ABSTRACT This study analyzes the scientific production about soils within cities in Brazil, the most populous country of Latin America, to highlight significant patterns and contributions and point out gaps and future challenges. A more robust literature about urban soils in Brazil started in the 90´s decade and has intensified since 2015. Papers are mostly published in Portuguese, majority performed in cities with more than 500,000 inhabitants, many of them located in the Southern and Southeastern regions, and mainly focused […]

Studies on soil characterization in unexplored regions, besides the generation of data banks for the soil classes of the country, also produce scientific information about soil properties, important for the development of good management practices and sustainable land use. One of the main soil classes in the semiarid region of Pernambuco State, the Regosols, cover about 27 % of the state area, and are used mainly for family agriculture. Due to different geological and climatic aspects Regosols with different chemical, physical […]

There is lack of research on Argissolos (Ultisols and Alfisols) in relation to theunderstanding of the pedologic variations. Variations can be analyzed by multivariate statisticsand the data numerically classified. The comparison between the numeric classification andthe hierarchical classification can contribute to the evolution of the Brazilian Soil ClassificationSystem (SiBCS). The aims of this research were to analyze the pedologic variation of Argissolosderived from sedimentary materials in the central region of Rio Grande do Sul and to validatethe organization of the […]

In the upper Jequitinhonha valley, state of Minas Gerais, Brazi, there are large plane areas known as “chapadas”, which are separated by areas dissected by tributaries of the Jequitinhonha and Araçuaí rivers. These dissected areas have a surface drainage system with tree, shrub, and grass vegetation, more commonly known as “veredas”, i.e., palm swamps. The main purpose of this study was to characterize soil physical, chemical and morphological properties of a representative toposequence in the watershed of the Vereda Lagoa […]
