Resumen (Introducción): Las zonas ribereñas proveen una amplia gama de servicios ecosistémicos, y en contextos urbanos de alta intervención humana, esta provisión puede ser especialmente importante. Sin embargo, a nivel mundial, los ecosistemas ribereños urbanos han sido altamente degradados. (Objetivo): Esta investigación analizó la dinámica espaciotemporal de cambio de cobertura de la tierra para un periodo de 30 años (1992-2022) en la microcuenca urbana del río Ipís, en la Gran Área Metropolitana (GAM) costarricense, y realizó una valoración de la condición ecológica de sus zonas ribereñas. (Metodología): Esto se realizó mediante técnicas geoespaciales de clasificación de imágenes satelitales y fotos aéreas, álgebra de mapas, cálculo de métricas de paisaje y utilización de un índice para evaluar integridad ecológica de riberas (índice QBR). (Resultados): En el periodo estudiado, en la microcuenca del río Ipís hubo un aumento significativo de las coberturas impermeables (66.6 %) a expensas de coberturas con mayor funcionalidad ecológica, y ha habido una mayor fragmentación y aislamiento de parches de coberturas más permeables. Los valores del índice QBR, además, sugieren una severa alteración y deficiente integridad ecológica en las zonas ribereñas de la microcuenca en general. (Conclusiones): La expansión de coberturas asociadas a usos urbanos ha sido prominente en la microcuenca del río Ipís en las últimas tres décadas, y la alta degradación en sus zonas ribereñas compromete la capacidad de proveer servicios ecosistémicos en este contexto de alta alteración antropogénica.

Abstract (Introduction): Riparian zones provide a wide range of ecosystem services, and in urban contexts with high human intervention, this provision can be especially important. However, urban riparian zones worldwide have been highly degraded. (Objective): This research analyzed the spatiotemporal dynamics of land cover change over a period of 30 years (1992-2022) in the urban micro-basin of the Ipís River in the Greater Metropolitan Area (GAM) of Costa Rica and evaluated the ecological condition of its riparian zones. (Methodology): This was done using geospatial techniques such as satellite image and aerial photo classification, map algebra, landscape metrics, and the use of an index for evaluating riparian ecological integrity (QBR index). (Results): During the study period, in the Ipís River micro-basin there was a significant increase in impervious cover (66.6%) at the expense of more pervious cover with greater ecological functionality, and there has been greater fragmentation and isolation of patches of more pervious covers. The QBR index values also suggest high alteration and poor ecological integrity in the riparian zones of the micro-basin in general. (Conclusions): The expansion of cover associated with urban uses has been prominent in the Ipís River micro-basin over the last three decades, and the high degradation in its riparian zones compromises the ability to provide ecosystem services in this context of high anthropogenic alteration.

Abstract (Introduction): The current cultivation of trees is insufficient to cover the national demand for wood, in this way small producers become an alternative solution to this situation, since despite having small areas, in the country there are abundant farms with these conditions; However, the current forest management scheme does not meet adequate standards for the incorporation of these small producers. (Objective): To present an adaptive forest management scheme (AFMS) to the needs of the small farmer, in addition, to demonstrate the institutional availability to change according to expert criteria. (Methodology): 1) the factors that influence the decision to adopt an agricultural or forestry production system were identified; 2) a profile of an ideal productive system that met the interests and preferences of the small producer was made, which was compared with the characteristics of agricultural and forestry production; 3) the proposal of an EMFA adjusted to the preferences and interest of the producer was made, which was also compared with the ideal profile; 4) three proposed change actions were presented to experts, obtaining different degrees of possibility of changes in the EMFA. (Results): The discrepancy of the forest management scheme for the cultivation of trees with the perspective that a small producer has on an ideal production system was evidenced, as well as the substantial improvement that an EMFA would have in the valuation of the small producer and the institutional availability to change the EMFA according to the perspective of the small producers. (Conclusions): The adjustment of the forest management scheme allows a greater adoption of the activity by the small producer, but it was recognized that any proposal that is made would be successful only if forest governance makes it more flexible and allows change.

