Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the 2nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and with regard to current areas of investigation. The availability of several long-term studies allows a more in-depth approach to decomposition patterns and to the later stages of decomposition, as well as to humus formation and accumulation. The latest information focuses on three fields: - the effects of manganese on decomposition and possibly on carbon sequestration, - new findings on decomposition dynamics, and - the new analytical technique using 13C-NMR.

Download or read book Carbon Dioxide and Environmental Stress written by Luo Yiqi and published by Elsevier. This book was released on 1999-04-13 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the interactive effects of environmental stresses with plant and ecosystem functions, especially with respect to changes in the abundance of carbon dioxide. The interaction of stresses with elevated carbon dioxide are presented from the cellular through whole plant ecosystem level. The book carefully considers not only the responses of the above-ground portion of the plant, but also emphasizes the critical role of below-ground (rhizosphere) components (e.g., roots, microbes, soil) in determining the nature and magnitude of these interactions.* Will rising CO2 alter the importance of environmental stress in natural and agricultural ecosystems?* Will environmental stress on plants reduce their capacity to remove CO2 from the atmosphere?* Are some stresses more important than others as we concern ourselves with global change?* Can we develop predictive models useful for scientists and policy-makers?* Where should future research efforts be focused?

Download or read book Growing Plantation Forests written by P. W. West and published by Springer Science & Business Media. This book was released on 2013-10-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the scientific principles that are used throughout the world to ensure the rapid, healthy growth of forest plantations. As the population of the world increases so does the amount of wood people use. Large areas of natural forests are being cleared every year and converted to other uses. Almost as large an area of plantation forests is being established annually to replace those lost natural forests. Eventually, plantations will produce a large proportion of the wood used around the world for firewood, building, the manufacture of paper and bioenergy. Forest plantations can also provide various environmental benefits including carbon storage, rehabilitation of degraded land, serving as disposal sites for various forms of industrial or agricultural waste and enhancing biodiversity in regions that have been largely cleared for agriculture. Whatever their motivation, plantation forest growers want their plantations to be healthy and grow rapidly to achieve their purpose as soon as possible. This book discusses how this is done. It is written for a worldwide audience, from forestry professionals and scientists through to small plantation growers, and describes how plantations may be grown responsibly and profitably.

Download or read book Flower Seeds written by M. B. McDonald and published by Cabi. This book was released on 2005-01-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The floral industry represents a significant proportion of agricultural income in several developed countries, particularly the USA, the Netherlands and Japan. Hitherto, the sheer diversity of flower seeds, in their form, function and biology, has hindered the production of a comprehensive treatment of the topic. This book provides a unique and much-needed resource of information on the biology and technology of flower seeds. It presents in-depth information on the history and evolution of the ornamental and wild flower seed industries followed by recommendations for successful breed and production programs. A comprehensive coverage of the biology of flower seeds is considered as well as appropriate technologies associated with germination, vigor and viability testing. In this volume, the first of its kind, international authorities from academia and industry have been brought together to provide a comprehensive reference resource for both practitioners and students of seed science and technology and of ornamental horticulture.

Download or read book Plant Metal Interactions written by Sudhakar Srivastava and published by Springer. This book was released on 2019-07-26 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal toxicity and deficiency are both common abiotic problems faced by plants. While metal contamination around the world is a critical issue, the bioavailability of some essential metals like zinc (Zn) and selenium (Se) can be seriously low in other locations. The list of metals spread in high concentrations in soil, water and air includes several toxic as well as essential elements, such as arsenic (As), cadmium (Cd), chromium (Cr), aluminum (Al), and selenium (Se). The problems for some metals are geographically confined, while for others, they are widespread. For instance, arsenic is an important toxic metalloid whose contamination in Southeast Asia and other parts of world is well documented. Its threats to human health via food consumption have generated immense interest in understanding plants’ responses to arsenic stress. Metals constitute crucial components of key enzymes and proteins in plants. They are important for the proper growth and development of plants. In turn, plants serve as sources of essential elements for humans and animals. Studies of their physiological effects on plants metabolism have led to the identification of crucial genes and proteins controlling metal uptake and transport, as well as the sensing and signaling of metal stresses. Plant-Metal Interactions sheds light on the latest development and research in analytical biology with respect to plant physiology. More importantly, it showcases the positive and negative impacts of metals on crop plants growth and productivity.

Available in PDF, EPUB and Kindle. Book excerpt: Native woodlands occupy an important place in both our countryside and cultural heritage. They continue to provide timber and wood but nowadays are often equally valued as habitats for wildlife and areas for recreation. The aim of this handbook is to provide advice that will help managers understand their woodland and improve their management. A wide variety of subjects are included, from use of grazing animals, identification of woodland communities and management for nature conservation, to uneven aged silviculture, vegetation management and management planning. The background and principles of each topic are explained and case studies are used throughout. Interactions between inherent characteristics of the site and historic management are also considered in relation to future management options. The handbook also includes answers to questions that managers should be asking about their woodlands when different management styles are adopted depending on woodland ownership, location, objectives and characteristics
