Available in PDF, EPUB and Kindle. Book excerpt: A utilização de herbicidas pode modificar a dinâmica do nitrogênio nos agroecossistemas e, como consequência, a disponibilidade do nutriente às plantas e microrganismos. Estas mudanças podem ocorrer devido às alterações fisiológicas ocasionadas nas plantas e/ou devido ao efeito dos herbicidas na atividade e composição da comunidade microbiana do solo, a qual tem funções importantes nas transformações do N no sistema. Neste contexto, objetivou-se com este trabalho de tese: 1- avaliar as perdas de nitrogênio do sistema solo-planta, sem distinção às vias de saída, após a aplicação de herbicidas em Pennicetum glaucum, Avena strigosa e Brachiaria ruziziensis; 2- avaliar a concentração de NH4 + na planta, a emissão de NH3 via foliar e a volatilização de NH3 pelo solo após aplicação de glyphosate em B. decumbens; 3 avaliar a exsudação de compostos nitrogenados por B. decumbens após aplicação dos herbicidas glyphosate, glufosinato de amônio e paraquat; e 4 avaliar a mineralização do N da palha de P. glaucum e A. strigosa dessecados com herbicidas e o aproveitamento do N proveniente da palha por plantas de milho. O herbicida glyphosate aumentou a concentração de NH4 + em plantas de B. decumbens e, como consequência, a emissão de NH3 via foliar em duas espécies de plantas do gênero Brachiaria. A volatilização de NH3 pelo solo não foi afetada pela utilização do herbicida glyphosate. As perdas de N do sistema solo-planta foram maiores após aplicação dos herbicidas glyphosate e glufosinato de amônio em P. glaucum, B. decumbens e B. ruziziensis. No entanto, em A. strigosa as perdas não foram afetadas por estas moléculas. Os herbicidas glyphosate e glufosinato de amônio modificaram a partição do N nas espécies estudadas, ocorrendo redução no conteúdo de N nas folhas. As perdas de N do sistema e a partição do N nas plantas não foram afetadas pelo herbicida paraquat, aplicado em B. ruziziensis e A. strigosa. A exsudação de compostos nitrogenados foi maior após aplicação dos herbicid.

Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Available in PDF, EPUB and Kindle. Book excerpt: Known for its readability and systematic, rigorous approach, this fully updated FUNDAMENTALS OF ANALYTICAL CHEMISTRY, 9E, International Edition offers extensive coverage of the principles and practices of analytic chemistry and consistently shows students its applied nature. The book's award-winning authors begin each chapter with a story and photo of how analytic chemistry is applied in industry, medicine, and all the sciences. To further reinforce student learning, a wealth of dynamic photographs by renowned chemistry photographer Charlie Winters appear as chapter-openers and throughout the text. Incorporating Excel spreadsheets as a problem-solving tool, the Ninth Edition is enhanced by a chapter on Using Spreadsheets in Analytical Chemistry, updated spreadsheet summaries and problems, an "Excel Shortcut Keystrokes for the PC" insert card, and a supplement by the text authors, EXCEL® APPLICATIONS FOR ANALYTICAL CHEMISTRY, which integrates this important aspect of the study of analytical chemistry into the book's already rich pedagogy.

Available in PDF, EPUB and Kindle. Book excerpt: The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.

This important book comprisescomprehensive reviews of the current available information onmicroalgal culture, written by 40 contributing authors from aroundthe globe. The book is divided into four parts, with Part I detailingbiological and environmental aspects of microalgae with referenceto microalgal biotechnology and Part II looking in depth at majortheories and techniques of mass cultivation. Part III compriseschapters on the economic applications of microalgae, includingcoverage of industrial production, the use of microalgae in humanand animal nutrition and in aquaculture, in nitrogen fixation,hydrogen and methane production, and in bioremediation of pollutedwater. Finally, Part IV looks at new frontiers and includeschapters on genetic engineering, microalgae as platforms forrecombinant proteins, bioactive chemicals, heterotrophicproduction, microalgae as gene-delivery systems for expressingmosquitocidal toxins and the enhancement of marine productivity forclimate stabilization and food security. Handbook of Microalgal Culture is an essential purchasefor all phycologists and also those researching aquatic systems,aquaculture and plant sciences. There is also much of great use toresearchers and those involved in product formulation withinpharmaceutical, nutrition and food companies. Libraries in alluniversities and research establishments teaching and researchingin chemistry, biological and pharmaceutical sciences, food sciencesand nutrition, and aquaculture will need copies of this book ontheir shelves.

Book excerpt: This text considers grazing management from the viewpoint of the ecology of grazing systems and focuses on the interrelationships between plant and animal populations which affect the stability of such systems, and the output of animal products from them. Relates the steps in the production process to the grassy surface characteristics that influence plant and animal behavior and uses these relationships to create a practical framework for management decisions.
