No-tillage (NT) has been adopted in organic agriculture as an alternative to conventional tillage (CT) for improving soil conservation. Cover crops (CC) play a vital role this process by providing straw and releasing nutrients into the soil. Therefore, study, we aimed evaluate effects of NT CT management on chemical properties bacterial diversity following cultivation diverse CC system. The experiment was conducted using randomized block design with subdivided plots, wherein plots...
The expansion of animal husbandry for food production has necessitated effective management livestock waste, including cattle manure and poultry litter. Using these byproducts as organic fertilizers in agriculture represents a sustainable approach to their disposal. While residues offer known benefits soil health crop productivity, further studies are needed explore the effect different microbiota on composition. objective this study was address gap contribute advancement area. A randomized...
Animal wastes have been commonly reused in agriculture due to improve organic matter and nutritional input. However, animal fertilizers can be sources of antimicrobials, bacteria resistant antimicrobial resistance genes. In this perspective, work aimed investigate the pr essence genes wastes, such as fresh bovine manure from conventional production systems, tanned poultry litter, litter bone meal. Sulfonamide were detected all residues. On other hand, colistin carbapenem not any samples. A...
Rivers provide essential water resources for humans. However, appear to be reservoirs of antimicrobial-resistant genes and dispersal routes resistant pathogens because human activities promptly influence them. Sediments are the most propitious substrates bacteria survival can act as an antimicrobial reservoir. Three sediment samples were collected upstream catchment point Guandu Water Treatment Plant (ETA Guandu) evaluate microbial diversity resistance sulfonamide (sul1, sul2), tetracycline...
Bovine mastitis is a complex disease that brings great losses to the dairy producer. The microbial diversity of soils, as well presence resistance genes in environment directly influence maintenance farm. objective this work was analyze bacterial pasture soils family farm, detecting enterobacteria may be involved etiology bovine mastitis, and detect encode broad-spectrum betalactamases these soils. Twelve soil samples, representative different areas farm located municipality Barra do Piraí,...
