This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is an established fact that we must continually increase and improve agricultural production if we are to meet even the minimum requirements of a growing popu lation for food, shelter, and fuel. In recent years, the introduction of new plant varieties and the extensive use of fertilizers have effectively increased crop yields, but intensifying agricultural methods has often led to depleting soil fertility. Two examples of the harmful consequences of intensive farming practices are the loss of up to 2.5 cm of topsoil every 15 years in the United States through erosion and the alarming rise in environmental pollution through widespread use of pesticides. Countless other processes affecting the activity of soil micro flora and the inter actions between microorganisms and plants may pose an equal danger to soil equilibrium, but their potential hazards are often overlooked because of an insufficient understanding of soil microbiology on the part of scientists. In the first published study of its kind, the authors of this book have attempted to address major aspects of the microbial activity of soil in the tropics. Tropical conditions serve as an ideal context for a discussion of soil microbiology, since biological processes in the soil are particularly active in tropical environments in comparison to other settings and in relation to physical and chemical processes.

Download or read book Australian Vegetation written by R. H. Groves and published by Cambridge University Press. This book was released on 1994-07-21 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Australian vegetation has interested botanists and naturalists since Europeans first encountered Australia and its plant life. This 1994 edition of Australian Vegetation reviews the vegetation of the continent as a whole. In the introductory section, chapters on phytogeography, vegetation history and alien plants set the scene for further sections covering all the major vegetation types. The plant life of extreme Australian habitats is also discussed, and the book closes with a chapter on the conservation of Australian vegetation. Each chapter, written by experts on each particular habitat type, will inform and stimulate the interests of students and professional botanists, especially those fortunate enough to see for themselves the unique vegetation and flora of Australia.

Download or read book The Role Of Centrosema Desmodium And Stylosanthes In Improving Tropical Pastures written by Robert L Burt and published by CRC Press. This book was released on 2019-07-11 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This integrated collection describes the importance of forage legumes for pasture development and improvement in the tropics and subtropics. Leading agronomists review the magnitude of the need for pasture improvement; tropical and subtropical soil and climate environments; reports of the successful use of legumes in pasture development in a wet and a dry tropical environment; and the scope of the problem in terms of area to be developed and development logistics required. Three legume genera, Centrosema, Desmodium, and Stylosanthes, are discussed in detail--information is presented on taxonomy, adaptation, distribution, productivity, and usefulness--and considerable emphasis is placed on Rhizobium germplasm resources for these genera. A concluding section of technical essays addresses special considerations in using tropical legumes in pasture development and presents a coordinated multidisciplinary approach to legume exploration and evaluation.

Download or read book Modern Ecology written by G. Esser and published by Elsevier. This book was released on 2016-07-29 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on many case studies in the broad area of ecological studies and is derived from numerous sources originating from several countries. The book begins with discussions on morphology, stand structure, competition, mass and water balance at the stand level of vegetation as well as mineral cycles. A section deals with disturbances and management of agricultural as well as semi-natural systems. With the input of several authors, zoologists, botanists and geographers, detail is given to the eutrophication and pollution in terrestrial ecosystems. Included as well are discussions on the carbon cycle as it relates to current climate change and modern methods of remote sensing and geographical modelling. The book concludes with a chapter on urban and landscape ecology. The main feature of this book is that it includes most methods and tasks of modern ecology using case studies and incorporating all levels of integration from single plants and animals to populations and ecosystems.