Resumen (Introducción): El cultivo actual de árboles es insuficiente para cubrir la demanda nacional de madera, de este modo, los pequeños productores se tornan como una alternativa de solución ante esta situación, ya que pese a contar con áreas pequeñas, en el país son abundantes las fincas con estas condiciones; sin embargo, el esquema actual de manejo forestal no cumple con estándares adecuados para la incorporación de estos pequeños productores. (Objetivo): Presentar un esquema de manejo forestal adaptativo (EMFA) a las necesidades del pequeño productor, además de evidenciar la disponibilidad institucional al cambio, según el criterio experto. (Metodología): 1) se identificaron los factores que influyen en la decisión de adopción de un sistema productivo agrícola o forestal; 2) se realizó un perfil de un sistema productivo ideal que cumpliera con los intereses y preferencias del pequeño productor, el cual se confrontó con las características de la producción agrícola y forestal; 3) se efectuó la propuesta de un EMFA ajustado a las preferencias e interés del productor, que fue también confrontada con el perfil ideal; 4) se expusieron tres acciones de cambio propuestas ante expertos, obteniendo diferentes grados de posibilidad de cambios en el EMFA. (Resultados): Se evidenció la discrepancia del esquema de manejo forestal para el cultivo de árboles con la perspectiva que un pequeño productor tiene sobre un sistema de producción ideal, asimismo la mejora sustancial que un EMFA tendría en la valoración del pequeño productor y la disponibilidad institucional al cambio del EMFA, según la perspectiva de los pequeños productores. (Conclusiones): El ajuste del esquema de manejo forestal permite una mayor adopción del cultivo de árboles por parte del pequeño productor, pero se reconoció que cualquier propuesta que se realice lograría ser exitosa si la gobernanza forestal flexibiliza y posibilita el cambio.

ABSTRACT Tidal swamp lands offer potential for expanding rice cultivation, but developing hybrid rice (Oryza sativa L.) in these areas faces significant challenges. Key obstacles include seed availability, fertilizer requirements, water management infrastructure, capital constraints, farmers’ technical skills, pest and disease pressures, consumer preferences, and institutional complexities. Addressing these challenges requires technological interventions and institutional support. Proposed technological solutions cover variety selection, water management, land preparation, seedling practices, amelioration techniques, transplanting methods, fertilization strategies, and pest and disease control measures. These solutions aim to overcome limited seed availability, nutrient deficiencies, suboptimal water management, and pest infestations, maximizing hybrid rice productivity in tidal swamp areas. Institutional strengthening is crucial to tackle systemic barriers like ineffective farmer associations, inadequate extension services, and limited market access. Collaborative efforts involving government agencies, research institutions, farmer groups, and market stakeholders are essential to unlock the full potential of hybrid rice cultivation in tidal swamp lands. By addressing these challenges and implementing targeted interventions, Indonesia can enhance its production sustainably, contributing to national food security and agricultural development goals in line with its vision to become a global food granary by 2045. The development of hybrid rice in swamp areas requires in-depth, on-site research to identify suitable varieties, taking into account soil fertility, hydrological conditions, and seasonal variations. By utilizing local or well-adapted genetic resources, it is possible to ensure the timely and cost-effective production of seeds in large quantities.

Water scarcity is a global problem exacerbated by the ever-increasing population and climate change, especially in arid and semi-arid regions. Different water resource management strategies, such as rainwater harvesting, have been proposed and implemented worldwide to combat water shortage. Mapping of the optimum sites where these rainwater harvesting structures can be constructed is very important. The main objective of this study was to map and identify, using GIS, optimum sites for the construction of rainwater harvesting structures (farm ponds, check dams and percolation ponds) for agricultural and peri-urban purposes in Eswatini. The optimum sites were identified by overlaying various thematic layers including land use and cover, slope, runoff potential, soil texture and depth and drainage density using ArcGIS 10.8. A general rainwater harvesting suitability map was produced for Eswatini, then potential sites for different rainwater harvesting structures were identified. The results of the study indicated that all three rainwater harvesting structures have suitable sites where they can be constructed. Check dams have potential sites which cover 22.7% of the suitable area in Eswatini, while farm pond and percolation pond sites covers 19.7% and 65%, respectively. Information on existing structures such as dams and earth dams for water storage may need to be gathered to verify the proposed sites of the rainwater harvesting structures. This study was able to identify new sites where structures can be constructed for rainwater harvesting which can improve water availability during dry seasons. Further evaluation may need to be done before implementation of these structures. Moreover, implementing this is subject to a number of other factors, such as the economy, feasibility studies as well as social implications. However, the results of this study will assist policy and decision makers in planning for potential sites for water storage as an adaptation to drought and climate change.

