Available in PDF, EPUB and Kindle. Book excerpt: The world population is projected to reach nine billion by 2050, and in the coming years, global food demand is expected to increase by 50% or more. Higher crop productivity gains in the future will have to be achieved in developing countries through better natural resources management and crop improvement. After nitrogen, phosphorus (P) has more widespread influence on both natural and agricultural ecosystems than any other essential plant element. It has been estimated that 5.7 billion hectares of land worldwide contain insufficient amounts of available P for sustainable crop production, and P deficiency in crop plants is a widespread problem in various parts of the world. However, it has been estimated that worldwide minable P could last less than 40 years. For sustaining future food supplies, it is vital to enhance plant P use efficiency. To bring the latest knowledge and research advances in efficient management of P for economically viable and environmentally beneficial crop production in sustainable agriculture, Phosphorus Management in Crop Production contains chapters covering functions and diagnostic techniques for P requirements in crop plants, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, and basic principles and methodology regarding P nutrition in crop plants. The majority of research data included are derived from many years of field, greenhouse, and lab work, hence the information is practical in nature and will have a significant impact on efficient management of P-fertilizers to enhance P use efficiency, improve crop production, promote sustainable agriculture, and reduce P losses through eluviations, leaching, and erosion to minimize environmental degradation. A comprehensive book that combines practical and applied information, Phosphorus Management in Crop Production is an excellent reference for students, professors, agricultural research scientists, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.

Download or read book Phosphorus in Agriculture 100 Zero written by Ewald Schnug and published by Springer. This book was released on 2016-06-14 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The title ‘Phosphorus in Agriculture: 100 % Zero’ is synonymous for make-or-break. And it stands up to the promise. This book sends an important message as it delivers background information, intrinsic hypotheses, validation approaches and legal frameworks, all for balanced phosphorus fertilization in agriculture. This implies firstly that the phosphorus requirement of crop is fully satisfied by applying exclusively fertilizers which contain the nutrient in completely available form. Secondly, environmental demands through eutrophication and hazardous contaminants must not be compromised. The book identifies equally knowledge gaps and deficits in the transformation and implementation of research into practice. Bottom line is that research delivers the tools for a sustainable phosphorus management while legal frameworks are insufficient.

Download or read book Phosphorus Recovery and Recycling written by Hisao Ohtake and published by Springer. This book was released on 2018-05-25 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the engineering aspects of phosphorus (P) recovery and recycling, presenting recent research advances and applications of technologies in this important and challenging area of engineering. It highlights full-scale applications to illustrate the performance and effectiveness of the new technologies. As an essential element for all living organisms, P cannot be replaced by any other element in biochemical processes, humans ultimately rely its availability. Today, P is mostly obtained from mined rock phosphate (Pi). However, natural reserves of high-grade rock Pi are limited and dwindling on a global scale. As such, there have been increased efforts to recycle P from secondary sources, including sewage sludge, animal manure, food waste, and steelmaking slag, and so close the anthropogenic P cycle. In addition to various aspects of phosphorus covered by other literature, including chemistry, biochemistry, ecology, soil-plant systems and sustainable management, this book is a valuable and comprehensive source of information on the rapidly evolving field of P recovery and recycling engineering for students, researchers, and professionals responsible for sustainable use of phosphorus.

This book was released on 2008 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient use of phosphorus (P) is essential to many agricultural and environmental issues. This bulletin reviews, analyses and synthesizes information on the efficient use of soil and fertilizer P. It presents information on the plant availability of soil and fertilizer P, with an emphasis on soil plant interactions. The focus is on the changing concepts of the behaviour of both soil and fertilizer P and on the need to define and assess their recovery and, thus, P-use efficiency more appropriately.

Book excerpt: Sustainable crop production aims at maintaining high crop yield without adversely affecting ecosystems to meet the need of current as well as future generations. In order to meet the increasing world population agricultural production and productivity need to parallel increased. Since phosphorus (P) in agriculture is the second most growth limiting macronutrient after nitrogen, its proper management in soil contributes significantly to sustainable crop production. Despite its importance for normal plant growth and metabolism, P is one of the least accessible nutrients. Phosphorus is a macronutrient that plays a number of important roles in plants, and is fundamental for the efficient use of nitrogen fertilizer. The maximum uptake rate of phosphorus by plants occurs around flowering but its accumulation continues until maturity. Adequate phosphorus results in higher grain production, improved crop quality, greater stalk strength, increased root growth, and earlier crop maturity. For over one hundred years, phosphorus has been applied to crops as fertilizer-first as ground bone and now as some chemical reaction product of ground rock. Yet, for all that experience, its management cannot be taken for granted.Phosphorus Management in Crop Production presents in-depth coverage of soil and climatic factors that affect P availability and diagnostic techniques for P requirements by different crops as well as provide up-to-date information on the function of P in crop plants and methods to identify P use efficient field crops practices that could enhance P use efficiency.Definitive chapters cover sustainable phosphorus management in agriculture, soil order and management practices control soil phosphorus fractions, does balanced phosphorus fertilization sustain high herbage yields and phosphorus contents in alternately grazed and mown pastures, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, phosphorus cycling in Montreal's food and urban agriculture systems and basic principles and methodology regarding P nutrition in crop plants. This work is a comprehensive guide for students, lecturers, practitioners, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.
