of C inputs to soils dominated by their high levels of fine-root production, (2) stabilization of organic matter in an illuviation horizon due to significant vertical transfers of C. To assess these ideas we studied soil carbon dynamics using radiocarbon in two adjacent Amazon forests growing on contrasting soils: a hydromorphic Podzol and a well-drained Alisol supporting a high-stature terra firme forest. Our measurements showed similar concentrations of C and radiocarbon in the litter layer and the first 5 cm of the mineral soil for both sites. This result is consistent with the idea that the hydromorphic Podzol soil has similar soil C storage and cycling rates compared to the well-drained Alisol that supports a more opulent vegetation. However, we found important differences in carbon dynamics and transfers along the vertical profile. At both soils, we found similar radiocarbon concentrations in the subsoil, but the carbon released after incubating soil samples presented radiocarbon concentrations of recent origin in the Alisol, but not in the Podzol. There were no indications of incorporation of C fixed after 1950 in the illuvial horizon of the Podzol. With the aid of a simulation model, we predicted that only a minor fraction (1.7%) of the labile carbon decomposed in the topsoil is transferred to the subsoil of the Podzol, while this proportional transfer is about 30% in the Alisol. Furthermore, our estimates were 8 times lower than previous estimations of vertical C transfers in Amazon Podzols, and question the validity of these previous estimations for all Podzols within the Amazon Basin. Our results also challenge our previous ideas about the genesis of these particular soils and suggest that either they are not true Podzols or the podzolization processes had already stopped.

Abstract:
Abstract Atotal of 212 soil profiles were described and assessed for physical and chemical properties during July 2006 as part of an Ecological Land Classification study along the Churchill River in central Labrador. Two major soil types were found in the study area along the Churchill River: Podzols and Organic soils. Podzolic soils covered approximately 60% and Organic soils occurred in 24% of the study area. Approximately 15% of the study area was classified as rock and other unconsolidated material. Summary results and a sub−set of the following soil units (from 10 soil profiles) are presented here and were distin− guished according to the Canadian System of Soil Classification (CSSC) (Soil Classifica− tion Working Group 1998): Orthic Humo−Ferric Podzol, Placic Ferro−Humic Podzol, Gleyed Humo−Ferric Podzol, Sombric Humo−Ferric Podzol, Gleyed Regosol and Orthic Luvic Gleysol. The basic properties of the soil units identified above included: (i) morpho− logical descriptions of soil profiles with differentiated horizons; (ii) field−texture tests were used to determine classes and physical properties of sands, silts, loams and occurrence of mottles; and (iii) a range of soil chemical composition of different horizons (e.g., pH, total organic carbon [TOC] and select metal concentrations) which indicated no anthropogenic contamination above background concentrations in the area.

Abstract:
In recent years, the number and intensity of forest fires has increased and thus more attention is paid to studying the pyrogenic soils. Parameters under study include, the post-fire return of phosphorus, alkali and alkaline earth metals, etc. from burnt plants and forest floor to the soil, but the related dynamics of iron and aluminum compounds has been poorly studied. However, these two elements are crucial for soil-forming processes and the productivity of many soils, in particular of the podzols under the most fire-hazardous pine forests in dry habitats. The present analysis comparative geographic is based on literature and original data related to podzols on quartz sand, in which the eluvial-illuvial distribution of sesquioxide compounds along its profile is one of important diagnostic features. An increase in the frequency of forest fires disrupts the bio-pedogenic accumulation of R2O3 in podzol profile. It is suggested that sorption on charcoal and detritus does not compensate for the removal of iron and aluminum from the podzol profile. The problems of taxonomy of post-pyrogenic soils are discussed.

