Available in PDF, EPUB and Kindle. Book excerpt: A soja constitui uma das culturas de maior relevância para a economia brasileira e, possivelmente, a que apresenta crescimento mais expressivo no cultivo e no segmento agroindustrial nacional (CHIAPPA apud FREITAS, RODRIGUES e SILVA,2006). Esta cultura é originária do Leste da Ásia (China) há cerca de cinco mil anos. No início, só encontrava-se variedades de soja selvagem de característica rasteira, mas com o tempo, sofreu diversos cruzamentos e obtiveram-se outras de porte ereto. O seu cultivo como exploração comercial iniciou devido aos Estados Unidos da América, onde a utilizou primeiramente como forrageira e ao passar dos anos como grão. No Brasil a cultura iniciou-se com testes no Estado da Bahia em 1882, com germoplasma trazido de baixas latitudes dos EUA, não tendo êxito na região. Algum tempo depois, foram trazidos e testados novos materiais no Estado de São Paulo que conseguiram melhores resultados, mas foi no Rio Grande do Sul que a cultura conseguiu se firmar. A cultura antes utilizada como forrageira para a alimentação do gado leiteiro e suíno, passou a ser cultivada como grão, e deu origem a subprodutos dos quais os principais são o farelo e o óleo e outros utilizados na indústria de alimentos e indústria química. Devido às pesquisas realizadas, conseguiu criar a primeira cultivar brasileira e adaptada às condições de solo e dima do país, favorecendo com que áreas antes consideradas improdutivas, como o Cerrado, viessem produzir e conseqüentemente ampliando nossas fronteiras agrícolas. Atualmente a cadeia produtiva da soja destaca-se como principal cultura explorada no mercado interno, como sendo o segundo maior produtor mundial, atrás apenas dos Estados Unidos, e o maior exportador. A produção de soja necessita de várias práticas complexas de manejo, e entre elas o controle de plantas daninhas desempenha um papel fundamental para a obtenção de altos rendimentos da cultura. A invasora prejudica a cultura, porque com ela compete pela luz solar, pela água e pelos nutrientes, podendo, a depender do nível de infestação e da espécie, dificultar a operação de colheita e comprometer a qualidade do grão (EMBRAPA, 2009). Dada a importância e a magnitude da cultura da soja no Brasil, é imprescindível aperfeiçoar a tecnologia de produção disponível, visando reduzir ao máximo as perdas impostas pela competição das plantas daninhas (CONSTANTIN et al., 2007). O estágio teve como objetivo de proporcionar o aperfeiçoamento acadêmico dos conhecimentos obtidos durante o curso, vivenciando e analisando as atividades desenvolvidas pela Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) por meio de acompanhamento e participação de diversas atividades na área de plantas daninhas, relacionadas principalmente aos sistemas de manejo dentro da cultura da soja e sua importância, plantas daninhas de ocorrência comum, dinâmica de populações (banco de sementes, emergência, sobrevivência), alternativas de controle de plantas daninhas, o uso de herbicidas e problemas de resistência, importância de coberturas vegetais (rotação de culturas) e efeitos de alelopatia, com fins de aplicá-Ios em um futuro próximo com o título de Engenheiro Agrônomo.

This book was released on 2022-09-12 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work covers many aspects of plant nematode management using organic strategies. These range from applications of latest understandings of fundamental concepts/mechanisms of nematode control, to modern tools and techniques used in efficacy evaluation. The Volume also includes some case studies/applied aspects of organic nematode pest management. Chemical and physical control measures used for nematode management have their own implications. Against this backdrop, organic management of plant nematodes appears as a more rational and sustainable approach. However, concise information on the current topic is scarce. This book is a sincere effort to bridge this void as we aim to provide the most updated, critical and in-depth knowledge synthesized by many experts working in the field of plant nematology, worldwide.

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.

Several aspects related to the conservation of natural enemies, such as vegetation design and climate change, are discussed in Part 1 and the bioecology of several insects groups used in biological control in Latin America is presented in Part 2. Part 3 is devoted to mass production of natural enemies while Part 4 describes how these insects have been used to control of pests in major crops, forests, pasture, weeds and plant diseases. Lastly, Part 5 reports Latin-American experiences of integration of biological in pest management programs.

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.
