This book was released on 1972 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Realizaram-se experimentos de campo sobre niveis de fosforo e calagem com amendoim e com o feijao apos crotalaria e sobre efeito residual da adubacao na cultura do arroz, em conco localidades. Houve efeito linear do fosforo em dois experimentos com amendoim e em um com feijao. Nos experimentos de efeito residual com arroz houve efeito linear do fosforo em dois e efeito linear do calcario e da interacao fosforo-calcario em um. Apesar da estiagem prolongada, foram alcancadas producoes razoaveis (amendoim 1,5 vezes, feijao 1,9 vezes e arroz 2,3 vezes as producoes medias do Brasil em 1969, respectivamente). Calcularam-se o lucro e a relacao entre o valor do aumento da producao e o custo dos tratamentos (adubo e corretivo), havendo compensacoa em tres das cincolocalidades.

This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Por ser fosforo, de um modo geal, o nutriente de plantas limitante em solos sob vegetacao de cerrado efetuou-se o presente trabalho para investigar esse fatoe comparar os efeitos de tres fontes de fosforo, em quatro doses na producao de graos de soja cultivar UFV-1, em um solo sob vegetacao de cerrado, classificado como Latossolo Vermelho-Escuro alico, textura argilosa, da Fazenda Experimental da UNESP - Campus de Ilha Solteira, municipio de Selviria, MS. No ano agricola 1978/79 (1o cultivo) os tratamentos foram instalados a partir de tres fontes fosfatadas (superfosfato triplo, termofosfato Mg-Yoorin e fosfato de Araxa) e quatro niveis (considerando-se os fatores 0,5 - 1,0 - 1,5 - 2,0 vezes o valor X, calculado pelo processo de WAUGH e FITTS, modificado por FERREIRA, aplicados a lanco e incorporados a uma profundidade de 0-20 cm. No ano agricula 1979/80 (2o cultivo) os tratamentos foram formados pelos tratamentos do primeiro cultivo (efeito residual) mais cinco niveis de adubacao fosfatada (soperfosfato triplo) em manutencao no sulco de plantio. Para avaliacao, realizou-se amostragem de solo em diferentes periodos (outubro e novembro de 1978; marco e novembro de 1979; marco de 1980) determinando-se pH, Al+3 trocavel, Ca++ + Mg++ trocaveis e P soluvel em NH4F 0,03N + Hcl 0,025N (Bray-1) e producao de graos no ano agricola de 1978/79 e ano agricola de 1979/80.

Download or read book Plant-Soil Interactions at Low pH written by Robert J. Wright and published by Springer. This book was released on 2012-12-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

Available in PDF, EPUB and Kindle. Book excerpt: Completely updated and revised, this bestselling book continues to explain the growth and developmental processes involved in the formation of vegetables. Since the publication of the successful first edition significant discoveries, particularly in the area of molecular biology, have deepened and broadened our knowledge and understanding of these processes. This new edition brings the topic up-to-date and is presented over two sections: the first provides general knowledge on germination, transplanting, flowering, the effects of stress and modelling, whilst the second section details the physiology of specific crops or crop groups.

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. 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.
