ABSTRACT Available phosphorus (P) content on bare soil surface and in runoff varies with the variation in the dose and form of P application and soil management. Phosphorus applied to recently cultivated, bare soil with minimal roughness remains on the surface, increasing the element content in the runoff. This study was carried out under simulated rainfall in a recently cultivated, bare, and minimally rough Cambissolo Húmico Alumínico, or Aluminum Humic Distrudept. Efect of phosphorus dosage on the element content in […]

ABSTRACT Agricultural yield depends on a series of ecosystem services provided by soil biota, among other factors. Soil management systems that are more sustainable than conventional tillage mitigate harmful effects to soil, improving the structure and function of the soil biota and facilitating ecosystem services. This study aimed to evaluate the effect of soil management practices on epigeic soil fauna and soil physical, chemical and microbiological properties. The experimental design was completely randomized, with the following treatments: NT – no-tillage; […]

ABSTRACT Dynamics of phosphorus (P) distribution, availability, and accumulation in reservoirs are influenced by land use and management. This study aimed to evaluate the total P (TP) content in soil aggregates formed under different vegetation cover types and agricultural crops, analyze the inorganic and organic forms of P with different degrees of lability, evaluate the percentage of P adsorbed (P ads), and, investigate the interactions between the soil aggregate P-fractions evaluated and their physical and chemical properties. Three different cultivated […]

ABSTRACT Phosphorus (P) is one of the most limiting elements for plant nutrition in tropical and subtropical soils due to its high binding energy on the surface of iron and aluminum oxides and hydroxides. Flooded rice cultivation occurs in lowlands, influencing redox reactions and P dynamics. This study aimed to evaluate the forms of phosphorus and their lability after soil reoxidation subsequent to a period of flooding for irrigated rice cultivation following four seasons of cultivation with soybean-ryegrass and corn-white […]

ABSTRACT Phosphorus in agriculture is an essential, limited, and strategic resource, and its sustainable management is a global challenge. Phosphorus (P) recovery as struvite (NH4MgPO4.6H2O) from manures and municipal and agro-industrial wastewaters has been considered one of the most sustainable technologies, based on the circular economy, to face challenges regarding P reserves and its use for conventional fertilizer production. Struvite is a slow-release P-fertilizer (5 % N, 12 % P, 10 % Mg), which could significantly reduce the Brazilian dependency […]

ABSTRACT Subtropical Oxisols have a high phosphate adsorption capacity and consequently lower phosphorus (P) availability. Therefore, correct management of phosphate fertilization in grain crop rotations is essential to increase the P-use efficiency and minimize potential environmental impacts. This study aimed to evaluate, in soils with medium and high initial P level, fertilization strategies (crop and system fertilization) and placement’s effects (banded P and broadcast) on soil available P, crop yield, and P use efficiency. Two field trials were installed on […]

ABSTRACT Knowing and defining the spatial and temporal variability of soil chemical properties becomes important for soil management. The definition of application zones in agricultural areas consists of dividing the area into homogeneous subareas, thus allowing the development of localized management. These zones can be defined by cluster methods and one of their advantages is to direct the determination of a future soil sampling, with a possible sample reduction. This study aimed to propose a methodology that integrates multivariate and […]

ABSTRACT Phosphorus is essential for plant metabolism. Although banana plants do not absorb large quantities, most of this mineral is exported together with the fruits, where the nutrients are related to sensory, nutritional, and technological qualities. Highly weathered soils, such as those found in most of Brazil, can immobilize phosphorus because of the cationic charges in iron and aluminum ions, making the element unavailable to plants and more challenging for phosphate fertilization. Brazil is the fourth-largest banana producer worldwide and […]

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 […]
