Download or read book Handbook of Soil Sciences written by Pan Ming Huang and published by CRC Press. This book was released on 2011-11-17 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the atmosphere above, the biosphere within, and the geology below. It acts as an anchor for roots, a purveyor of water and nutrients, a residence for a vast community of microorganisms and animals, a sanitizer of the environment, and a source of raw materials for construction and manufacturing. To develop lasting solutions to the challenges of balanced use and stewardship of the Earth, we require a fundamental understanding of soil—from its elastic, porous three-phase system to its components, processes, and reactions. Handbook of Soil Sciences: Resource Management and Environmental Impacts, Second Edition is the second of two volumes that form a comprehensive reference on the discipline of soil science. Completely revised and updated to reflect the current state of knowledge, this volume covers interfacial interactions between the physical, chemical, and biological regimes within the soil; the factors that control the availability of plant nutrients and microelements; interdisciplinary aspects of soil science, including salinity, sodicity, and soil erosion; and soil databases for assessing worldwide soil resources. Critical elements addressed in each section include: Descriptions of concepts and theories Definitions, approaches, methodologies, and procedures Data in tabular and figure format Extensive references This cohesive handbook provides a thorough understanding of soil science principles and practices based on a rigorous, complete, and up-to-date treatment of the subject matter compiled by leading scientists. It is a resource rich in data, offering professional soil scientists, agronomists, engineers, ecologists, biologists, naturalists, and students their first point of entry into a particular aspect of the soil sciences.

Download or read book Nitrogen Management in Crop Production written by Nand Kumar Fageria and published by CRC Press. This book was released on 2014-06-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main approaches for safeguarding food security, sustainable development has increased demand for knowledge on fertilizer management in crop production. Among essential plant nutrients, nitrogen is one of the most important yield-limiting nutrients, mainly responsible for determining yield and yield components in cereals and legumes. It is also responsible for the activation of many enzymes and, of course, plays an important role in photosynthesis. With a recovery efficiency of less than 50 percent in most cropping systems, a large portion of the nitrogen applied as fertilizer is not used by plants, creating environmental and economic issues. Nitrogen Management in Crop Production covers the critical aspects for the judicious use of nitrogen in cropping systems. This includes appropriate methods of nitrogen application, effective source and timing of application during crop growth cycles, use of an adequate application rate to avoid loss and reduce cost, use of nitrogen-efficient crop genotypes, and use of legumes that fix sufficient amounts of atmospheric nitrogen. There is also a chapter on organic matter and its role in sustainability. This book presents recent information from the international literature, making it relevant for most agroecological regions. Chapters provide experimental results to aid in practical application of the information. The book contains color photos of nitrogen deficiency symptoms to serve as a guide for important crop species, such as rice, dry bean, wheat, soybean, and corn. It also includes numerous tables and figures, providing an easy-to-read reference.

This book was released on 2024-05-27 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horticultural crop production plays an important role in the global food supply, and horticultural plants contain numerous health-promoting phytochemicals, such as vitamins, flavonoids, polyphenols, and other secondary metabolites. The formation of yield and nutritional quality depends on the intrinsic characteristics of horticultural crops and environmental conditions. Light is the primary energy source for photosynthesis, and light, ranging from UV to far-red, is a critical factor in regulating plant growth, morphogenesis, development, and metabolic processes. The physiological and molecular regulation of plant processes is related to the intensity, spectrum, direction, photoperiod, and timing of light. And light is the most important environmental factor determining the yield and quality of horticultural crops.

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.

This book was released on 2012-12-06 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has been learned about the proper and judicious use of fertilizers. Fertilizer application by farmers has grown from an art to a science. As food producers have strived to increase crop yields by overcoming nutrient deficiencies the use of fertil izers has increased dramatically. This has created a large chemical industry capable of supplying the needed plant food elements. A more complete understanding of soil chemistry and plant nutrition has led to greater fertilizer use with improved fertilization methods and crop cultural practices. Improved fertilizer technology has led to the production of more efficient forms of fertilizer. The modem fertilizer industry and with it fertilization practices began in the humid countries of the world. The use of fertilizers in arid and semiarid regions was later in development, although agriculture had its beginning in semiarid and arid regions. The development offertilizer use is parallel to industrial development in various areas of the world.

Book excerpt: Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.
