Feuer and published by . This book was released on 1956 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: O leito da rocha viva da regiao e formado por gnaisses no terco sul-ocidental; xistos, resultantes de rochas sedimentares, no centro; e rochas sedimentares com dobras complexas no terco oriental. As rochas sao profundamente intemperadas. Encontram-se regolito de 10 a 60 pes de profundidade, em media, exceto nas areas litossolicas; o regolito encontra-se a maior profundidade na superficie de erosao mais antiga. A regiao e um peneplano intermitentemente levantado que apresenta distintas superficies de erosao. As duas superficies superiores, provavelmente do Terciario, sao designadas como primeira superficie de erosao (nivel do peneplano ou chapada) e segunda superficie de erosao, respectivamente, neste estudo. Uma terceira superficie de erosao, provavelmente doQuaternario, e representada em vertentes de vales com matas. Ocorre relicto de canga endurecida como uma orla quase continua, embora estreita, ao longo das margens dos remanescentes da primeira superficie de erosao, exceto nos testemunhos e divisores estreitos desta superficie. Nao ocorre nas superificies de erosaomais recentes nem como um lencol geral capeando a antiga superficie peneplana. Levanta-se a hipotese de que a canga se tenha formado apos o primeiro levantamento e depois do inicio da disseccao parcial. Levantamento posterior e uma consequente mudanca nos movimentos laterais de agua da subsuperficie pararam essencialmente a formacao da canga. A erosao geologica esculpiu as varias paisagens de superficie de erosao e expos a orla lateritica. Os ...
Book Synopsis The Cerrados of Brazil by : Paulo S.
Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.
Book Synopsis Soils and the Environment by : Gerald Olson
Download or read book Soils and the Environment written by Gerald Olson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we enter the last decades of the twentieth century, many persistent and perplexing problems continue to afflict humankind. Thus it is appropriate to address, in a new group of books, two of the monumental issues that haunt people throughout the world. Soils and the Environment by Professor Gerald W. Olson is the first book in this new publish ing program on Environment, Energy, and Society. The purpose of all these books will be to explore the many interrelated facets of these topics and to provide guidance for deal ing with problems and offering ideas for their solutions. Environment and energy are twin problems that occupy what many believe to be opposite sides of a two-headed coin. They are often viewed as being antithetical and incompatible. The various books in this program will try to place in perspective the options that are available to those who design policy and plan and manage societal matters. Typical of books being developed currently are ones on coal resources, environmental geoscience, environmental pollution, land-use planning, nuclear energy, mineral resources, and water resources. However, because soils are at the very heart of civilization and provide the building block for human sustenance, it is fitting to inaugurate this series with Dr. Olson's timely analysis of soils. Unfortu nately, these most vital resources seen. to have low priority in many farming enterprises, urbanization projects, deforestation schemes, and mining and developmental terrain changes.
Book Synopsis The Soils of Brazil by : Carlos E. G. R. Schaefer
Download or read book The Soils of Brazil written by Carlos E. G. R. Schaefer and published by Springer Nature. This book was released on 2023-05-23 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first comprehensive edition, in English, on the soils of Brazil, in the challenge of illustrating all the biomes of a country of truly continental dimension. In addition to presenting the first geosystemic view of Brazilian soils, in all geological, geomorphological and environmental aspects, the book also makes a key contribution to the discussion of current topics in Pedology, such as Anthrosols, Technosols, Soil Management trends and sustainability, Pedometrics and advanced techniques of digital soil mapping. The soils of Brazil were conveniently stratified into sectors and treated within the different biomes, without neglecting any area of the Brazilian territory. Considering the aspects of the landscape of occurrence, climates, geomorphology and geology, each pedological region was abundantly documented with soil profile data and many fine original, three-dimensional illustrations and diagrams, made with care by the authors. Among the regions, the most important are the forested Amazon, the Central Plateau with Cerrados, the Caatingas of the northeastern semi-arid region, the Atlantic Forest in all known variants; in addition, the Restingas, Mangroves, Oceanic Islands, Wetlands of the Pantanal and the subtropical regions of the Pampa and Matas de Araucaria. The book is of great importance as the first published work on Brazilian soils, but it is of great interest to geologists and geomorphologists who study the tropics and subtropics, due to the novelty and scope of the work.

Book Synopsis Assessment of the Nitrogen Mineralization Potential of a Brazilian Oxisol by : Kate Barger Showers
Download or read book Assessment of the Nitrogen Mineralization Potential of a Brazilian Oxisol written by Kate Barger Showers and published by . This book was released on 1977 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topsoil and subsoil samples were collected from the check (0 nitrogen added) plots of a nitrogen fertilizer experiment with maize located on a Oxisol in the Central Plateau of Brazil on land witch had been recently brougth into cultivation. The samples were evaluated for their potential to supply nitrogen to a crop by a standard incubation thechinique and by a chemical procedure whichi had shown some promise as a predictive tool for ather tropical soils. The results were compared with nitrogen uptake data available for a maize crop grown on these soils. A long term incubation study was also conducted in order to characterize the nitrogen release pattern of these soils. Al samples were extracted with 1 N KC1. The chemical test procedure, wich measure a fraction of the extractable organic and inorganic NH+4 involved the digestion of extracts with concentrated H2SO4 and analysis for NH+4 by stem distillation. Extracts from incubated and nonincubated soil were also analysed for mineral nitrogen by stem distillation. Difficulties were encountered in the analysis anlysis of these drak red Oxisols by the macro-Kjeldahl procedure. The number of samples was insufficient for a satisfactory interpretation of the correlations between the chemical soil test and crop nitrogen uptake data. The only strong relationship in the soil test data was that between Dmineralizable nitrogen and digest nitrogen. This would lend some support to the hypothesis that the digest nitron does measure some portion of the soil nitrogen which is potentially available to plants. The incubation studies showed a dofference between topsoils and subsoils in their patterns of release of NH+4 and NO-3; the topsoils showed rapid increases in the amounts of NO-3 and rapid decreases in NH+4 and decrease in NO-3. The values of Dmineralizable nitrogen from this study were similar to those report in the literature from incubation studies of soils with similar chemical properties from temperate and tropical regions. It can not be conclued that these Oxisols from the central Plateau of Brazil have the same potential for nitrogen production as temperate region soils, for the cropping historis of the various temperate and tropical aoils were different.
