Book Synopsis Impacto de sistemas de integração lavoura-pecuária na qualidade física do solo by : GLENIO GUIMARÃES SANTOS Santos
Download or read book Impacto de sistemas de integração lavoura-pecuária na qualidade física do solo written by GLENIO GUIMARÃES SANTOS Santos and published by . This book was released on 2010 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Na medida em que se intensifica o uso agrícola, os atributos físico-hídricos do solo sofrem alterações, geralmente adversas ao crescimento vegetal e essas modificações ficam mais nítidas, quando os sistemas de uso do solo são comparados com o estado do solo ainda sob vegetação natural do cerrado. A utilização do sistema de integração de lavoura-pecuária pode acarretar mudanças acentuadas nos atributos físicos, químicos e biológicos do solo e podem afetar o desenvolvimento e, consequentemente, a produção das culturas que venham em sequencia ao pastejo. Este estudo teve como objetivo geral analisar quantitativamente, por meio de atributos físico-hídricos, as principais alterações na qualidade do solo, decorrentes da utilização do longo prazo em sistema de integração de lavoura-pecuária, conduzidos em ambiente de cerrado. O estudo foi realizado a partir da abertura de trincheiras na Fazenda Capivara, Embrapa Arroz e Feijão, e em área particular, ao lado da propriedade da Embrapa, onde amostras de solo foram coletadas nas profundidades: 2,5-7,5 cm, 12,5-17,5 cm, 22,5-27,5 cm, 72,5-77,5 cm e 142,5-147,5 cm. As avaliações foram realizadas em seis sistemas, com área media de 13,5 hectares cada, sendo caracterizadas pelo seu uso atual como: sistema P1 (pastagem de Encachiaria brizantha com quatro ano de uso); sistemas P2 (pastagem de Encachiaria brizantha com dois ano de uso); sistemas P3 (pastagem de Encachiaria brizantha com três anos de uso); sistema C1 (soja sob plantio direto); sistema C2 (arroz sob plantio convencional) e; C3 (milho + Encachiaria brizantha sob plantio direto). Foi também usada uma sétima área de cinco hectares, mantida sob pastagem continua de Encachiaria decumbens, por 19 anos após a implantação designada por CP e uma oitava área de cerrado nativo chamado CE. De forma geral, os atributos físicos-hídricos e dentre eles as curvas de retenção de agua do solo e os respectivos valores do índice-S são alterados, quando submetidos ao manejo com implementos agrícolas e ao pastoreio animal, se comparados a área de cerrado nativo, considerada área de referencia neste estudo. O uso do índice-S para avaliar a quantidade física do solo, do ponto de vista de sua estrutura de qualidade por meio da curva de retenção de agua pode ser uma opção viável, uma vez que não tem algumas das limitações encontradas no uso de outros indicadores de qualidade do solo. Contudo, sua aplicação demanda um numero maior de investigações regionalizadas para diferentes sistemas de manejo e plantas cultivadas, tipos de solo, clima, atividade biológica do solo, dentre outros, relacionados seus valores críticos a índices medi-os de produtividade agrícola, para que se possa utiliza-lo com segurança na determinação da qualidade física "efetiva" do solo.

Download or read book Beetles written by Camilla Stack and published by Nova Science Publishers. This book was released on 2014-01-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beetle species belonging to the coleopteran families Bruchidae, Curculionidae, Laemophoeidae, Silvanidae and Tenebrionidae, as well as beetle-like insects from the psocopteran family Liposcelidae, are responsible for serious damages to agricultural products and resources. These beetles can be primary and/or secondary pests, feeding on integral and healthy grains or attacking those already damaged. The affected grains lose weight and germination power, have nutritive value and vigor decreased, as well as have the hygiene and sanity conditions impaired. This book examines the biodiversity, ecology and role in the environment of beetles.

Book Synopsis Tropical Rain Forests by : Richard T. Corlett
Download or read book Tropical Rain Forests written by Richard T. Corlett and published by John Wiley & Sons. This book was released on 2011-03-03 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison exploded the myth of ‘the rain forest’ as a single, uniform entity. In reality, the major tropical rain forest regions, in tropical America, Africa, Southeast Asia, Madagascar, and New Guinea, have as many differences as similarities, as a result of their isolation from each other during the evolution of their floras and faunas. This new edition reinforces this message with new examples from recent and on-going research. After an introduction to the environments and geological histories of the major rain forest regions, subsequent chapters focus on plants, primates, carnivores and plant-eaters, birds, fruit bats and gliding animals, and insects, with an emphasis on the ecological and biogeographical differences between regions. This is followed by a new chapter on the unique tropical rain forests of oceanic islands. The final chapter, which has been completely rewritten, deals with the impacts of people on tropical rain forests and discusses possible conservation strategies that take into account the differences highlighted in the previous chapters. This exciting and very readable book, illustrated throughout with color photographs, will be invaluable reading for undergraduate students in a wide range of courses as well as an authoritative reference for graduate and professional ecologists, conservationists, and interested amateurs.

