This book was released on 2007 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Qual a importância da fixação biológica do nitrogênio para o Brasil e para o planeta? De modo sucinto, como ocorre o processo de fixação biológica do nitrogênio com a soja? De quanto nitrogênio a cultura da soja precisa para atingir altos rendimentos? Quando e por quanto tempo a soja consegue fixar N2? É necessário colocar uma dose inicial de fertilizante nitrogenado para suprimir sintomas de clorose? A aplicação de fertilizante nitrogenado em outros estádios do crescimento da soja é necessária para a obtenção de altos rendimentos? Por que é necessário inocular a soja em solos de primeiro cultivo? Áreas que estavam sob pastagens, com cana-de-açúcar, ou com outras culturas, há vários anos, podem ser consideradas como primeiro cultivo? Em áreas tradicionalmente cultivadas, vale a pena reinocular? Em uma área de cultivo recente, em que foi feito um trabalho cuidadoso de inoculação, ainda assim vale a pena reinocular? Ganhos de rendimento pela reinoculação também ocorrem em solos sob o sistema de plantio direto? Os incrementos no rendimento obtidos pela reinoculação compensam financeiramente? A demanda elevada da soja por N pode causar um balanço negativo desse nutriente para a próxima cultura? A soja transgênica também se beneficia da fixação biológica do nitrogênio? Como deve ser o inoculante para a soja? Quais bactérias devem estar no inoculante? E o número de células, é importante? Como fazer o cálculo teórico do número de células de Bradyrhizobium por semente? Como saber se o número de células do inoculante é adequado? Quais as vantagens do inoculante turfoso e em que dose ele deve ser usado? É importante usar uma substância adesiva para o inoculante turfoso? Os inoculantes líquidos são tão eficazes quanto os turfosos? Que cuidados tomar na hora da compra do inoculante? Como deve ser feita a inoculação das sementes? Inoculante turfoso e tambor rotatório, sem ou com fungicidas e os micronutrientes; Co e Mo; Inoculante turfoso e máquina de tratamento de sementes; Inoculantes líquidos; Qual o volume de água recomendado no caso de fungicidas e micronutrientes líquidos? No campo, quais os principais fatores limitantes à fixação biológica do N2? Fatores ambientais; Fatores nutricionais; Tratamento de sementes com fungicidas e inseticidas; Como compatibilizar o tratamento de fungicidas com a inoculação? É possível deixar de usar o fungicida nas sementes para evitar prejudicar a fixação biológica do nitrogênio? Se for necessário tratar as sementes com fungicidas, existe alguma alternativa para diminuir os efeitos prejudiciais ao Bradyrhizobium? Superando problemas nutricionais: como realizar a adubação com molibdênio e cobalto sem prejudicar a fixação biológica do N2? Adição de cobalto e molibdênio às sementes; E surgiram problemas pela aplicação de micronutrientes nas sementes? Quais as alternativas para compatibilizar o fornecimento de cobalto e molibdênio com a inoculação das sementes? Quando deve ser feita a inoculação no sulco? Como fazer o cálculo teórico do número de células de Bradyrhizobium no caso de inoculação no sulco? A capacidade de fixação do N2 da soja brasileira é superior à verificada em outros países?

Book Synopsis Biological Nitrogen Fixation by : Frans J. de Bruijn
Download or read book Biological Nitrogen Fixation written by Frans J. de Bruijn and published by John Wiley & Sons. This book was released on 2015-06-12 with total page 2250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is arguably the most important nutrient required by plants. However, the availability of nitrogen is limited in many soils and although the earth's atmosphere consists of 78.1% nitrogen gas (N2) plants are unable to use this form of nitrogen. To compensate , modern agriculture has been highly reliant on industrial nitrogen fertilizers to achieve maximum crop productivity. However, a great deal of fossil fuel is required for the production and delivery of nitrogen fertilizer. Moreover carbon dioxide (CO2) which is released during fossil fuel combustion contributes to the greenhouse effect and run off of nitrate leads to eutrophication of the waterways. Biological nitrogen fixation is an alternative to nitrogen fertilizer. It is carried out by prokaryotes using an enzyme complex called nitrogenase and results in atmospheric N2 being reduced into a form of nitrogen diazotrophic organisms and plants are able to use (ammonia). It is this process and its major players which will be discussed in this book. Biological Nitrogen Fixation is a comprehensive two volume work bringing together both review and original research articles on key topics in nitrogen fixation. Chapters across both volumes emphasize molecular techniques and advanced biochemical analysis approaches applicable to various aspects of biological nitrogen fixation. Volume 1 explores the chemistry and biochemistry of nitrogenases, nif gene regulation, the taxonomy, evolution, and genomics of nitrogen fixing organisms, as well as their physiology and metabolism. Volume 2 covers the symbiotic interaction of nitrogen fixing organisms with their host plants, including nodulation and symbiotic nitrogen fixation, plant and microbial "omics", cyanobacteria, diazotrophs and non-legumes, field studies and inoculum preparation, as well as nitrogen fixation and cereals. Covering the full breadth of current nitrogen fixation research and expanding it towards future advances in the field, Biological Nitrogen Fixation will be a one-stop reference for microbial ecologists and environmental microbiologists as well as plant and agricultural researchers working on crop sustainability.

