Download or read book Manejo de Pastos y Forrajes Tropicales written by Ali Perozo and published by Ali David Perozo Bravo. This book was released on 2013-11-28 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: La alimentación de los rebaños en el trópico se fundamenta en el uso de pastos y forrajes, los cuales constituyen la dieta básica y más económica en la alimentación de rumiantes (bovinos, bufalinos, caprinos y ovinos). Sin embargo, la producción de materia seca de los pastos y forrajes a través del año es irregular en cantidad y calidad debido a limitaciones climáticas y edáficas. Los pastos son importantes en principio porque pueden crecer en condiciones marginales donde otros cultivos no pueden, lo cual se atribuye a su mayor eficiencia en el uso del agua y a un máximo aprovechamiento de los nutrientes del suelo; además, los pastos proporcionan materia orgánica al suelo, lo que ayuda en su conservación. Existe toda una gama de estrategias que pueden utilizarse para iniciar y mejorar el cultivo de las tierras, la cuales serán detalladas a lo largo del contenido del Cuaderno Científico 13 editado por la Fundación Girarz. La difusión de este Cuaderno se realizó en la LXIII Reunión dedicada al “Curso de Manejo de Pastos y Forrajes Tropicales” en celebración del XXXV Aniversario de la Fundación GIRARZ y como homenaje al 54 Aniversario de la creación de la Facultad de Agronomía de la Universidad del Zulia, en el estado Zulia

Download or read book Alternative Farming Systems Biotechnology Drought Stress and Ecological Fertilisation written by Eric Lichtfouse and published by Springer Science & Business Media. This book was released on 2011-01-19 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for our children. This discipline addresses current issues such as climate change, increasing food and fuel prices, starvation, obesity, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. Novel solutions are proposed based on integrated knowledge from agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, philosophy and social sciences. As actual society issues are now intertwined, sustainable agriculture will bring solutions to build a safer world. This book series analyzes current agricultural issues, and proposes alternative solutions, consequently helping all scientists, decision-makers, professors, farmers and politicians wishing to build safe agriculture, energy and food systems for future generations.

Download or read book Tropical Deforestation written by Thomas K. Rudel and published by Columbia University Press. This book was released on 1993 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The highly publicized obscenity trial of Radclyffe Hall's The Well of Loneliness (1928) is generally recognized as the crystallizing moment in the construction of a visible modern English lesbian culture, marking a great divide between innocence and deviance, private and public, New Woman and Modern Lesbian. Yet despite unreserved agreement on the importance of this cultural moment, previous studies often reductively distort our reading of the formation of early twentieth-century lesbian identity, either by neglecting to examine in detail the developments leading up to the ban or by framing events in too broad a context against other cultural phenomena. Fashioning Sapphism locates the novelist Radclyffe Hall and other prominent lesbians--including the pioneer in women's policing, Mary Allen, the artist Gluck, and the writer Bryher--within English modernity through the multiple sites of law, sexology, fashion, and literary and visual representation, thus tracing the emergence of a modern English lesbian subculture in the first two decades of the twentieth century. Drawing on extensive new archival research, the book interrogates anew a range of myths long accepted without question (and still in circulation) concerning, to cite only a few, the extent of homophobia in the 1920s, the strategic deployment of sexology against sexual minorities, and the rigidity of certain cultural codes to denote lesbianism in public culture.

Available in PDF, EPUB and Kindle. Book excerpt: This introductory text explains the fundamentals of the chemistry of the natural environment and the effects of mankind's activities on the earth's chemical systems. Retains an emphasis on describing how natural geochemical processes operate over a variety of scales in time and space, and how the effects of human perturbation can be measured. Topics range from familiar global issues such as atmospheric pollution and its effect on global warming and ozone destruction, to microbiological processes that cause pollution of drinking water deltas. Contains sections and information boxes that explain the basic chemistry underpinning the subject covered. Each chapter contains a list of further reading on the subject area. Updated case studies. No prior chemistry knowledge required. Suitable for introductory level courses.

Available in PDF, EPUB and Kindle. Book excerpt: Artificial drainage is essential to sustain irrigated agriculture, in order to control the water table and avoid waterlogging and salinisation. Biodrainage systems rely on vegetation rather than mechanical means to remove excess water, and can provide a cost-effective and environmentally friendly drainage option. This publication presents a range of formally published and unpublished literature on the current level of knowledge of biodrainage, in order to inform further research and promote pilot testing schemes.

Download or read book Grassland written by D. A. McGilloway and published by Brill Wageningen Academic. This book was released on 2005 with total page 438 pages. Available in PDF, EPUB and Kindle. 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."