Abstract:
Mountainous areas represent regions with specific soil cover pattern that is naturally given by an altitudinal gradient. The objective of our study was to describe the soil cover development on the altitudinal gradient under changed environment given by man-planted vegetation and acidification. The studied area is characterized by spruce monoculture planting that replaced the original broadleaf natural vegetation and high load of anthropic acidification. The common hypothesis considering the sequence of Dystric Cambisol-Entic Podzol-Haplic Podzol with increasing altitude was not proved. The results of our study indicate that the influence of spruce vegetation causes the occurrence of Haplic Podzols at low altitudes where the natural soil formation does not induce their development. Results showed that the vegetation type can overrule other altitude-related soil-forming factors. The conversion of natural broadleaf and mixed forests to spruce monocultures leads to the expansion of podzolization process to lower altitudes.

Abstract:
Soil solutions from an Orthic Ferro-Humic Podzol and a Typic Humisol were extracted using a soil to solution ratio of 1:10 by the batch and column procedures. The aluminum speciation in the extracts was determined by measuring three forms of dissolved aluminum (uncomplexed monomeric, total monomeric and total reactive). The two methods of extraction gave different results. For most of the mineral horizons and the moderately to well-decomposed organic horizons the batch method tended to extract more dissolved aluminum, particularly in uncomplexed monomeric form. The greatest differences between the two methods were for the lowest bulk density materials, the L and F horizons of the Podzol and the Of of the Humisol. The variations were due to channelling in the column and the inability of the shaker to assure good mixing between the soil and solution. It is concluded that the batch method is best suited for routine laboratory analyses. Key words: Soil solution chemistry, Podzols, Humisols

Abstract:
Abstract. Podzol-ferralsol soil systems cover great areas in Amazonia and in other equatorial regions, they are an end-member of old equatorial landscape evolution, are frequently associated with kaolin deposits and store and export large amounts of carbon. Their biogeochemistry was usually inferred from soil mineralogy and from spring or river water properties. This paper presents a database for groundwaters sampled in situ in a typical podzol-ferralsol soil catena from the Alto Rio Negro region, Brazil; the sampling periods allowed to sample under high- and low-level water-table conditions. The compositions of the groundwaters percolating the soil system are consistent with the currently observed mineral and organic paragenesis. The acidity and the site density of the dissolved organic matter (DOM) produced and circulating in the podzol white sand horizons are similar to what was observed in acid podzolic temperate zone. The aggressiveness of the white sand groundwater with regard to secondary minerals favours the podzol development at the expense of the ferralsolic or kaolin material. Some DOM is able to percolate in depth through clayey material with concentrations up to 9.7 mgC l−1 (4.0 on average). This DOM is characterized by high site densities indicating a large proportion of small carboxylic acids. In the deep kaolin and in the ferralsolic horizons, the Si and Al content of the groundwater is controlled by gibbsite and kaolinite precipitation/dissolution and by quartz dissolution. The mobility of Fe, mainly transported as Fe2+, is sensitive to small variations in EH. The bleaching of the deep kaolin at the upper part of the slopes is favoured by the high content of small carboxylic compounds and by the redox conditions of the solutions issuing from the podzolic horizons. The transfer of Al and Fe result in the precipitation of Al-nodules in slope horizons and of Fe-oxides in the upper downslope horizon. It can be inferred that thick bleached kaolin are likely everywhere presently active giant podzols are close to a slope gradient sufficient to allow deep percolation of groundwater.

Abstract:
The nature and properties of eight selected Podzols and Cambisols from the eastern United States and north-east Scotland were investigated to determine 1) their pedogenesis from physical, chemical, mineralogical, morphological and micromorphological properties, and 2) soil genesis relationships between the soils. Physical, chemical, mineralogical, morphological and micromorphological analysis were conducted on four soils from each country. The following physical and chemical analyses were conducted: particle size, pH by water, KCl and CaCl2, exchangeable bases, cation exchange capacity (CEC), percent base saturation (BS), KCl extractable H and Al, carbon determination, acid-oxalate extractable Al, Fe, Mn and Si, and dithionite-citrate-bicarbonate (DCB) extractable Al, Fe and Mn. The mineralogy of the very fine sand fraction was determined by grain counts, while energy dispersive x-ray analyses conducted on a scanning electron microscope (SEM-EDXRA) gave details of the composition of coatings, matrix material and other features of selected areas of thin sectors. Petrographic studies of soil thin sections revealed certain micromorphological characteristics and field descriptions gave information on the morphology of the soils. These investigations revealed a wide range of spodic expression in the soil profiles which depended greatly on the combination of parent material, climate, vegetation, relief and time. Of the eight soils studied, six were Podzols and the other two, although having characteristics of Podzols, were classified as Dystric Cambisols. A Carbic Podzol (Georgia) and a Ferric Podzol (New Jersey) both formed in sandy, base deficient coastal plain sediments on flat reliefs at low elevations in the eastern United States.

