1. Relief Position and Soil Properties under Continuous Banana Cropping in Subhumid Climate in Northeast Brazil
ABSTRACT Sequences of thick and eroded soils in hills surfaces are cultivated with banana since the beginning of the last century in the Northeast of Pernambuco (PE), Brazil. Measurements of soil properties depending on soil slope under intensive agricultural cultivation are limited mostly as the pedogenetic approach. This study aimed to identify the dominan

2. Validation of a Standard Operating Procedure (SOP) for Forensic Soils Investigation in Brazil
ABSTRACT Soil traces are useful as forensic evidence due to their potential to transfer and adhere to different types of surfaces on a range of objects or persons. Several works have been developed in forensic soils, under different analytical approaches. However, in Brazil, only the researches from the Group of the Federal University of Paraná have develop

3. Comportamento mecânico de solo argiloso estabilizado com resíduo de vidro pulverizado em moinho de alta energia e de bolas
RESUMO A capital do Estado Amazonas apresenta dificuldades na construção de pavimentos devido à predominância superficial de argila em seu perfil geotécnico. Tal material mostra-se inadequado para a construção de subcamadas dessas estruturas urbanas. Avaliou-se, no presente estudo, o comportamento mecânico do solo argiloso típico de Manaus-AM na sua

4. Weathering of Rhyolites and Soil Formation in an Atlantic Forest Fragment in Northeastern Brazil
ABSTRACT Weathering and pedogenesis have been studied for a wide range of rocks and climates around the world. However, the eruption of rhyolitic magmas is a rare geological event, which leads to few studies associated with the rhyolite-soil-landscape relationship. In this context, this study evaluated the influence of rhyolite weathering on the properties o

5. Mineralogy of the Clay Fraction and Chemical Properties of Soils Developed from Sedimentary Lithologies of Pirambóia, Sanga-the-Cabral and Guará Geological Formations in Southern Brazil
ABSTRACT Quali-quantitative and crystallographic characterizations of the different minerals of a soil are essential for the best evaluation of its genesis, degree of weathering, active pedogenetic processes, physical and chemical properties, and its potential reserve of mineral nutrients. This study presents the results of mineralogical investigations carri

6. Iron oxides dynamics in a subtropical Brazilian Paleudult under long-term no-tillage management
Replacing conventional tillage (CT) with no-tillage (NT) management alters the pedoenvironment and the rate of topsoil processes, with possible effects on dissolution processes associated with iron oxides and therefore soil mineralogy. This study aimed to determine the effect of NT on the content and distribution of types of iron oxides in a Rhodic Paleudult

8. Influência das propriedades físico-mecânicas e hídricas do solo na susceptibilidade a escorregamentos em vertente declivosa na Serra do Mar em Ubatuba, São Paulo / Influence of physical and mechanical properties of soil an hydro in susceptibility to landslides on steep slopes in the Serra do Mar, Ubatuba
The mass movements are natural phenomena of evolution of the slopes, but they cause great damage when being considered as a risk in one area if they have a vulnerability in the slope associated with human occupation or industry that brings risk population. The study area is located on the northern coast of São Paulo, Brazil. In the region of Serra do Mar, a

9. Alteração e alterabilidade de rochas básicas intrusivas metamorfizadas e filitos sericíticos da região do Quadrilátero Ferrífero e sua implicação no comportamento mecânico / Weathering and weatherability of metamorphised intrusive igneous rocks and sericitic phylites of the Iron Quadrangle and its implication on their mechanical behaviour
The present work presents the results of physical, mechanical and mineralogical study of two rock types commonly found at Quadrilátero Ferrífero region (Minas Gerais State, Brazil). The main purpose of the study was to characterize the weatherability of those rocks when exposed to weathering agents that may cause problems in some civil engineering works, m

10. DISPONIBILIDADE DE POTÁSSIO AFETADA POR CULTIVOS EM SOLOS COM LONGO HISTÓRICO DE ADUBAÇÃO / POTASSIUM AVAILABILITY AFFECTED FOR SUCCESSIVE CULTIVATIONS IN SOILS WITH LONG THERM FERTILIZATION
In soils containing minerals with potassium in non-exchangeable forms, crops uptake a larger amount of this nutrient than that the chemical method can extract, making more difficult the establishment of availability classes and sufficiency levels for potassium. The aims of this study were: a) investigate crop response with potassic fertilization in an Ultiso

11. A STUDY OF THE DISTRIBUITION OF 2,4-D HERBICIDE IN AGRICULTURAL SOILS OF THE REGION OF SÃO PEDRO DA SERRA -RJ, AND ITS ENVIRONMENTAL SIGNIFICANCE / ESTUDO SOBRE A DISTRIBUIÇÃO DO HERBICIDA 2,4-D NOS SOLOS DA REGIÃO DE SÃO PEDRO DA SERRA-RJ E SUA IMPORTÂNCIA AMBIENTAL
The São Pedro da Serra Region has two types of tillage for the sowing soil, the shifting cultivation is based on the soil area rotation and the traditional utilize high amount of agro-toxics products. The aim of this work is to study the 2,4 D herbicide fixation and mobilization from the soil characteristics and the tillage. The cultivated areas were divide

12. Pedological characterization of Brazilian archaeo-anthroposols: sambaquis from the lakes region (RJ) and indian dark earths from the low Negro/Solimões river region (AM) / Caracterização pedológica de arqueo-antropossolos no Brasil: sambaquis da Região dos Lagos (RJ) e terras pretas de índio na região do baixo rio Negro/Solimões (AM)
This work surveyed some anthropogenic soils, the so-called Archaeo-Anthroposols. Those soils show advanced degree of pedogenesis, displaying tokens of their anthropic origin such as chemical and mineralogical characters and soil micromorphology. Some pottery shards are also constantly found in places where pottery making peoples dwelt, as well as shells and