Resumo A corrosão em estruturas de concreto armado tem se tornado uma preocupação crescente, principalmente devido aos fatores relacionados às mudanças climáticas, como o aumento dos níveis de dióxido de carbono, mudanças de temperatura e precipitação. A fim de aplicar essas mudanças a estrutura, avaliações regionais são essenciais devido aos impactos ambientais variados. Este estudo examina a corrosão no Brasil, utilizando os níveis urbanos de CO2, utilizando a NBR 6118 (2023) para prever a despassivação, as fissuras iniciais e a falha devido a deslocamentos excessivos (Estados Limites de Serviço). Os resultados indicam uma probabilidade de despassivação de 50% em 13 anos para um cobrimento de 2,5 cm no pior cenário. Além disso, a probabilidade de falha por deslocamento excessivo sofre uma influência significativamente do diâmetro das armaduras, com um aumento de 311% ao longo de 45 anos ao usar um diâmetro de 5 mm em vez de 10 mm. Embora preliminar, este estudo também serve como um alerta para as construções futura e existentes, destacando a necessidade de pesquisas contínuas.

Abstract Corrosion in reinforced concrete structures has become a growing concern, primarily due to climate change-related factors such as the rise of carbon dioxide levels, temperature fluctuations, and altered precipitation patterns. To address this, regional assessments are vital due to varying environmental impacts. This study examines corrosion in Brazil, focusing on urban CO2 levels, employing NBR 6118 (2023) to predict depassivation, initial cracks, and failure due to excessive displacement (Serviceability Limit State). Results indicate a 50% depassivation probability within 13 years for a 2.5 cm concrete cover in the worst-case scenario. Additionally, the diameter of reinforcements greatly influences failure probability for excessive displacement, with a 311% increase over 45 years using a 5 mm diameter instead of 10 mm. These findings underscore the urgency of adapting construction practices to consider accelerated carbonation rates in urban environments and the need for ongoing research to refine predictive models and update construction standards accordingly.

ABSTRACT The article examines the impact of Ordinance GM/MS No. 1,262, published in September 2023, which links financial incentives to measurable outcomes in liver transplant programs in Brazil. The initiative, which considers the number of transplants performed and 30-day and 1-year survival rates, is viewed as progress toward greater accountability and improved patient care. However, the author highlights significant flaws in the current classification system that may undermine the principles of equity, universality, and decentralization of the Unified Health System [Sistema Único de Saúde (SUS)]. The payment model in use is outdated, does not cover the actual costs of transplants, and ends up using financial incentives to fill budgetary gaps rather than reward excellence in outcomes. Furthermore, the emphasis on the absolute volume of transplants disadvantages centers in smaller and less populated regions, making it harder for them to compete with large centers in more populous states. This exacerbates regional inequalities and encourages the centralization of transplant operations, contravening the SUS’s principle of decentralization. The author proposes adjustments to the system, such as updating the base payment to reflect actual costs, enabling all centers to operate with financial stability. It is also suggested that financial incentives reward excellence in outcomes and that the scoring system assigns greater weight to one-year survival rates, creating a fairer and results-oriented model. Proportional measures based on population size and redistributive funding for lower-ranked centers are recommended to promote equity and stability in transplant access. Ordinance GM/MS No. 1,262 is recognized as an initial milestone, but adjustments are needed to align quality and efficiency with the fundamental principles of the SUS, ensuring that all patients receive high-quality care, regardless of where they are treated.