Abstract:
Three related aspects of the genesis and chemistry of Ferro-Humic Podzols in coastal British Columbia were investigated: micromorphology, phosphorus forms, and biological aluminum cycling. Profile morphologies display horizon disruption by slope instability and windthrow, with a patchy distribution of organic matter in the solum. Maximum C concentrations often occur at the base of the B horizon above a root-restricting layer. Channel-like features formed by root growth and decomposition provide important hydrologic pathways and may be either strongly enriched in organic matter (> 17% C) and Al, or partially eluviated. Microfabrics of surface organic and eluvial horizons resemble those of other forest Podzols. Organic matter-rich zones within B horizons have distinctive fabrics consisting of amorphous organic materials and/or humified, but recognizable, root detritus. Few living roots occur, suggesting that these features may be relict. Root residues appear to serve as deposition sites of Al and other metals. Such features appear to form through both in situ decomposition and illuviation, with little influence by faunal activity. Bhf horizon fabrics may be dominated by granular aggregates of presumed faunal origin, although with finer textures, microstructures tend to be more blocky. In coarser-textured B horizons, fabrics tend to be dominated by coatings and infillings of organic materials, often with a high proportion of recognizable plant tissue residues. Extraction data suggest the occurrence of allophanic materials in some B horizons with C contents exceeding 15%, with such cases associated with high Fe concentrations. Complex yellow and red colour banding in void infillings may indicate compositional zonation. A sequential phosphorus extraction and fractionation technique indicated a degree of weathering of primary phosphates comparable to that in Ultisols. Although total P was greatly depleted from eluvial horizons, organic P (Po) was dominant throughout the sola of eight profiles. Bicarbonateextractable Po, thought to be the most labile Po fraction, was more abundant than in many Mollisol A horizons. Correlations suggested a role for this fraction in supplying labile inorganic P in B horizons. Levels of resistant residual P in two regional groups of B horizons were directly related to Fe content. Al, organic matter, and Po levels are directly related in B horizons, suggesting a common illuvial origin. Annual return of Al in needle litter (approximately 1 kg ha⁻¹) was similar in both western hemlock and Douglas-fir stands. In fresh hemlock needles, much of the Al content is easily leached by dilute neutral salt solutions; comminution increases this extractability. During decomposition, the proportion of pyrophosphate-extractable Al increases, suggesting a shift to organic-complexed forms. Biologically-cycled forms may comprise much of the Al flux in the upper solum, with litter comminution by soil fauna partially controlling the rate of release during decomposition.

Mechanisms of interaction between uranium and colloids were studied by samples taken from a site of interest for the “French Nuclear Agency” (CEA). The mobilization of uranium from soils was apprehended by static and dynamic leaching experiments. The transfer and transport have been studied by considering pondwaters and drainwaters. Results confirm that anthropogenic uranium is more mobile than natural uranium. However mechanisms of mobilization and distribution of uranium, does not differ depending on its origin. The colloidal fraction plays an important role on the migration in soil and the transfer into water by representing from 10 to 90 % uranium depending on samples. The colloidal fractions of uranium are in a continuum of size up to about 200 nm hydrodynamic diameter. They are mainly composed of organic material, iron and aluminum. Along the drain, from the upstream to the downstream of the site, rearrangement of colloidal associations between uranium and organic material occurs in disfavor of colloidal associations between uranium and iron, the proportion of colloidal uranium bound to aluminum remains unchanged

