This book was released on 1999 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conduziram-se seis experimentos de campo no municipio de Cristalina-GO, no ano agricola 1996/1997, para avaliar o efeito de residuo de herbicidas, aplicados na cultura da soja, sobre culturas em sucessao nos sistemas de plantio convencional e direto. Os ensaios foram instalados em latossolo vermelho-amarelo contendo 510 a 560 g/kg de argila e 28 e 29 g/kg de materia organica. Os hebicidas utilizados em pos-emergencia foram o fomesafen (250 g/ha) e o chlorimuron-ethyl (20 g/ha), no delineamento experimental de blocos casualizados com quatro repeticoes. Os produtos foram aplicados com pulverizador costal de propulsao a CO2 e volume de calda de 100 l/ha. Apos a colheita da soja, ha 80 dias apos aplicacao dos herbicidas, milho, sorgo e milheto foram semeados no mesmo delineamento experimental. Avaliou-se a fitoxicidade aos 10 e 30 dias apos a emergencia, altura de planta na colheita, estande final e produtividade. Amostras de solo foram coletadas aos 0, 7, 15, 30, 60, 90, 120 e 150 dias apos a aplicacao dos herbicidas e utilizadas para bioensaio em casa de vegetacao. Avaliou-se a porcentagem de reducao, com relacao a testemunha, da materia seca total de plantas de nabo utilizado com planta teste. A precipitacao pluviometrica entre a aplicacao dos herbicidas e a semeadura das culturas em sucessao foi de 464 mm. O residuo de fomesafen no solo causou toxicidade as culturas do milho e sorgo somente no plantio convencional, reduzindo a produtividade apenas do sorgo. O residuo de chlorimuron-ethyl no solo causou toxicidade as tres culturas, no plantio convencional e direto, reduzindo a produtividade somente do sorgo, em ambos os sistemas de cultivo. A degradacao do chlorimuron-ethyl no solo, ocorreu de forma semelhante no plantio convencional e direto, apresentando uma persistencia em torno de 90 dias. As culturas do milho e milheto mostraram-se pouco sensiveis aos residuos de ambos herbicidas nos dois sistemas de cultivo. O nabo utilizado nao se mostrou um indicador biologico eficiente para deteccao de residuo de fomesafen no solo.

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.

Book Synopsis Proximal Soil Sensing by : Raphael A. Viscarra Rossel
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 Synopsis Soil Quality for Crop Production and Ecosystem Health by : E.G. Gregorich
Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Book Synopsis Intellectual Property Overlaps by : Estelle Derclaye
Download or read book Intellectual Property Overlaps written by Estelle Derclaye and published by Bloomsbury Publishing. This book was released on 2011-05-11 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intellectual property rights, conventionally seen as quite distinct, are increasingly overlapping with one another. There are several reasons for this: the expansion of IPRs beyond their traditional borders, the creation of new IPRs especially at EU level, the exploitation of gaps in the law by shrewd lawyers, and the use of unfair competition as an alternative when IPRs are either not available at all or expired. The convergence of several IPRs on the same subject-matter poses problems. As they are normally envisaged as water-tight categories, there are very few rules which cater for the sort of regime clash that any overlap of IPRs necessarily entails. This book's aim is to find appropriate rules to regulate overlaps and thereby avoid regime conflicts and undue unstructured expansion of IPRs. The book studies the practical consequences of each overlap at the international, European and national levels (where the laws of France, the UK and Germany are reviewed). It then analyses the reasons for the prohibition or authorisation of overlaps. This analysis enables the determination of criteria and principles that can be used to (re)map the overlaps to achieve appropriateness and legitimacy.
