This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: MANEJO DA ÁGUA COM VISTAS À OTIMIZAÇÃO DA NUTRIÇÃO DO ARROZ IRRIGADO. A adubação mineral visa prover, às plantas de arroz, nutrientes em quantidades suficientes para suprir o déficit estabelecido entre sua exigência nutricional e o suprimento do meio de cultivo. As quantidades requeridas variam, porém, em função da interação entre vários fatores: fertilidade do solo; sistema de implantação da cultura; condições climáticas; tipo de planta; características da cultivar e práticas culturais, em especial o manejo da água de irrigação. Com relação a este último fator, é reconhecida sua influência sobre a absorção de nutrientes pelo arroz irrigado. Variações no manejo da água, particularmente no período de irrigação, podem alterar a disponibilidade de nutrientes para o arroz e, conseqüentemente, requerer adequações nas recomendações de adubação. A Embrapa Clima Temperado durante vários anos realizou estudos para avaliar o efeito da época de início da irrigação definitiva e do manejo da adubação nitrogenada sobre o estado nutricional da cultura de arroz irrigado. Como resultado, foi proposto o processo agropecuário, descrito em documento anexo, mostrando que o atraso na entrada de água na lavoura de arroz em até três semanas após o início do perfilhamento favorece o estado nutricional da cultura, devido ao maior desenvolvimento radicular das plantas mantidas sob solo drenado por um período mais longo. Constitui-se, pois, em alternativa de manejo tecnicamente viável para a cultura de arroz irrigado.

Book Synopsis Pollution of Water Bodies in Latin America by : Leobardo Manuel Gómez-Oliván
Download or read book Pollution of Water Bodies in Latin America written by Leobardo Manuel Gómez-Oliván and published by Springer. This book was released on 2019-11-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.

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.

Book Synopsis Agriculture and Industry in Brazil by : Albert Fishlow
Download or read book Agriculture and Industry in Brazil written by Albert Fishlow and published by Columbia University Press. This book was released on 2020-08-04 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture and Industry in Brazil is a study of the economics of Brazilian agriculture and industry, with a special focus on the importance of innovation to productivity growth. Albert Fishlow and José Eustáquio Ribeiro Vieira Filho examine technological change in Brazil, highlighting the role of public policy in building institutions and creating an innovation-oriented environment. Fishlow and Vieira Filho tackle the theme of innovation from various angles. They contrast the relationship between state involvement and the private sector in key parts of the Brazilian economy and compare agricultural expansion with growth in the oil and aviation sectors. Fishlow and Vieira Filho argue that modern agriculture is a knowledge-intensive industry and its success in Brazil stems from public institution building. They demonstrate how research has played a key role in productivity growth, showing how prudent innovation policies can leverage knowledge not only within a particular company but also across whole sectors of the economy. The book discusses whether and how Brazil can serve as a model for other middle-income countries eager to achieve higher growth and a more egalitarian distribution of income. An important contribution to comparative, international, and development economics, Agriculture and Industry in Brazil shows how the public success in agriculture became a prototype for advance elsewhere.

Book Synopsis Presidents and Terminal Logic Behavior by : Genevieve M. Kehoe
Download or read book Presidents and Terminal Logic Behavior written by Genevieve M. Kehoe and published by Texas A&M University Press. This book was released on 2014-05-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presidents of nations with constitutionally imposed term limits are often viewed as growing weaker as they approach the end of their time in office. However, in this important new study, political scientist Genevieve M. Kehoe argues that because such chief executives are free from reelection constraint and often still enthusiastic to create a legacy by pursuing bold projects, they may accomplish significant initiatives. Kehoe has developed a concept for this which she calls “Terminal Logic Behavior” (TLB). Presidents and Terminal Logic Behavior: Term Limits and Executive Action in the United States, Brazil, and Argentina provides both case studies and quantitative evidence to show how US presidents of the last three decades have utilized decrees on foreign, domestic, and environment policy during their final months in office. She finds a systematic pattern of decree use consistent with the mark of TLB in a most unexpected place—presidents’ use of national emergency powers. In a careful comparative analysis, she also finds support for her argument in the Argentinean and Brazilian experience of the same period.