RESUMO O artigo analisa a influência da Portaria GM/MS Nº 1.262, publicada em setembro de 2023, que vincula incentivos financeiros a resultados mensuráveis nos programas de transplante de fígado no Brasil. Considerando as taxas de sobrevida de 30 dias e 1 ano, bem como o número de transplantes realizados, essa iniciativa representa um progresso em direção a maior responsabilidade e melhor tratamento aos pacientes. No entanto, o autor chama atenção para falhas importantes no sistema atual de classificação que podem comprometer os valores de justiça, universalidade e descentralização do Sistema Único de Saúde (SUS). O modelo de pagamento atual é antiquado, não cobre os custos reais dos transplantes e acaba utilizando os incentivos financeiros para suprir déficits orçamentários, em vez de recompensar a excelência nos resultados. Além disso, o foco no número absoluto de transplantes prejudica os centros em áreas menores e menos habitadas, tornando mais difícil a competição com grandes centros em estados mais populosos. Isso agrava as desigualdades regionais e incentiva a centralização das operações de transplante, contrariando o princípio descentralizador do SUS. O autor sugere mudanças no sistema, como a atualização do pagamento base para refletir os custos reais, permitindo que todos os centros operem com estabilidade financeira. Também são recomendados incentivos financeiros que recompensem a excelência nos resultados e um modelo mais justo e orientado por resultados, com o sistema de pontuação atribuindo maior peso às taxas de sobrevida de 1 ano. Para promover equidade e consistência no acesso ao transplante, são aconselhadas medidas proporcionais ao tamanho da população e financiamento redistributivo para hospitais com menor classificação. Embora a Portaria GM/MS Nº 1.262 seja reconhecida como um marco inicial, mudanças são necessárias para alinhar eficiência e qualidade com os valores fundamentais do SUS, garantindo que todos os pacientes recebam um tratamento de excelência, independentemente de onde sejam atendidos.

Free-living amoebas (FLA) are ubiquitous protists found in the environment. They have shown exceptional resistance to environmental challenges and play significant roles in controlling microbial populations through their predatory behaviour and microbicidal activity in both soil and aquatic ecosystems environments. However, although rare, a limited group of FLA can cause serious infections in the central nervous system and other diseases, particularly in immunocompromised individuals with high mortality rates. They can also cause keratitis in otherwise healthy individuals. This review offers a comprehensive overview of freshwater naked amoebae but does not cover all aspects in detail. Its goal is to provide a historical context for our current understanding while addressing the most critical elements of FLA biology, their pathogenic potential, and their interactions with important human pathogens.

Resumen A Lei nº 12.651/2012 trouxe alterações nas larguras de Áreas de Preservação Permanentes (APPs) ripárias a serem restauradas, que passam a depender também do tamanho do imóvel rural em módulos fiscais, que por sua vez, varia conforme o município. Por conta disso, a definição do passivo ambiental dessas APPs é complexa, exigindo procedimentos de geoprocessamento e informações nem sempre prontamente disponíveis. Para automatizar a identificação destas áreas de passivo ambiental, foi criado o pacote restauraRapp, que apresenta um conjunto de funções para a automatização de quatro etapas do procedimento: I) Aquisição de dados; II) Classificação dos tamanhos dos imóveis; III) Processamento das informações sobre o uso e cobertura do solo em áreas ripárias; IV) Processamento e geração de resultados em formato cartográfico e tabular. O pacote gera resultados que podem auxiliar no planejamento de paisagens focado na recuperação de APPs ripárias, auxiliando ONGs, governos municipais e proprietários de terras.

