ABSTRACT Phosphorus (P) is one of the most important nutrients for plant growth. In cassava, P promotes plant growth and alters the synthesis and accumulation of starch in the storage roots. This study aimed to understand the dynamics of the accumulation and distribution of biomass, P, and starch in cassava plants fertilized with or without P during long growth cycles. A randomized block design with a split-plot scheme and four replicates was used. Plots were represented by the application of […]

ABSTRACT Integration of systems with pastures, using silvopastoral systems, can increase soil carbon levels, optimize land use, improve the quality and productivity of agricultural products, and promote the conservation of environmental resources. This study aimed to evaluate the influence of management practices of marandu grass at eucalyptus shading levels in a silvopastoral systems, on organic carbon and nitrogen stocks, and soil chemical properties in the Brazilian Cerrado. Environments with different light availability in the plots (SPS 55-60, SPS 50-55, SPS […]

ABSTRACT Precision agriculture (PA) practices in banana production chains have received limited attention. Based on the literature, the investigation of spatial and temporal variability in banana orchards should be customized according to the characteristics of the crop. This study aimed to develop and evaluate methods for mapping the spatial variability in soil properties at row- and clump-resolutions in a banana orchard, and to generate row and clump maps with high-spatial-resolution soil property information. A banana orchard was investigated, and georeferenced […]

ABSTRACT Brazilian Soil Classification System (SiBCS) adopts a hierarchical approach to classify soils using specific diagnostic attributes. Organossolos (Histosols) class is differentiated according to its genesis, especially because the parent material is organic, thus requiring diagnostic attributes that describe the unique properties of soil organic matter (SOM). This study aimed to propose the use of labile organic carbon and the C and N contents of humic fractions and their ratios for the family and series levels of the Brazilian Soil […]

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), […]

ABSTRACT Reduced stability and structural resilience expose sandy soils to physical degradation under intensive production systems. This study aimed to evaluate the influence of different cover crops (CC) under no-tillage system (NTS) cotton cropping, grown either individually or in combination, on the soil physical quality (SPQ) of a sandy loam Oxisol (Latossolo) in southeastern Brazil. To quantify the effects of CC on soil physical quality indicators, an experiment in randomized blocks design was implemented with the treatments: CC1: single cultivation […]

ABSTRACT Flipped Classroom (FC) approach has gained widespread acceptance across various education levels, particularly in higher education settings. Flipped Classroom represents a method employed to stimulate student learning, enhance academic performance, and foster student motivation and engagement. This approach involves the utilization of pre-class materials such as recorded lectures and multimedia resources for student review, while class time is dedicated to exercises, projects, or discussions. Numerous studies have documented enhanced learning outcomes among students of mathematics and science through FC […]

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 The benefits promoted by arbuscular mycorrhizal fungi (AMF) to forest species seedlings include higher growth rate, better nutrition, and higher survival rates. Inoculation with AMF may facilitate revegetation of degraded lands, although it depends on symbionts and environmental conditions, such as soil P availability. In this sense, the lack of information justifies the carrying out of studies of this nature. We investigated the dependence and responsiveness of two forest species native to the Atlantic Forest, Pseudobombax grandiflorum and Bauhinia […]

ABSTRACT Current studies have highlighted a significant gender disparity in the field of soil science. However, the scarcity of research and data on this issue can hinder the urgent need to address it and effect meaningful changes. This was the first demographic survey of Brazilian soil science, focusing on gender composition over time at different academic and professional levels, as well as peer recognition. We examined the metrics of students and faculty from all Brazilian soil science graduate programs (2004-2021), […]