Mestrado em Engenharia do Ambiente
Estima-se que a produção de cinzas de combustão de biomassa em Portugal ultrapasse, anualmente, as 90.000 toneladas. A sua aplicação no solo é uma possibilidade para a gestão deste subproduto. Por ser geralmente rica nesses elementos, a cinza pode fornecer ao solo nutrientes fundamentais para as plantas, como Ca, Mg, K, P ou Na. Contudo, pode conter igualmente alguns metais pesados, como As, Cd, Zn, Cr, Cu ou Pb. O objetivo deste trabalho é estudar o efeito da aplicação de cinzas no perfil do solo, bem como nos seus lixiviados. Para tal, foram testados, em lisímetros à escala laboratorial, dois tipos de solo: podzol e cambissolo. Foram utilizados, por ensaio, 4 lisímetros, com aplicação de material diferente: cinza; mistura de cinza e lama biológica (50:50), agente de calagem (CaO/CaCO3) e nenhum material, numa coluna de controlo. Os materiais foram aplicados às cargas de 1 ton.ha-1 (cambissolo) e 7,5 ton.ha-1 (ambos). Foi efetuada uma simulação de precipitação diária nos perfis de solo, sendo recolhido o lixiviado. No final do ensaio de lixiviação, os perfis de solo e lixiviados foram sujeitos a extensa análise (pH, CE, distribuição granulométrica do solo, quantificação de nutrientes e metais, etc.). A aplicação de cinza aumentou ligeiramente o pH dos solos, sendo esse efeito mais pronunciado nos lixiviados. Todos os materiais testados provocam aumento de condutividade elétrica quer no solo quer no lixiviado. Quanto ao enriquecimento em nutrientes, os resultados do cambissolo são globalmente melhores do que os do podzol, tendo a cinza provocado efeito em nada inferior ao agente de calagem. O aumento de carga tornou estes resultados mais notórios. A fração de elemento que é mobilizada para o lixiviado é invariavelmente bastante reduzida.
It is estimated that the production of biomass ash in Portugal exceeds 90.000 tons per year. Its application in soils is a possible way of managing this sub-product. Because it is naturally rich in such elements, biomass ash can supply essential nutrients for plant growth, such as Ca, Mg, K, P or Na. Nevertheless, it may as well contain some level of heavy metals, such as As, Cd, Cr, Cu, Zn, Ni or Pb. This thesis’ main goal was to study the effect of the application of biomass ash in the soil profile, as well as in its leachate. To this end, essays were made with four laboratory scale lysimeters, each one receiving a different material: biomass ash, ash combined with sludge (50:50 mix), a buffering agent (CaO/CaCO3), and no material in one lysimeter, which played the role of test control. Two classes of soil have been tested (podzol and cambissol) and two rates of product application have been used: 1 and 7.5 tons per hectare. A simulation of daily natural watering of the tested soils has been made, with collection of the resulting leachate. At the end of the leaching period, leachates and soil profiles were both extensively analyzed (pH, electrical conductivity, particle size distribution, quantification of nutrients and metals, etc.). Biomass ash application slightly elevated soil pH. The effect was superior in leachates. All tested materials produced raises in electrical conductivity, both in soil and leachate. In what nutrient enrichment is concerned, the results obtained for the cambissol were globally better than the ones obtained for the podzol. It has been noticed that the effect produced by the ash has been similarly good in comparison with the buffering agent’s effect. Increasing the application rate, the results tend to improve. The fraction of element that is mobilized in the leachate is invariably minimal.

