ABSTRACT Antimicrobial resistance is a global public health concern that requires an integrated approach including human, animal and environmental health. Agricultural environments, such as soil, animal waste and irrigation water, play crucial roles in the dynamics of antimicrobial resistance, as they act as reservoirs and pathways for disseminating resistance determinants. However, these agricultural environments are still often underestimated or neglected in many studies. This study aimed to address antimicrobial resistance in agricultural environments in Brazil and summarize the current state […]

ABSTRACT Centipedes and millipedes promote important functions in the ecosystem. However, land use intensification in agricultural areas can reduce the abundance and diversity of these organisms. To understand the effect of grazing intensification on communities of centipedes and millipedes, we sampled these organisms in an integrated crop-livestock system (ICLS) experiment, cultivated for 13 years with soybean (Glycine max) in the summer and black oat (Avena strigosa) + Italian ryegrass (Lolium multiflorum) for cattle grazing in the winter. Treatments consisted of […]

ABSTRACT Atlantic Forest devastation has resulted in the search and introduction of management capable of promoting and reestablishing the quality and sustainability of the ecosystem. Agroforestry systems (AS) are recognized for many benefits due to their management. This study compares an agroforestry system macrofauna and physical and chemical soil properties to those of a secondary forest area in the Atlantic Forest biome in southeast Brazil. Agroforestry system with 8 years of establishment and the regenerating subcaducifolious tropical forest fragment with […]

ABSTRACT Sugar and alcohol production in Brazil comes from planting hybrids from the crossing of species belonging to the Saccharum Complex. However, little is known about the growth response of these genera to inoculation using a diazotrophic bacteria Nitrospirillum viridazoti strain BR11145, currently recommended in Brazil as an inoculant for sugarcane growth promotion. This study aimed to evaluate the initial growth of 12 sugarcane genotypes inoculated or not with the strain BR11145. After 109 days, plant growth, biomass and macronutrient […]

ABSTRACT Soil fauna is an important indicator of soil quality. This study aimed to evaluate soil fauna collected using pitfall traps and soil chemical and microbiological properties under different land uses in the Cerrado. The systems evaluated were soybean under 14-year no-till; soybean under 3-year no-till; eucalyptus rows; soybean grown between eucalyptus rows, and native Cerrado. Collected individuals were identified as classes, subclasses, order, or family classes. We evaluated the number of individuals trap-1 day-1, total richness, average richness, Shannon […]

25/Nov/2024

ABSTRACT Ants mediate ecosystem services that can modulate crop performance and overall agroecosystem functioning. Our study investigated how the activity of Solenopsis invicta Buren (Hymenoptera: Formicidae) influences soil chemical properties, soil silicon pools, and soil phytoliths. We hypothesized Solenopsis invicta Buren activity would increase the macronutrient content, available silicon for plants (PASi), and amorphous silicon (ASi) in nest soils, which is related to changes in the phytolith assemblage. This study was conducted on agricultural soil under organic management, covering an […]

ABSTRACT Theobroma cacao, the source for chocolate fabrication, is a high-value crop that faces challenges such as the impact of climate change, pathogens, and cadmium accumulation. Soil associated with T. cacao has been extensively studied, looking for bio-controllers and microorganisms capable of Cd accumulation. However, there is no information about the microbial structure and interactions occurring in soil associated with cacao wild relatives, which represent a repository for biological diversity and its potential for biotechnological applications. We performed an extracellular […]

ABSTRACT Carbon flows into and out of the soil are important processes that contribute to controlling the global climate. The relationship between soil organisms and the climate is interdependent since the organisms that contribute to carbon and greenhouse gas fluxes are simultaneously affected by climate change and soil management. Temperature, soil moisture, pH, nutrient level, redox potential and organic matter quality are key elements affecting the microorganisms involved in organic carbon flows in the soil. Climate, topography (slope and position […]

ABSTRACT Inoculating corn with diazotrophic bacteria as growth promoters has been demonstrated to be an efficient agricultural practice in Brazil, mainly due to the root stimulation they provide to plants. This study investigates the corn (Zea mays L.) root architecture in a greenhouse assay where A. baldaniorum Sp245 and H. seropedicae ZAE94 strains were inoculated and evaluated for 22 days under two N levels: 0.6 and 6 mmol L-1 of N. Short-term bioassays were conducted to assess the plant’s response […]

ABSTRACT State parks are integral protection units created to protect ecosystems. However, anthropic activities may have been previously performed before their creation, forming transitional areas. Studies that evaluate the modifications of edaphic properties in these environments are scarce. The aim of this study was to evaluate the changes in soil properties and litter stock in areas of eucalyptus-forest ecotones. Litter stock (Stocklitter) and total soil organic carbon content and stock (TOCsoil), weighted mean diameter (MWD), origin of aggregates (biogenic or […]