Abstract The Law No. 12,651/2012 brought changes to the widths of riparian Permanent Preservation Areas (PPAs) to be restored, which now also depend on the size of the rural property in fiscal modules, which in turn, varies depending on the municipality. Because of this, defining the environmental liabilities of these PPAs is complex, requiring geoprocessing procedures and information that are not always readily available. To automate the identification of these areas to be restored, the restauraRapp package was created, which presents a set of functions for automating four steps of the procedure: I) Data acquisition; II) Classification of property sizes; III) Processing information on land use and cover data in riparian areas; IV) Cartographical and tabular output generation. This package can support landscape planning focused on the restoration of riparian PPAs, potentially assisting NGOs, municipality governments and landowners.

Abstract The integrated hydrothermal evolution of the large Santa Otília Paleodune from the Botucatu paleoerg and the cover Catalán Flow from the Serra Geral Group is here evaluated in Uruguaiana, southern Paraná Basin. Methods included satellite images, field surveying, petrography, and U-Pb geochronology of detrital and volcanic zircon. The tops of the compound linear-barchan paleodunes are exposed in the topographic highs. Rhombi and bowls at the top of the silicified sandstone units are significant, as is the poor preservation of eolian layering. The fishbone-shaped dune tops are surrounded by the lavas. The oxidized top of the flow (upper Tier 2) overlies the reduced base (Tier 1), which consists of exposed, massive rocks in creek beds that are light gray-colored and contain small (10 cm) agate geodes and numerous silicified sandstone dikes. The youngest dated zircon grains from the sandstone are 225–300 Ma old (one 175 Ma age), and the main older age peaks are 450–600 Ma (predominant), 900–975 Ma, 1800–1900 Ma, and 2500 Ma; few Archean 2.5 Ga ages. The strongly altered volcanic zircon preserved in the reddened Catalán Flow yields a concordia-intercept age of 137.3 ±7.6 Ma. Complex processes are thus constrained in the evolution of the Botucatu Formation and the first Serra Geral lava flow.

Abstract The expansion of the agricultural frontier driven by deforestation in the Amazon has promoted the increasing conversion of land use and land cover, where forests are being converted into pastures, and/or, with population growth, giving way to the creation of cities. This transformation in vegetation cover is reflected in the climatic elements, and consequently, in the response to microscale atmospheric phenomena. The most recent research carried out with observational data from the Large-Scale Biosphere-Atmosphere Program in the Amazon (LBA) indicates changes in biogeochemical water cycles such as reductions in rainfall between forested and non-forested regions. However, few studies evaluate the conversion of forests into cities. Therefore, this study aims to evaluate how the modification of the forest-city and forest-pasture land cover impacts the coldest days of the year when frontal systems incursion occurs, in the central region of Rondônia, southwest of the Amazon. The results indicate that the climatic elements are modified with the anthropization, however, between the anthropized environments no significant differences were evidenced. Forest conversion increased the temperature range by around 2 °C.

Resumo A expansão da fronteira agropecuária impulsionada pelo desmatamento da Amazônia tem promovido uma crescente conversão de uso e cobertura da terra, onde florestas estão sendo convertidas em pastagens, e/ou, com o aumento populacional, dando espaço à criação de cidades. Essa transformação na cobertura vegetal é refletida nos elementos climáticos, e consequentemente, na resposta aos fenômenos atmosféricos de microescala. As pesquisas mais recentes realizadas com dados observacionais do Programa de Grande Escala da Biosfera-Atmosfera na Amazônia (LBA) indicam alterações nos ciclos biogeoquímicos da água como reduções de chuvas entre regiões florestadas e não florestadas. No entanto, poucos estudam avaliam a conversão de florestas em cidades. Diante disso, este estudo tem como objetivo avaliar como a modificação da cobertura do solo de floresta para cidade e de floresta para pastagem impacta as variáveis micrometeorológicas no ano de 2017, em Rondônia, sudoeste da Amazônia. Os resultados apontam que os elementos climáticos são modificados com a antropização, no entanto, entre os ambientes antropizados não foram evidenciadas diferenças significativas. A conversão de florestas aumentou a amplitude térmica em aproximadamente 2 °C.