É possível que micro-organismos envolvidos na degradação seletiva da MO sejam importantes para a gênese de Espodossolos, como observado anteriormente em Espodossolos de Bertioga e Ilha Comprida. O primeiro estudo teve como objetivo avaliar a variação espacial da estrutura das comunidades e a abundância de bactérias e fungos em três perfis de Espodossolos sob drenagem intermediária, nos diferentes horizontes e nas manchas brancas através de PCR-DGGE e quantificação por qPCR dos genes rRNA 16S de bactérias e ITS de fungos. O segundo estudo teve como objetivo avaliar a variabilidade espacial das comunidades de bactérias nos horizontes e nas manchas brancas de Espodossolos sob três regimes de drenagem, e determinar se a diversidade genética e estrutura das comunidades de bactérias estão associadas à composição molecular da MO nessas regiões, através do sequenciamento massivo da região V4 do gene do rRNA 16S de bactéria e análise de compostos orgânicos por pirólise-GC/MS. As estruturas das comunidades bacterianas, determinada por PCR-DGGE, nos diferentes horizontes de cada perfil foram mais similares entre si do que nos mesmos horizontes em diferentes perfis de Espodossolos. A estrutura das comunidades fungos não apresentou diferenças significativas, independente da localidade do perfil e profundidade dos horizontes. A abundância de cópias do gene rRNA 16S e região ITS, determinada por qPCR, foi maior no horizonte A do que no horizonte Bh, para os três perfis de Espodossolos estudados. Apesar de não haver diferenças significativas na estrutura das comunidades, grupos específicos de bactérias e fungos podem estar envolvidos na degradação seletiva da matéria orgânica nos diferentes horizontes, bem como nas manchas brancas e suas adjacências. A estrutura das comunidades de bactérias, determinada por sequenciamento massivo do gene rRNA 16S, nos horizontes mais superficiais (A e AE) foi distinta daquela observada nos horizontes mais profundos (EB, BE e Bh). Porém, as comunidades bacterianas nas manchas brancas e suas regiões adjacentes foram mais similares entre si, do que em relação as comunidades bacterianas nos horizontes, em todos os perfis analisados, independente do regime de drenagem. Acidobacteria, Proteobacteria e Actinobacteria foram os filos mais abundantes nos solos estudados. Actinobacteria e Alphaproteobacteria mostraram associação positiva com moléculas orgânicas derivadas da pirólise da lignina, as quais foram mais abundantes nos horizontes superficiais (A e AE), enquanto Acidobacteria mostrou associação positiva com compostos mais recalcitrantes encontrados em horizontes mais profundos (Bh), sugerindo um papel específico e diferenciado de cada grupo bacteriano na degradação de compostos orgânicos específicos. Os resultados desses estudos sugerem que grupos bacterianos específicos podem estar envolvidos na gênese de Espodossolos através da degradação de compostos orgânicos específicos em diferentes horizontes.
Podzols are highly frequent soils in the coastal plains of the São Paulo State, and are characterized by the presence of a spodic horizon (Bh or Bhm). Studies on the pedogenetic processes in Podzols of tropical regions are scarce, as well as studies on the molecular characterization of their organic matter (OM) and on the microorganisms involved in their genesis. It is possible that microorganisms involved in the selective degradation of the soil OM are important for the genesis of Podzols, as previously observed in Podzols of Bertioga and Ilha Comprida. The aim of the first study was to evaluate the spatial variation of the community structure and abundance of bacterial and fungi in the different horizons, bleached mottles and their immediate vicinity of three Podzol profiles under intermediary drainage regime, using PCR-DGGE and qPCR of the bacterial rRNA 16S gene and fungal ITS region. The aim of the second study was to determine the spatial variability of the bacterial communities in the horizons and bleached mottles of Podzols under three drainage regimes, and whether the bacterial genetic diversity and community structure were associated to the molecular OM composition, using high-throughput sequencing of the V4 region of the bacterial 16S rRNA gene and analyses of organic compounds by pyrolysis GC/MS. The structure of bacterial communities, determined by PCRDGGE, in the different horizons of each soil profile were more similar to each other than in the same horizons of different soil profiles. The fungal community structures did not show significant differences, independent of the soil profile location and horizons depth. Abundance of copies of the bacterial 16S rRNA gene and fungal ITS region, determined by qPCR, was higher in the A horizon than in the Bh horizon, for the three Podzol profiles studied. Even though there were no significant differences in community structures, specific groups of bacteria and fungi may be involved in the selective degradation of organic matter in different horizons, bleached mottles and their immediate vicinity. The bacterial community structures, determined by highthroughput sequencing of the 16S rRNA gene, in the surface horizons (A and AE) were distinct of that in the deeper horizons (EB, BE and Bh). However, the bacterial community structures in the bleached mottles and their immediate vicinity were more similar to each other than to the community structures in the horizons, in all profiles studied, regardless of the drainage regime. Acidobacteria, Proteobacteria and Actinobacteria were the most abundant phyla in the soils studied. Actinobacteria and Alphaproteobacteria showed a positive relationship organic compounds derived from lignin degradation, which were more abundant in the surface horizons (A and AE), whereas Acidobacteria showed a positive relationship with more recalcitrant compounds detected in deeper horizons (Bh), suggesting a specific and distinct roles of each bacterial group in the degradation of specific organic compounds. The results of these studies suggest that specific bacterial groups may be involved in the genesis of Podzols by degrading specific organic compounds in different horizons.

