VENTURA and published by . This book was released on 1987 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plantas de soja [Glycine max (L.) Merril], da variedade Parana, foram cultivadas em casa-de-vegetacao, empregando quartzo moido regado com solucao nutritiva, com o objetivo de se estudar os niveis de K, Ca, e Mg no substrato, bem como, os teores de nutrientes absorvidos e verificar as exigencias nutricionais atraves do acumulo de materia seca e da analise dos teores dos nutrientes em questao. O delineamento experimental foi um fatorial 3 expoente 3, estudando-se o K, Ca e Mg nas concentracoes de 117 - 234 - 351 ppm de K; 100 - 200 - 300 ppm de Ca e 24 - 48 e 72 ppm de Mg. A colheita foi efetuada sessenta e dois dias apos o plantio. As plantas foram separadas em: folhas superiores, folhas inferiores e caules e os teores de N, P, K, Ca, Mg, S, B, Fe, Mn e Zn foram determinados. Os resultados mostraram que: os tratamentos utilizados nao afetaram a altura das plantas e a massa de materia seca; o incremento na dose de K, Ca e Mg, aumentou a concentracao do elemento em questao, nas folhas superiores, inferiores e caules; o teor de Ca nas folhas superiores, nas folhas inferiores e no caule diminuiu com a elevacao das doses de K; o teor de Mg nas folhas superiores e no caule, decresceu com o aumento das doses de K; a elevacao das doses de Ca diminuiu o teor de Mg nas folhas superiores, inferiores e no caule; o acrescimo na dose K diminuiu as concentracoes de P, Ca, Mg, Mn e Zn nas folhas superiores, folhas inferiores e no caule; o acrescimo na dose Ca provocou diminuicao nas concentracoes de Mg e Mn, nas folhas superiores,

Book excerpt: The soybean [Glycine max (L. ) Merrill], a native of China, is one of the oldest crops of the Far East. For centuries, the Chinese and other Oriental people, including Japanese, Korean, and Southeast Asians, have used the bean in various forms as one of the most important sources of dietary protein and oil. For this reason and because the amount of protein produced by soybeans per unit area of land is higher than that of any other crop, this little old bean has been called "yellow jewel," "great treasure," "nature's miracle protein," and "meat of the field. " Now this bean is seen by some as a weapon against world hunger and a protein of the future. Most recently, the soybean has been touted as a possible weapon against chronic diseases. Since large-scale introduction to the Western world at the beginning of the twentieth century, the cultivation and use of soybeans have undergone a dramatic revolution: from traditional soyfoods in the Orient to a new generation of soyfoods in the West, from animal feed to value-added food protein ingredients, from industrial paints to affordable table oils and spreads, from an old field crop to a new crop with wide regions of adoptability, herbicide tolerance, pest resistance, and/or altered chemical composition, and from limited regional cultivation to expanded worldwide production.

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. Viscarra Rossel is a scientist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) of Australia. Alex McBratney is Pro-Dean and Professor of Soil Science in the Faculty of Agriculture Food & Natural Resources at the University of Sydney in Australia. Budiman Minasny is a Senior Research Fellow in the Faculty of Agriculture Food & Natural Resources at the University of Sydney in Australia.

Book excerpt: The palms are among the most abundant, diverse, and important families of plants found in the Amazon. Based on extensive field work, this book provides a systematic treatment of all palms that occur naturally in the Amazon region. Each species is exhaustively described with reviews of their distribution, habitat, and ecology. Introductory chapters describe the physical setting of the Amazon region as well as on the biogeography and ecology of the palm family. This first modern treatment of the 135 species of Amazon palms provides a definitive account of their ecology, uses, and biogeography. It will be welcomed by students, teachers, and researchers of botany, ecology, agronomy, and conservation biology.
