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 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 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 Understanding methodological and environmental implications for coastal soil identification is essential for developing integrated approaches to land management that address soil physical and chemical aspects, environmental dynamics, and their importance for coastal ecosystem sustainability. In this context, a study was conducted in a natural environment, near a marine extraction reserve that was degraded by irregular urbanization and road construction in Santa Catarina Island, Florianópolis, SC, Brazil. The study focused on identifying ecological patterns and impacts associated with acid-sulfate soils. […]

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 Soils of the Cerrados (Brazilian Savanna) are deep, well-structured, and well-drained, with flat to gently undulating terrain that favors mechanization for coffee cultivation. However, these soils are susceptible to compaction. This study aimed to assess the effect of mechanization on the physical characteristics of an Oxisol under irrigated coffee cultivation in the Alto Paranaíba-Minas Gerais State. We selected eight areas with different cultivars and years of Arabica coffee plantation, sampling five positions: right soil under the tree crown (RSC), […]

ABSTRACT Santa Catarina State, in the South region of Brazil, has 713 thousand hectares of pine forests. Harvesting operations of this species can degrade the soil, especially when carried out on very wet soil. However, there is little information on the impact of pine harvesting on the physical properties of the soil in this region. This study aimed to evaluate the impact of Pinus taeda L. harvesting on the physical properties of a Nitossolo Bruno distrófico típico. Two areas were […]

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 The absence of quantitative limits for the diagnostic attributes that define spodic B horizons in the Brazilian Soil Classification System (SiBCS) allows the inclusion of soils in the Espodossolos (the equivalent of Spodosols or Podzols) classes that contradict the classical concepts that define the podzolization process, by including horizons with low organic carbon (Corg) content, and with alkaline pH, high sum of bases and sodic or solodic characteristics. This study aimed to propose quantitative criteria and limits to identify […]

ABSTRACT Soil taxonomic systems seek to express pedogenic processes in their classes by choosing attributes or differential characteristics to identify classes at different categorical or hierarchical levels. Due to the advancement of knowledge, classification systems are periodically revised and/or expanded, and this may happen based on the evaluation of the database of these attributes or characteristics for a given class. In this context, the analysis of a broad set of Espodossolos (the equivalent of Spodosols or Podzols) from different pedoenvironments […]