Download or read book Paleoethnobotany written by Deborah M. Pearsall and published by Academic Press. This book was released on 2013-10-22 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the approaches and techniques of paleoethnobotany--the study of the interrelationships between human populations and the plant world through the archaeological record. Its purpose is twofold. First, it assembles in one volume the three major methods of paleoethnobotany, the analysis of macroremains, pollen analysis, and phytolith analysis, for the student or professional interested in the field. Second, it presents on paleoethnobotanist's view of the discipline: its past, present, and future, its strengths and weaknesses, and its role in modern archaeology.ï A comprehensive reference work for archaeologists and paleobotanists interested in reconstructing interrelationships between humans and plants from the archaeological recordï The first general of work theory and methods to emerge from this subdiscipline which has developed during the past twenty yearsï Makes the approaches and techniques of this field more accessible to the general anthropological and botanical audiencesï Offers archaeologists a handbook of field sampling and flotation techniques as well as an introduction to methods of analysis and interpretation in paleoethnobotany
Book Synopsis Advances in Historical Ecology by : William L. Balée
Download or read book Advances in Historical Ecology written by William L. Balée and published by Columbia University Press. This book was released on 2012-09-18 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology is an attempt to understand the reciprocal relationship between living and nonliving elements of the earth. For years, however, the discipline either neglected the human element entirely or presumed its effect on natural ecosystems to be invariably negative. Among social scientists, notably in geography and anthropology, efforts to address this human-environment interaction have been criticized as deterministic and mechanistic. Bridging the divide between social and natural sciences, the contributors to this book use a more holistic perspective to explore the relationships between humans and their environment. Exploring short- and long-term local and global change, eighteen specialists in anthropology, geography, history, ethnobiology, and related disciplines present new perspectives on historical ecology. A broad theoretical background on the material factors central to the field is presented, such as anthropogenic fire, soils, and pathogens. A series of regional applications of this knowledge base investigates landscape transformations over time in South America, the Mississippi Delta, the Great Basin, Thailand, and India. The contributors focus on traditional societies where lands are most at risk from the incursions of complex, state-level societies. This book lays the groundwork for a more meaningful understanding of humankind's interaction with its biosphere. Scholars and environmental policymakers alike will appreciate this new critical vocabulary for grasping biocultural phenomena.

Book Synopsis Handbook of South American Archaeology by : Helaine Silverman
Download or read book Handbook of South American Archaeology written by Helaine Silverman and published by Springer Science & Business Media. This book was released on 2008-04-04 with total page 1228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perhaps the contributions of South American archaeology to the larger field of world archaeology have been inadequately recognized. If so, this is probably because there have been relatively few archaeologists working in South America outside of Peru and recent advances in knowledge in other parts of the continent are only beginning to enter larger archaeological discourse. Many ideas of and about South American archaeology held by scholars from outside the area are going to change irrevocably with the appearance of the present volume. Not only does the Handbook of South American Archaeology (HSAA) provide immense and broad information about ancient South America, the volume also showcases the contributions made by South Americans to social theory. Moreover, one of the merits of this volume is that about half the authors (30) are South Americans, and the bibliographies in their chapters will be especially useful guides to Spanish and Portuguese literature as well as to the latest research. It is inevitable that the HSAA will be compared with the multi-volume Handbook of South American Indians (HSAI), with its detailed descriptions of indigenous peoples of South America, that was organized and edited by Julian Steward. Although there are heroic archaeological essays in the HSAI, by the likes of Junius Bird, Gordon Willey, John Rowe, and John Murra, Steward states frankly in his introduction to Volume Two that “arch- ology is included by way of background” to the ethnographic chapters.

Download or read book Slash-and-Burn Agriculture written by Cheryl Palm and published by Columbia University Press. This book was released on 2005-08-17 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caused in part by the slash-and-burn practices of both large- and small-scale farmers, the environmental implications of tropical deforestation remain a worldwide concern. Yet the small-scale farmers who use slash-and-burn agriculture depend on it to produce food and make a living for their families. With contributions from scientists, economists, ecologists, and anthropologists, this book provides an overall analysis of the environmental, economic, and social reasons for why slash and burn is so common and presents alternatives to this destructive practice.
