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 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 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 […]

RESUMO O sequestro de carbono orgânico do solo (COS) em terras agrícolas representa uma oportunidade significativa para mitigar as mudanças climáticas, removendo dióxido de carbono da atmosfera. Ferramentas de simulação são cada vez mais utilizadas para avaliar o impacto das mudanças climáticas e do manejo do solo na dinâmica dos estoques de carbono orgânico do solo. Embora os solos andinos normalmente armazenem grandes quantidades de carbono orgânico, práticas agrícolas, especialmente a aração, podem esgotar esses estoques, criando a necessidade de […]

ABSTRACT Extreme weather events, such as heavy rains and droughts, necessitate the rapid adaptation of production systems to prevent the degradation of natural resources and to maximize production potential. Defining adaptive practices requires an in-depth understanding of the factors that control the formation and propagation of surface runoff and the identification of specific practices tailored to each location. No-till system, coupled with complementary storm runoff management practices, is effective in controlling surface runoff and related processes. However, the planning of […]

ABSTRACT Wetlands provide important ecosystem services, including climate regulation through carbon sequestration and water storage. Identifying and protecting wetlands is a potentially significant opportunity for current global mitigation efforts. Cerrado wetlands commonly contain carbon-rich soils (peat); however, these environments have been neglected due to lack of knowledge on their characteristics and behaviors. Obtaining data in remote regions using a detailed sampling approach to characterize the organic carbon accumulation in these environments is extremely necessary. In this study, soil samples from […]

ABSTRACT Soil erosion in tropical environments causes environmental, social and economic damage. Canephora coffee crops are impacted by soil erosion and testing alternatives to mitigate this damage is a current need. This study aimed to evaluate the losses of sediment, organic carbon, nutrients and surface runoff caused by water erosion in between-rows spacing of Coffea canephora Pierre ex A. Froehner plants in management with and without cover crops, and the effect of the intensity of rains on sediment loss and […]

ABSTRACT Although the hydrological importance of water infiltration into the soil and surface runoff is well known, manual measurement of these processes, especially at the plot and hillslope scales, is laborious and requires a trained team. This study aimed to develop prototypes with the tipping bucket principle for the automatic monitoring of surface runoff at a plot scale (14.5 × 3 m). In total, 18 prototypes were built and installed in an experiment with different soil covers. Aspects of the […]

ABSTRACT Coconut palm cultivation is associated with the generation of a large amount of residues, mainly from coconut shells, and their utilization in agriculture can represent an opportunity in the context of circular economy and climate change. This study aimed to determine the effect of coconut shell deposition on carbon (C) stocks, organic matter quality, and soil water retention in coconut palm cultivation in the Brazilian semi-arid region. The study was conducted in a commercial coconut palm cultivation area in […]

ABSTRACT Soil organic matter (SOM) dynamics can be significantly influenced by various cultivation practices, particularly under environmental and edaphic conditions that enhance and accelerate the transformations of organic materials such as straw, root biomass, and organic fertilizers. This study aimed to evaluate the impact of different cultivation and soil management systems on SOM fractions in agricultural areas of the Cerrado Goiano region. The research was conducted across three areas with diverse production systems: 1) BV area, including soybean monoculture (SM01), […]