Due to the expansion of farming, many agricultural systems now depend more on chemical pesticides and inorganic fertilisers to boost farm output. Leguminous cover crops are used to improve soil fertility and to increase nitrogen availability for crop production. This review focuses mainly on evaluating the role of leguminous cover crops on soil's physical, chemical and biological properties. Furthermore, it focuses on the role of cover crops in crop biomass, grass nutritive value and crop-livestock grazing systems. This review used the Web of Science, Scopus and Google Scholar databases (accessed between January 2003 and December 2022). To find publications in the scope of the study, the authors combined different groups of keywords. The reviewed literature revealed that leguminous cover crops significantly increase yield due to an increase of nitrogen through nitrogen fixation. In addition, leguminous cover crops boost the forage's nutritional value, lowering feed costs and increasing livestock productivity. As a result of these findings, farmers can reap the benefits of leguminous cover crops in various ways, including enhancement of soil health, biomass, yield and reducing overall production costs.

ABSTRACT Desertification is the degradation process caused by climatic conditions and human activities that results in loss of soil productivity and decline in vegetation growth in the long term. Several indices related to vegetation, soil and climate are used to monitor desertification, but few studies explore qualitative and quantitative aspects of indices on desertification on spatial and hierarchical scale. This study aims to identify and measure indices related to increased risk of desertification on global, local and hierarchical scales using multinomial logistic regression models. Images from TM, ETM+ and OLI sensor from 1997 to 2018 in the end of dry and rainy seasons were used to quantify NDVI, TGSI, albedo, temperature, aridity index, evapotranspiration and precipitation on global spatial scale (Irauçuba Centro Norte) and local spatial scale (Miraíma, Canindé, Irauçuba and Santa Quitéria). GISD was calculated by geometric mean of weighted indices and segmented into 8 classes of susceptibility to desertification (hierarchical scale). The results showed that the best models were obtained on local scale and for the end of the rainy season. Temperature proved to be the most important variable for increased risk of desertification on global, local and hierarchical scales. Therefore, the increase in the risk of desertification in the studied areas is due to human activities of deforestation, overgrazing and fire. These factors contributed to reduction of vegetation cover and increase in temperature, changing the microclimatic, which led to decline in precipitation and worsening of desertification. term TM ETM 199 201 NDVI TGSI albedo temperature index Norte Miraíma, Miraíma (Miraíma Canindé Quitéria.

RESUMO: Entender aspectos da germinação de sementes de espécies nativas do Cerrado pode auxiliar na escolha de espécies a serem utilizadas na restauração de ecossistemas degradados. Portanto, o estudo teve como objetivo verificar o efeito de cápsulas biodegradáveis na germinação de sementes de três espécies arbóreas típicas de fisionomias florestais do Cerrado (Enterolobium contortisiliquum, Anadenanthera colubrina e Dipteryx alata). O experimento foi conduzido em casa de vegetação, com dois tratamentos: semeadura no interior de cápsulas biodegradáveis e semeadura direta na superfície do substrato. Duas sementes de cada espécie foram utilizadas por tratamento, as quais foram acomodadas em sacos plásticos com substrato arenoso oriundo da classe Neossolo Quartzarênico. Para cada tratamento, foram utilizados cinco blocos (repetições), com 20 sacos plásticos cada. A casa de vegetação teve condições controladas de temperatura e umidade relativa. Dentro das cápsulas, os resultados mostraram que as sementes de baru, angico-branco e tamboril apresentaram germinação de 97%, 42% e 12%, respectivamente. Por outro lado, na semeadura direta, a germinação foi de 15% para baru, 21% para angico-branco e 8% para tamboril. Os resultados indicam que o uso de cápsulas biodegradáveis favorece a germinação das espécies do Cerrado estudadas. Assim, tanto a utilização das cápsulas quanto as espécies elencadas são recomendadas em projetos de restauração ecológica.