Book Synopsis Plant Microbe Symbiosis: Fundamentals and Advances by : Naveen Kumar Arora
Download or read book Plant Microbe Symbiosis: Fundamentals and Advances written by Naveen Kumar Arora and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant microbe interaction is a complex relationship that can have various beneficial impacts on both the communities. An urgent need of today’s world is to get high crop yields in an ecofriendly manner. Utilization of beneficial and multifaceted plant growth promoting (PGP) microorganisms can solve the problem of getting enhanced yields without disturbing the ecosystem thus leading to sustainability. For this to achieve understanding of the intricate details of how the beneficial microbes form associations with the host plant and sustain that for millions of years must be known. A holistic approach is required wherein the diversity of microbes associated with plant and the network of mechanisms by which they benefit the host must be studied and utilized. ‘Plant Microbe Symbiosis – Fundamentals and Advances’ provides a comprehensive understanding of positive interactions that occur between plant and microorganisms and their utilization in the fields. The book reviews the enormous diversity of plant associated microbes, the dialog between plant-microbes-microbes and mechanisms of action of PGP microbes. Utilization of PGPRs as nutrient providers, in combating phytopathogens and ameliorating the stressed and polluted soils is also explained. Importantly, the book also throws light on the unanswered questions and future direction of research in the field. It illustrates how the basic knowledge can be amalgamated with advanced technology to design the future bioformulations.
Book Synopsis Strategies and Tools for a Sustainable Rural Rio de Janeiro by : Udo Nehren
Download or read book Strategies and Tools for a Sustainable Rural Rio de Janeiro written by Udo Nehren and published by Springer. This book was released on 2018-08-16 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of recent developments in land, ecosystem, and water management in the Brazilian state of Rio de Janeiro. The state is located in the biodiversity hotspot of the Atlantic Forest (Mata Atlântica), a biome characterized by high biological diversity and endemism. At the same time the state of Rio de Janeiro emerged to one of the economic hubs in Latin America. This development process has been accompanied by population growth, industrialization, urbanization, as well as consumption and degradation of land and water resources. In the past years many efforts have been made to stop or at least slow down these degradation processes and restore degraded environments with the overall goal to bring together sustainable management of natural resources, nature conservation, and economic development. An overview is provided of the different strategies and tools that have been developed in the fields of agriculture, ecosystem management and biodiversity, integrated water management, land restoration, disaster risk reduction and climate change adaptation, as well as environmental governance and economic instruments. This book covers a wide spectrum from applied research to science‐policy interfaces, planning concepts, and technical tools and has a model character for other rural areas in Latin America. Target groups are scientists, practitioners, policy makers and graduate students in the field of environmental management. The different chapters are written by researchers and practitioners of the German‐Brazilian project INTECRAL (Integrated Eco Technologies and Services for a Sustainable Rural Rio de Janeiro), the rural development program Rio Rural under the state secretary for agriculture and animal husbandry, as well as invited scientists from Brazilian universities and research institutes. It bridges existing gaps between science, policies, and practice in rural development.

Book Synopsis The Root Causes of Biodiversity Loss by : Alexander Wood
Download or read book The Root Causes of Biodiversity Loss written by Alexander Wood and published by Routledge. This book was released on 2013-11-05 with total page 416 pages. 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.
