Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.

Phosphorus (P) is an essential macronutrient for plant growth. It is as phosphate that plants take up P from the soil solution. Since little phosphate is available to plants in most soils, plants have evolved a range of mechanisms to acquire and use P efficiently – including the development of symbiotic relationships that help them access sources of phosphorus beyond the plant’s own range. At the same time, in agricultural systems, applications of inorganic phosphate fertilizers aimed at overcoming phosphate limitation are unsustainable and can cause pollution. This latest volume in Springer’s Plant Ecophysiology series takes an in-depth look at these diverse plant-phosphorus interactions in natural and agricultural environments, presenting a series of critical reviews on the current status of research. In particular, the book presents a wealth of information on the genetic and phenotypic variation in natural plant ecosystems adapted to low P availability, which could be of particular relevance to developing new crop varieties with enhanced abilities to grow under P-limiting conditions. The book provides a valuable reference material for graduates and research scientists working in the field of plant-phosphorus interactions, as well as for those working in plant breeding and sustainable agricultural development.

Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

Phosphorus is essential to the production of our food, and it also triggers algal blooms in lakes, rivers, and oceans when it slips through our hands. An understanding of this essential resource and how we have used and misused it over the years is crucial to the sustainability of our well-being on our planet. In this book, world authorities on phosphorus sustainability Jim Elser and Phil Haygarth explain this element's involvement in biology, human health and nutrition, food production, ecosystem function, and environmental sustainability. Phosphorus chronicles the sustainability challenges phosphorus both poses and solves in various contexts. The book begins with its discovery over 350 years ago, moving to its basic chemistry and the essential role it plays in all living things on Earth. Chapters go on to explain the rise in the usage of phosphorus in agriculture and how the increase in the mining of rock phosphate in the mid-20th century was essential for the Green Revolution. However, phosphorus emissions from human wastes and detergents triggered widespread algal blooms in the 1960s and 1970s. While such emissions have been brought under better control with wastewater treatment, diffuse emissions from farming continue to cause water quality degradation. The authors explain how these diffuse phosphorus emissions may worsen with climate change. In ten concise chapters, Elser and Haygarth offer engaging explanations of our historical use and abuse of phosphorus, including the phosphorus sustainability movement and new efforts to sustain food benefits of limited rock reserves following the phosphate rock price shock in 2007-2008. Highlighting new approaches for phosphorus, the two "Systems Innovators" turn toward the emerging set of sustainable phosphorus solutions necessary to achieve a sustainable "phosphoheaven" and avoid "phosphogeddon." The book provides an insider's take on this essential resource and why all of us need to wrestle with the wicked problems this element will cause, illuminate, or eliminate in years to come.

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.

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.

Phosphorus is an essential nutrient that occurs in almost all foods and is important for many normal physiological functions. In a typical Western diet, it is not harmful, but does adversely affect tissues in the body when consumed in excess or deficiency. This book provides a comprehensive review of various aspects of phosphorus in relation to human nutritional needs. Sections cover phosphorus nutrition and dietary issues; health risks associated with excess phosphorus intake that exceeds requirements; phosphorus intake in populations at risk; regulatory challenges and policy approaches; and environmental impacts of phosphates in the modern food supply. This book challenges the long held ideas that high dietary phosphorus intake beyond nutritional requirements is safe and the natural supply of phosphorus critical to agricultural and human food production is endless. Controversy surrounds the claim that largely unrestricted use of phosphorus in all aspects of food production from farm to fork increases dietary phosphorus intake and irretrievable environmental loss, both of which harm human and environmental health. The book editors have joined together experts in basic, medical, environmental, nutritional, and food science to explore the validity of these claims of harm from high intakes and the unchecked use of phosphorus in the global food supply. Despite the essential need for adequate phosphorus over all stages of plant, animal and human life, the growing evidence points to a worldwide increase in dietary phosphorus intake far beyond nutrient requirements, significant association with chronic disease risk even when renal function is not compromised, and the increase in environmental loss with crop run-off, animal husbandry, and unretrieved phosphorus from human waste. This current evidence alludes to a depleted, unsustainable natural supply of phosphorus, hazardous environmental pollution of lakes and waterways, and significant increases in the risk of kidney, skeletal, and other serious illnesses in humans in the future if action is not taken now.