ABSTRACT: A good grasp of the different facets of seed germination of the plant species native to the Cerrado will facilitate the selection of species that can be used to restore degraded ecosystems. Hence, the objective of the current study was to confirm the ways biodegradable capsules affect the germination of the seeds of three tree species typical of the physiognomies of the Cerrado forest (Enterolobium contortisiliquum, Anadenanthera colubrina and Dipteryx alata). The experiments, conducted in a greenhouse, included two treatments: seeding performed inside biodegradable capsules and direct seeding on the substrate surface. Two seeds from each of the species were sown in plastic bags containing the Quartzarenic Neosol class of substrates. Using five replicates for each treatment resulted in 20 plastic bags for each. The greenhouse conditions included controlled temperature and relative humidity. Inside the capsules, the findings revealed that the baru, angico-branco and tamboril seeds germinated at the rates of 97%, 42%, and 12%, respectively. However, during direct seeding, germination rates for baru, angico-branco and tamboril were 15%, 21% and 8%. From the findings, it is evident that when biodegradable capsules are used, the germination of all three Cerrado species investigated is favoured. Thus, both capsules and the cited species can be recommended for projects of ecological restoration.

RESUMO A Matéria Orgânica do Solo, é um dos mais importantes indicadores da qualidade e sustentabilidade dos ecossistemas nativos e cultivados, pois influencia os atributos químicos e físicos do solo, como a capacidade de troca catiônica, a agregação, a retenção de água e o fornecimento de nutrientes para as plantas. Este estudo teve por objetivo, avaliar os atributos físicos e a distribuição do carbono orgânico nos agregados de solos sob diferentes manejos. Foram coletadas amostras de solo deformadas e indeformadas nas camadas de 0-0,1 m; 0,1-0,2 m e 0,2-0,3 m, em manejos de produção conservacionistas (sequeiro e irrigado) e manejo de produção não conservacionista (sequeiro). Avaliou-se os atributos químicos, granulométricos, a densidade do solo e os teores de carbono orgânico nos macro e microagregados para os três manejos. Para os manejos de produção conservacionistas, além dessas análises, realizou-se a determinação do diâmetro médio ponderado, do diâmetro médio geométrico, do índice de estabilidade de agregados e da porosidade total do solo. Os dados foram analisados por meio dos testes Kruskal -Wallis e teste t, devido à ausência de delineamento experimental, e por parte dos dados, não atenderem o teste de Normalidade (ShapiroWilk). A densidade e a porosidade total do solo não diferiram nos manejos conservacionistas (sequeiro e irrigado). O manejo conservacionista irrigado teve agregados com maiores diâmetros médios ponderado e geométrico, e maior índice de estabilidade de agregados. Os manejos conservacionistas (sequeiro e irrigado) tiveram maiores teores de carbono orgânico nos macros e microagregados.

ABSTRACT Soil organic matter is one of the most important indicators of the quality and sustainability of native and cultivated ecosystems, as it influences the chemical and physical properties of the soil, such as cation exchange capacity, aggregation, water retention, and supply of nutrients to plants. This study evaluated the physical properties and distribution of organic carbon in soil aggregates under different management practices. Disturbed and undisturbed soil samples were collected in the 0.0-0.1 m, 0.1-0.2 m, and 0.2-0.3 m layers under conservationist (rainfed and irrigated) and conventional (rainfed) management. The chemical properties and particle size, soil density, and organic carbon content in macro and microaggregates were assessed for the three management types. For conservationist management, in addition to these analyses, the weighted mean diameter, geometric mean diameter, aggregate stability index, and total soil porosity were determined. The data were analyzed using the Kruskal-Wallis test and the t-test, as there was no experimental design, and some of the data did not meet the normality test (Shapiro-Wilk). Soil density and total porosity did not differ for conservationist management (rainfed and irrigated). The irrigated conservationist management exhibited aggregates with larger weighted and geometric mean diameters and a higher aggregate stability index. Conservationist management (rainfed and irrigated) showed higher organic carbon contents in macro and microaggregates. ecosystems capacity aggregation retention plants practices 0.00.1 0001 0.0 0.1 0 1 0.0-0. 0.10.2 0102 0.2 2 0.1-0. 0.20.3 0203 0.3 3 0.2-0. rainfed size types analyses diameter index determined KruskalWallis Kruskal Wallis ttest, ttest t test, t-test design ShapiroWilk.
