Book excerpt: O sistema de plantio direto tornou-se, efetivamente, uma realidade no Cerrado brasileiro, sendo grande o número de produtores que já adotaram essa técnica. O não revolvimento do solo nesses sistemas, aliado à camada de resíduos que atua como dissipadora de energia, tem provocado mudanças nos fluxos de água nos sistemas palha-solo-planta-atmosfera. Como ainda não existe um modelo que avalie as modificações impostas ao balanço hídrico das culturas para as condições do Cerrado brasileiro, este trabalho objetivou quantificar, com o uso de modelo numérico, os efeitos da palhada sobre o balanço hídrico do milho e do milheto. Para isso, incorporaram-se novas funções ao modelo STICS (Simulateur mulTIsciplinaire de Culture Standard) para simular sequencialmente o crescimento e o rendimento das culturas do milho e do milheto no sistema de plantio direto no Cerrado. Foram estudados e quantificados os efeitos de vários níveis de resíduos de milho, milheto e soja na dinâmica da água no sistema de plantio direto. A modelagem desses efeitos foi feita mediante equações matemáticas simples e, posteriormente, incorporadas ao módulo de balanço hídrico do STICS. Os diferentes parâmetros e variáveis necessários para a avaliação do modelo foram coletados a partir de experimentos conduzidos no campo, onde se mediram a umidade do solo, a área foliar, a biomassa e o rendimentos de grãos. Pelos resultados observou-se que o STICS simulou satisfatoriamente a variação de água no solo e os componentes de produção das duas culturas. Uma vez calibrado, usou-se o modelo para avaliar o risco climático do milho nos sistemas convencional e plantio direto. Com base nos resultados obtidos, pode-se afirmar que o STICS é uma ferramenta eficaz para ajudar o sistema de auxílio às tomadas de decisão, pois, com os seu uso será possível indicar as áreas com maior potencial para o desenvolvimento do milho e avaliar a sensibilidade da sua produção nos sistemas de plantio direto e convencional.

Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

Available in PDF, EPUB and Kindle. Book excerpt: With a complex assemblage of largely intact ecosystems that support the earth's greatest diversity of life, the Amazon basin is a focal point of international scientific interest. And, as development and colonization schemes transform the landscape in increasing measure, scientists from around the world are directing attention to questions of regional and global significance. Some of these qustions are: What are the fluxes of greenhouse gases across the atmospheric interface of ecosystems? How mush carbon is stored in the biomass and soils of the basin? How are elements from the land transferred to the basin's surface waters? What is the sum of elements transferred from land to ocean, and what is its marine "fate"? This book of original chapters by experts in chemical and biological oceanography, tropical agronomy and biology, and the atmospheric sciences will address these and other important questions, with the aim of synthesizing the current knowledge of biochemical processes operating within and between the various ecosystems in the Amazon basin.

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.
