Modelos de paisagem e susceptibilidade magnética na identificação e caracterização do solo

O conhecimento detalhado do solo e de seus atributos, ao longo da paisagem, é uma demanda permanente dos sistemas urbanos e agroindustriais, para o planejamento sustentável de uso e ocupação. O presente trabalho objetivou estudar o potencial de modelos de paisagem e susceptibilidade magnética na identificação e caracterização de latossolos, em Guariba (SP). Foram coletadas 514 amostras de solo, em 110,0 ha, às profundidades de 0,0-0,20 m e 0,60-0,80 m. Foram identificados diferentes compartimentos de paisagem, com base no modelo de superfície geomórfica e segmento de vertente. em cada compartimento de paisagem, foram abertas trincheiras, para classificação do solo. As amostras foram analisadas quanto à granulometria e atributos químicos, pH (água, CaCl2 e KCl), matéria orgânica, P extraível, K+, Ca2+, Mg2+ e H+ + Al3+. Também foram determinados os teores de SiO2, Al2O3, Fe2O3 e óxidos de Fe livres (Fe d) e pouco cristalizados (Fe o), nas amostras das trincheiras, além da susceptibilidade magnética (SM). Solos taxonomicamente iguais, porém em diferentes compartimentos da paisagem, apresentaram valores distintos, para os atributos estudados, indicando que os modelos de paisagem e a susceptibilidade magnética podem ser viáveis, como técnica de campo, para auxiliar no detalhamento da variação dos atributos do solo. A susceptibilidade magnética demonstrou ter potencial para delimitação das superfícies geomórficas mapeadas no campo, o que indica o seu potencial de uso, na identificação e caracterização de áreas mais homogêneas.

Persistência e liberação de macronutrientes e silício da fitomassa de crotalária em função da fragmentação

The persistence of straw, as well as the dynamics of nutrients release of it, are important aspects to consider in the choice of plants for composition of crop rotations in a no tillage system. Thus, the objective of this work was to evaluate the decomposition rate and macronutrients and silicon (Si) release from sunn hemp (Crotalaria juncea L.) phytomass, as a function of management, with and without fragmentation. A randomized blocks design, with four replications, in a factorial 2x6, constituted by two aboveground phytomass management after 75 days after emergence (with and without mechanical fragmentation) and six sampling times (0, 18, 32, 46, 74 and 91 days after management (DAM)), were evaluated the decomposition rate and nutrient release from sunn hemp biomass. The mechanical fragmentation of sunn hemp straw did not change the decomposition and macronutrients release. The maximum release rates occurred 0-18 DAM. Potassium is the most rapidly available nutrient, while the silicon is more slowly released to the ground. Over time there has been increasing Si content in the straw.

A amizade como paisagem conceitual e o amigo como personagem conceitual, segundo deleuze e guattari

This paper begins with the Proposal of a pedagogy of concept according to Deleuze and Guattari. On this basis, I emphasize and explore the assertion that every thought demands relational traces as their internal condition. Among the relational traces defined by this pedagogy of concept, I selected friend as a character who distinguishes a given thought. I try, after that, to define, generally what friend and the scene of friendship in Plato's, Nietzsche's, Heidegger's and Foucault's philosophies are.

Análise da evolução da paisagem no entorno da represa dos rios jaguari e jacareí, estado de são paulo, com base em sensoriamento remoto e SIG

The primary objective of this study is to evaluate by means of remote sensing and GIS, the landscape evolution around the Jaguari and Jacareí River Dam, located in the eastern section of the State of São Paulo, Brazil. For this purpose we used LANDSAT 5/YM and CBERS-2/CCD images from 1984/1985 and 2006, respectively, considering the following classes of land use: forest, cultivated forest, agriculture, urban areas and water bodies. The two selected dates reflect important changes in the region such as the installation of the dam and subsequent urbanization of parts of its margins and the enlargement of the Fernão Dias Federal Highway, which contributed to an increase of areas of anthropic activities in the studied region. The results also indicate an increase in areas covered by native and planted forests, thus confirming a similar trend in other areas of the State of São Paulo.

Paisagem natural paleógena da bacia sedimentar de São Paulo no município de guarulhos, estado de São Paulo

Paleogene sediments of this region represent a significant source of water for urban, industrial and agricultural activities. This basin is part of the Southeastern Brazilian Continental Rift, which occupies a large portion of this geographical area. This study aims to present the evolution of the natural Paleogene landscape, through an analysis of its stratigraphic intcrops and underground portions based on the concept of facies and facies associations. A total of nine clastic and separate lithofacies were recognized and grouped into two main facies associations. These data suggest the existence of two depositional interdigitated systems: fluvial braided fans, which were predominant in parts of the northern and central area, and another composed of lacustrine sediments found in its central-south region. The paleogeography herein outlined will help considerably in the detection of new areas for mineral and water resources prospection, as well as in urban planning projects of this region.

Dinâmica da paisagem do município de Cubatão: Crescimento entre portos, indústrias e a Serra do Mar

With more than 60% of its territory under environmental protection, the city of Cubatão shelters the Industrial Pole and is located midway of two great metropolitan regions of State of São Paulo: Grande São Paulo and Baixada Santista. Both the implantation of industries and the construction of highways stimulated a process of migration and irregular occupation of the territory, with significant loss of the original vegetal covering of Atlantic Forest, in addition to pollution of water resources and the soil. The present work analyzed the dynamics of the landscape of a stretch of the city of Cubatão, associated to the Highway System Anchietas-Imigrantes, on the basis of economic cycles and regional public policies, aiming at helping the urban and environmental planning of coastal cities. We used a temporal series of air photographs of five decades and bibliographical surveys on the description of the region occupation. A non planned urban expansion for the city was evidenced, closely related with regional economic cycles and road building, directed to areas adjacent to highways and railroads, marshland and flooded plains landfills and mounts hillsides, including areas near Serra do Mar State Park. One suggests that the questions of environmental and urban planning of coastal cities are dealt with in the regional domain and in a participative way on the basis of studies of economic expansion and tourist activities in Baixada Santista, guaranteeing the maintenance of the remainders of Atlantic Forest in São Paulo coast.

Evolução do rifteamento e paleogeografia da margem Atlântica Equatorial do Brasil: Triássico ao Holoceno

The Equatorial Atlantic Margin evolved from three rift systems recorded by a complex set of sedimentary basins developed since Upper Triassic to the Lower Cretaceous (Albian). The first rift system formed Foz do Amazonas Basin in Upper Triassic; the second phase formed Marajó Basin in Berriasian, a new rift in Foz do Amazonas Basin in Valanginian and Bragança-Viseu, Ilha Nova, São Luís e Barreirinhas basins in Aptian; the third phase formed Barreirinhas and Pará- Maranhão basins and a new rifting in the Foz do Amazonas Basin between the Aptian and Albian and evolved to continental break up. The main paleostress field during rift evolution was NE-SW and after the continental break up took the E-W direction, from the development of transform zones in the oceanic crust. From Miocene, South America was subjected to intraplate tectonics, which resulted in formation of E-W transcurrent faults that generated transtensive and transpressive segments that formed sedimentary basins and hills, resulting in changes in the drainage network. In Quaternary the landscape was modified by the last ice age that changed the sea level; the coastal drainage network was drowning resulting in the formation of the current line coast.