Abstract:
The reaction of sulfate with six podzolic horizons of the Southern Laurentians (Quebec) was investigated using batch reaction techniques. It was demonstrated that sulfate sorption increased with decreasing solution pH to a maximum sorption capacity at around pH 4.0; below this pH retention decreased. This drop in sorption capacity was related to the partial dissolution of Al surface coatings. Indeed, the amount of native sulfate and the maximum sorption during the experiment were positively correlated (R$ sp2$ = 0.982, 0.800) with the oxalate extractable Al content of these forested soils. In all six horizons, the increase in sulfate sorption as a function of equilibrium sulfate concentration was best described by the Gunary equation. Kinetic experiments showed the presence of two major stages in both sorption and desorption reactions with an initial quick change (first 6 h) in solution concentration being followed by a second step where the reactions between sulfate and the soil matrix were much slower. The time-dependence of these reactions emphasized the appropriateness of kinetic equation in describing field situations. Moreover, kinetics studies performed under highly acidic conditions demonstrated that the amount of sulfate sorbed decreased with time after an initial sorption step due to the partial dissolution of Al surface materials. Thermodynamic calculations further suggested the subsequent precipitation of jurbanite. It was then concluded that surface dissolution and mineral formation should be considered in the interpretation of results obtained from experiments aimed at determining the effect of pH on sulfate retention.

Abstract:
The article presents the results of a comparative assessment of grain productivity and adaptability indicators of various varieties of yellow lupine cultivated on soddy-podzolic sandy soil. We studied 8 varieties of lupine of domestic selection of the All-Russian Research Institute of Lupine, Novozybkovskaya SHOS; neighboring countries - Belarus and foreign selection (Germany), as well as the hybrid material of the Novozybkovskaya SHOS for 2016–2020. The adaptability of variety samples was comprehensively tested in terms of environmental stability and plasticity, using the criterion of "yield". Changes in meteorological conditions over the years of research made it possible to objectively assess the variation in the productivity of lupine by grain. For five years of testing, the grain yield varied from 6.4 c/ha Vladko (Belarus) to 11.8 c/ha, Novozybkovsky 100 (Novozybkovskaya SHOS). On average, changes in the productivity of varieties of VNII lupine from 9.7 to 11.3 c/ha, Novozybkovskaya SHOS – 10.7–11.8 c/ha, Belarusian breeding – 6.4–9.1 c/ha, foreign – 8.3–8.7 q/ha. Samples 5-10-84 (13.2 c/ha), 1-08-7-75 and 2-13-33 (12.7 c/ha) and 7-13-65 (12,5 q/ha). According to the set of indicators of adaptability, the All-Russian Research Institute of Lupine Nadezhny and Bulat turned out to be the best among the varieties; Belarusian selection Kastrychnik; Novozybkovskoy SHOS – Druzhny 165 and Novozybkovsky 100. From the hybrid material of the Novozybkovskaya SHOS promising numbers 1-08-7-75, 5-10-84, 4-12-302, 2-13-33, which have genetic flexibility, adaptability and stability in conditions of sandy and sandy loamy soils of the South-West of the Bryansk region.

