Book excerpt: A agricultura de precisão é uma técnica baseada na coleta de informações georreferenciadas de solo, folha e produção, a fim de subsidiar a aplicação de fertilizantes a taxas variáveis e aperfeiçoar o manejo da adubação. O objetivo deste trabalho foi diagnosticar de forma especializada o estado nutricional da cultura da soja em uma área de produção comercial, a partir de dados de análises foliares georreferenciadas e identificar os fatores nutricionais interferentes na produtividade. Foi selecionado um talhão de 107 hectares, localizado em Planaltina de Goiás - GO, dividido em uma grade regular de 100 x 100m. No florescimento de soja, foram coletadas para análise foliar amostras compostas para cada quadrícula. O monitoramento da produção foi feito por meio de uma colheitadora equipada com GPS e sensores de produtividade. Os resultados das análises foliares para cada nutriente foram interpretados pelo método das faixas de suficiência e pelo Sistema integrado de diagnose e Recomendação - DRIS. Foram ainda determinadas faixas de suficiência especificadas para a área de estudo, ajustada pelo DRIS. O N foi o nutriente mais limitante, de acordo com os valores recomendados pela literatura, enquanto os índices DRIS apontaram maiores relacionamentos a N, Cu e P. Quando considerada a faixa de suficiência ajustada pelo DRIS, foram evidenciadas maiores limitações relacionadas a Cu, B, N, Mn e Zn. A partir da diferença entre teores foliares simulados e teores foliares analisados, obteve-se o diagnóstico especializado para cada nutriente, indicando subáreas de maior probabilidade de resposta a medidas corretivas dentro do talhão, o que permite o estabelecimento de zonas de manejo específico, resultando no uso mais econômico e racional de fertilizantes. Palavras - chave: agricultura de precisão, análises foliares, DRIS.

Book excerpt: RESUMO: Neste trabalho, objetivou-se identificar os fatores relacionados à produtividade da soja, utilizando informações georreferenciadas sobre o estado nutricional das plantas, atributos do solo e produtividade da cultura. Uma área de 27,5 hectares foi dividida em grade amostral regular de 50 x 50m para coletas de folhas e do solo para análise. A colheita foi monitorada por meio de uma colhedora equipada com sensor de produtividade e DGPS. Os resultados das análises de solo e de folhas foram interpretados agronomicamente e correlacionados entre si e com a produtividade. Foram gerados mapas representando a espacialização das variáveis mais relevantes. Não foram obtidas correlações significativas dos teores foliares de nutrientes com as características do solo ou com a produtividade. Na lavoura estudada, os teores da matéria orgânica e potássio no solo e a saturação do potássio na CTC são os atributos mais relacionados com a produtividade da soja. ABSTRACT: The aim of this study was to identify yield conditioning factors of a soybean crop, based on georreferenced information concerning the plant nutritional status, soil attributes, and crop yield. An area of 27,5 ha was divided in a regular grid of 50 x 50m for colecting leaf and soil samples. The harvest was done using yield monitor and DGPS. Soil, plant, and yield data were interpreted on the agronomic basis, and submitted to correalation analysis. The spatial variation of the most important variables was mapped. It was not found any significant correlation among leaf nutrient concentrations and soil characteristics or yield. The soil organic matter and potassium contents, as well as the CEC potassium saturation, were the variables most correlated with the soybean yield.

Available in PDF, EPUB and Kindle. Book excerpt: A expressão do potencial de desenvolvimento e de rendimento de uma planta depende, dentre os fatores de produção, do ambiente, de adequada disponibilidade de nutrientes em quantidade e no momento que for necessário. Caso o solo não forneça quantidade suficiente dos mesmos, faz-se necessária a aplicação dos nutrientes em deficiência de forma a suplementar o fornecimento do solo. A quantidade de nutrientes a ser fornecida baseia-se no conhecimento das necessidades nutricionais da cultura e na capacidade de fornecimento desses pelo solo. A análise química do solo é a ferramenta mais utilizada para diagnóstico e recomendação de intervenção no processo de produção, como a aplicação de corretivos da acidez do solo e de fertilizantes. Com o objetivo de avaliar o estado nutricional de soja no Sul de Mato Grosso do Sul, 87 amostras de solo e grãos foram coletadas nas entrelinhas de lavouras comerciais, da variedade CD 202, na safra 2000/01, durante os estádios V a V , nas 1 4 profundidades 0-20 e 20-40 cm. Os resultados mostraram que: a) os nutrientes da mais limitantes foram Zn, K e P, respectivamente em 18,5, 12,6 e 10,3 % das lavouras amostradas; e b) concentrações elevadas de Al e baixas de Ca, nas camadas subsuperficiais do solo, foram limitações químicas em 16% das lavouras amostradas.

