Download or read book Indicadores paraa tomada de decisão para a calagem no sistema de plantio direto written by M. Nicolodi and published by . This book was released on 2003 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: As recomendações de calagem utilizadas no sistema plantio direto (SPD) foram desenvolvidas no sistema convencional (SC), tendo como base o Ph do solo. No SPD ocorrem alterações nas características do solo, como dinamica diferenciada do alumínio e o aumento dos teores de Fósforo e Cálcio na cama superficial, que provocam uma menor resposta à calagem. A comissão de Química e Fertilidade si Solo NRS/SBCD alterou, em 2000, o valor do pH do solo de 6.0 para 5.5 e acrescentou a saturação por bases de 60% para a tomada de decisáo para a aplicaçõ de calc[ario so SPD. Há, ainda, a necessidade de sua validação em áreas de lavoura. O objetivo deste trabalho foi avaliar alguns indicadores para a tomada de decisão para a aplicaçào de calcário do SPD consolidado em Latossolo Vermelho distrófico, sem adição de tratamentos, onde foram coletadas amostras de solo e de tecido vegetal e avaliado o rendimento de grãos. Os coeficientes de determinação, entre o rendimento de grãos e os indicadores de acidez foram superiores com alumínio trocável, a saturação por alumínio de Al/Ca+Mg comparado ao pH em água e a saturção por bases, sendo estes os indicadores de tomada de decisão adotados pela Comissão ... a partir de 2000. Os valores de referencia de 0.3 cmol dm -3 de alumínio trocável ou 5% saturação por bases de 65, para a tomada de decisáo para a calagem no sistema de acidez e de fertilidade do solo não contribuiu para a melhora do processo de tomada de decisão.

Download or read book Proximal Soil Sensing written by Raphael A. Viscarra Rossel and published by Springer Science & Business Media. This book was released on 2010-07-25 with total page 440 pages. 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 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.

Download or read book The Biogas Handbook written by Arthur Wellinger and published by Elsevier. This book was released on 2013-02-19 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasing pressures to utilize wastes effectively and sustainably, biogas production represents one of the most important routes towards reaching renewable energy targets. This comprehensive reference on the development and deployment of biogas supply chains and technology reviews the role of biogas in the energy mix and outlines the range of biomass and waste resources for biogas production. Contributors provide detailed coverage of anaerobic digestion for the production of biogas and review the utilization of biogas for various applications. They consider all aspects in the biogas production chain from the origin of the biomass feedstocks, feedstock selection and preparation, the anaerobic digestion process, biogas plant equipment design and operation, through to utilization of the biogas for energy production and the residue, the digestate, which can be used as a biofertilizer. The book also addresses biogas utilization, and explores environmental impacts and commercial market applications.

Available in PDF, EPUB and Kindle. Book excerpt: [The book] strives to teach students that chemistry is relevant and interesting to us as individuals and to our understanding of the changing world around us. Chemistry can indeed be presented in a relevant fashion to those students for whom this may be their only science course. To that end, [the book] is sculpted to meet the needs of this specific group of students. The more matheamtical and theoretical aspects of chemistry are de-emphasized, and the more practical, or applied aspects are accentuated.-Pref.

Book excerpt: "The concept of grasslands as a global resource is not new. Indeed many recognised authorities have been canvassing for a global approach to understanding, managing and exploiting this resource for many years. This is the first book that gathers together leading experts from around the world to outline our current understanding of this complex ecosystem, the ways in which it can be enhanced and utilised and where the research challenges are for the future. The following themes unite the book: - Efficient production from grassland; - Grassland and the environment; - Delivering the benefits from grassland. The reader is given an in depth understanding of the biology of the system and how grasslands are crucial for soil stabilisation and water quality. Secondly, much attention is given to how grasslands offer the possibility of increasing food supply and income generation, which is a hugely important but often ignored facet in today's climate of extensification and biodiversity. Current advances in the grassland sciences have a proven potential to promote the economic development and environmental stability of regions, nations and peoples, particularly in some of the most resource-limited areas of the world. Approaches for achieving the most effective development and adoption of new technology are reviewed."
