Download or read book The Ecology of Tropical East Asia written by Richard T. Corlett and published by Oxford University Press. This book was released on 2019-06-27 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical East Asia is home to over one billion people and faces massive human impacts from its rising population and rapid economic growth. It has already lost more than half of its forest cover to agriculture and urbanization, and has the highest rates of deforestation and logging in the tropics. Habitat loss, coupled with hunting and the relentless trade in wildlife products, threatens all its large and many of its smaller vertebrates. Despite these problems, the region still supports an estimated 15-25% of global terrestrial biodiversity and a growing environmental awareness means that it is no longer assumed that economic development justifies environmental damage, and no longer accepted that this trade-off is inevitable. Effective conservation action now depends on integrating a clear understanding of the ecological patterns and processes in the region with the varied needs of its human population. This third edition continues to provide an overview of the terrestrial ecology of Tropical East Asia: from southern China to Indonesia, and from Bhutan and Bangladesh to the Ryukyu Islands of Japan. It retains the balance between compactness and comprehensiveness of the previous editions, and the even-handed geographical treatment of the whole region, but it updates both the contents and the perspective. Approximately one third of the text is new or greatly modified, reflecting the explosion of new research in the region in the last few years and the increasing use of new tools, particularly from genomics and remote sensing. The change in perspective largely reflects the growing realization that we are in a new epoch, the Anthropocene, in which human activities have at least as large an influence as natural processes, and that stopping or reversing ecological change is no longer an option. This does not mean that biodiversity conservation is no longer possible or worthwhile, but that the biodiverse future we strive for will inevitably be very different from the past. The Ecology of Tropical East Asia is an advanced textbook suitable for senior undergraduate and graduate level students taking courses on the terrestrial ecology of the East Asian tropics, as well as an authoritative regional reference for professional ecologists, conservationists, and interested amateurs worldwide.
Download or read book Soils Crops and Fertilizer Use written by David K. Leonard and published by . This book was released on 1981 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture extension work requires more than good intentions and rapport with farmers. The real challenge is usually establishing credibility in the agriculture skills area. Agriculture at the small farmer level in a developing country is a complex endeavor. Farmers have much they can teach you when it comes to land preparation, planting, harvesting, using tools, and other manual skills. Likewise, there are many yield boosting skills you can show them, especially in the areas of soil conservation, organic and chemical fertilizer use, and the safe and appropriate use of agricultural chemicals. This manual has been designed as an on-the-job reference for soil management and fertilizer use; hopefully, it will help along that sometimes bumpy road to credibility.

Download or read book Soil Fertility written by Boyd Ellis and published by CRC Press. This book was released on 2018-05-04 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are one of the world's most important resources, and their protection, maintenance, and improvement is critical to the continuance of life on earth. Soil Fertility, Second Edition, offers thorough coverage of the fertility, composition, properties, and management of soils. This book carries on the tradition of excellence established by authors Henry Foth and Boyd Ellis, leading soil scientists whose previous books in this field have become multi-edition classics. The Second Edition of Soil Fertility has been significantly expanded to include more information on mineralogy, while keeping the thorough coverage of essential topics. The book presents soils as dynamic, constantly changing bodies, and relates soil fertility and management to the mineralogy of their origin. Four new chapters offer updated information on soil charge properties, ion adsorption, exchange and fixation, and soil reaction. There is also a far greater emphasis on environmental issues, reflecting the increasing importance of environmental concerns to agronomists and soil scientists today.

Download or read book Phosphorus Along the Soil Freshwater Ocean Continuum written by Barbara J. Cade-Menun and published by Frontiers Media SA. This book was released on 2019-05-15 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential element for all organisms. However, there is a P paradox, whereby P concentrations considered deficient in some environments such as in agricultural soils are considered excessive in water, where they trigger eutrophication. Ensuring adequate P for crop production while minimizing water quality degradation requires consideration of the P continuum from soils to freshwater and oceans. It also requires an international, interdisciplinary approach to monitoring and scientific research. This eBook brings together P studies in soil science, lakes, rivers, estuaries and oceans, with 74 authors from 12 countries in Asia, Europe and North America. The papers assembled here provide important new information to address knowledge gaps, cover P forms and cycling in soil and water, and identify key priorities for future research. Thus, the papers assembled here provide current and interdisciplinary information about P forms and their cycling along the soil-freshwater-ocean continuum, which is essential for environmentally sustainable P use.
Download or read book Soil Management written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.