This book was released on 2008-05-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to help identify major gaps in our knowledge of how gender and age affect psychiatric diagnoses and to stimulate much-needed research to fill these gaps, Age and Gender Considerations in Psychiatric Diagnosis serves as both a valuable short-term source for the DSM-V Task Force and its disorder-specific workgroups, and a long-term guide for future studies that will contribute to revised psychiatric classifications in these three areas. Here, 47 experts present findings in three areas of psychiatric research that historically have been neglected but rightfully have received increasing attention in recent years and thus are worthy of investigation into their clinical features, etiology, and course: 1. Significant gender differences in prevalence, symptom profiles, and risk factors for mental disorders, including neurodevelopmental, neurophysiological, and environmental factors for men and women that cut across diagnostic categories-for example, the critical importance of gender in how psychiatric illness develops and presents; DSM's approach to gender to date; and relevant research findings and gaps in the epidemiology, etiology, and pathophysiology of disorders and the gender-related expression of psychopathology, including the controversial and complex question of whether DSM should have different diagnostic criteria for men and women. 2. Mental disorders in infancy and early childhood, including diagnosis and measurement of psychopathology; PTSD and social and cognitive factors related to the experience of stress; reactive attachment disorder (unique in part because of its specificity to early childhood); mood and anxiety disorders and difficulties in diagnosis; sleep disorders, including two new disorders, Night-Waking Dysomnia and Sleep-Onset Dysomnia; feeding disorders, including the need to address overeating and overfeeding (especially given the alleged U.S. epidemic of obesity); early childhood manifestations of behavior disorders; and early symptoms and diagnosis of autism. 3. Mental disorders in the elderly, such as dementia and depression, once considered normal consequences of aging but now understood to represent mental disorders, including the need to identify specific brain structure abnormalities, biomarkers, and the many contributing biological, psychosocial, and environmental factors of mental illness in late life and to understand their roles in the elderly to better diagnose and monitor disease progression. Written for clinicians and researchers alike, this thought-provoking compendium contributes critical information that helps enhance our understanding of the causes of mental disorders, develop effective preventive and treatment interventions, and inform future editions of DSM and ICD.

Book excerpt: Descended from a long and ancient lineage, tapirs are important tropical forest seed dispersers. However, today, all species of tapirs are threatened to various degrees by habitat destruction and hunting. This action plan was written with wildlife biologists, ecologists, administrators, educators and local conservation officials in mind and is aimed at those countries with tapir populations. It provides a brief natural history of each species and its objective is to aid in their conservation by catalyzing conservation action. In addition, it is hoped that the contents of the plan will stimulate further research into this fascinating group of animals.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of a new series which will present the proceedings of the newly established Nestlé Nutrition Workshop Series: Clinical & Performance Programme aimed at adult nutrition. Undernutrition is a common phenomenon in elderly people, and malnutrition reaches significant levels in those being in hospital, nursing homes or home care programs. Consequences of malnutrition often go unrecognised owing to the lack of specific validated instruments to assess nutritional status in frail elderly persons. The Mini Nutritional Assessment (MNA) provides a single, rapid assessment of nutritional status in the elderly of different degrees of independence, allowing the prevalence of protein-energy malnutrition to be determined and to evaluate the efficacy of nutritional intervention and strategies. Easy, quick and economical to perform, it enables staff to check the nutritional status of elderly people when they enter hospitals or institutions and to monitor changes occurring during their stay. Moreover, the MNA is predictive of the cost of care and length of stay in hospital. This publication will be of immense assistance to heads of geriatric teaching units, teachers in nutrition, clinicians general practitioners and dieticians, enabling them to better detect, recognise and start treatment of malnutrition in the elderly.

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.

Book excerpt: The book is based on the exchange of professional experiences which featured in an IUCN CEC workshop in August 2002. Practitioners from around the world shared their models of good practice and explored the challenges involved in engaging people in sustainability. The difficulties facing practitioners vary between country and context but some challenges are universal: A lack of clarity in communicating what is meant by sustainable development; An ambition to educate everyone to bring about a global citizenship; Social, organisational or institutional factors constrain change to sustainable development, yet there is an emphasis on formal education, and community educators do not receive the same support; A lack of balance in addressing the integration of environmental, social and economic dimensions leading to an interpretation that ESD is mainly about environment and conservation issues; New learning (rather than teaching) approaches are called for to promote more debate in society. Yet, few are trained or experienced in these new approaches. Practitioners need support to explore new ways of promoting learning. [Foreword, ed].

Available in PDF, EPUB and Kindle. Book excerpt: When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.