Abstract:
In case of significant technogenic geochemical loads on agricultural landscapes, the issue of ecological forecasting of environmental management is particularly important. Scientific studies of this issue are aimed at establishing the critical values for the components of the ecosystem, the classification of technogenic sources of hazardous substances, levels of soil contamination. This study presents a research to determine the content of heavy metals in the soils of the Ryazan region (Russia) and analyzed the level of their pollution. In the experiments organic, organomineral and mineral fertilizers systems were studied. From 2002 to 2008 were conducted lysimetric experiments on detoxification of elevated pollution of sod-podzol sandy loam soil, and from 2006 to 2008 of podzolized black soil. The participation of the non-ferrous metals plant emissions was detected in the pollution of sod-podzol light in granulometric composition soils with copper of up to 80 mg·kg-1, when the average concentration of Cu in the soil was 38.8 ±6 mg·kg-1. Humification plays a significant role in the formation of soil, its most important properties and characteristics. The saturation of 1 hectare of sown area with organic was slightly different in the experiments, but the intensity of accumulation of humus from the various agrochemical means did not almost differ. The problem of adaptation of plants in the conditions of technogenic environment is of primary importance. Plants have three biobarera against the admission of toxicants, these are the soil – the root – the stem – the reproductive organs. Grain in contaminated soil is environmentally hazardous as the content of Pb is indicated at the level of 0.68, 1.17 mg·kg-1 (MPC 0.5), Cd – 0.27, 0.11 mg·kg-1 (MPC 0.1), Zn – 76 mg·kg-1 (50 MPC). Use of fertilizing systems had a mostly positive effect, but products do not always become environmentally friendly.

Abstract:
Microbial communities associated with the plant rhizosphere play an important role in carbon sequestration, regulation of nutrient cycling, and the efficient functioning of the ecosystem as a whole. The diversity of microorganisms inhabiting the plant rhizosphere and their complex interactions with the host plant significantly affect the morphology, physiology, growth, development, and health of plants. At the same time, it is known that the soil microbiome diversity is affected by the type of soil, the type of cultivated crop, and the method of tillage. In this study, the abundance and diversity of cultivated bacteria of the rhizosphere microbiome of wheat was assessed. Rhizospheric soil samples were taken from 5 fields with different types of soils (Greyzem, Chernozem, Podzols, Podzoluvisols, Podzoluvisols). Cultivated bacteria from the rhizosphere soil were isolated on meat-peptone and soil agars, and their number was determined. It has been established that the cultivated bacterial rhizobiome was least diverse in wheat plants grown on medium podzolic soil. The MALDI-TOF method was used to identify isolated cultivated isolate species. The genera Achromobacter, Acinetobacter, Bacillus, Microbacterium, Paenibacillus, Pseudomonas, Stenotrophomonas predominated among the isolated bacteria.

Abstract:
A través de la innovación teórica, la práctica política, la intervención social, la creatividad epistémica y la resistencia democrática muchas voces del Sur han emergido, en las últimas décadas, con fuerza y han entretejido estrategias para resistir a diferentes despojos y opresiones. El objetivo central que recorre este trabajo es escuchar las voces de mujeres indígenas —activistas, intelectuales, artistas, poetas, juristas, universitarias— con la finalidad de prestar atención a desafíos filosófico-políticos que ellas plantean y que se reflejan en innumerables luchas colectivas, podios de denuncia y constelaciones transnacionales. Para afrontar esta tarea se sigue como hilo argumental la exposición de distintas opresiones (patriarcal, de cuerpos y territorios y mediante el extractivismo cognitivo) y los desafíos para resistirlas (la “despatriarcalización” dentro de las tramas comunales, la producción de lo común y el reconocimiento de una espiritualidad y de transmisión epistémica a través de los textiles). La narración se acompaña de tres estrategias analíticas. Por un lado, una aproximación conceptual; por otro lado, una mirada contextual e histórica; y, finalmente, una escucha de prácticas y luchas.
