Download or read book Soil Phosphorus written by Rattan Lal and published by CRC Press. This book was released on 2016-09-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Phosphorus in Action by : Else K. Bünemann
Download or read book Phosphorus in Action written by Else K. Bünemann and published by Springer Science & Business Media. This book was released on 2010-11-08 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Inositol Phosphates by : Benjamin L. Turner
Download or read book Inositol Phosphates written by Benjamin L. Turner and published by CABI. This book was released on 2007 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inositol phosphates are a group of organic compounds found widely in the natural environment. They are important in agriculture because they constitute most of the phosphorus in grain seeds, but they cannot be digested by some animals. As a result, considerable research has been directed towards improving the digestibility of inositol phosphates in animal diets. Inositol phosphates are also abundant in soils and water bodies, yet a clear understanding of their behaviour in the environment remains elusive. This is surprising given the importance of phosphorus in the nutrition of both terrestrial and aquatic ecosystems. Written by leading experts, this book brings together critical reviews on inositol phosphates in agriculture, ecology, and the environment. The sixteen chapters cover a diverse range of topics, including the synthesis and hydrolysis of inositol phosphates, their role in animal nutrition, and their fate in soils and aquatic ecosystems. It will prove valuable to a wide readership in the agricultural and biological sciences, and will serve as a unique reference source on this emerging topic.
Book Synopsis Organic Phosphorus in the Environment by : Benjamin L. Turner
Download or read book Organic Phosphorus in the Environment written by Benjamin L. Turner and published by Cabi. This book was released on 2005 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus is essential for life, yet is often the element most limiting for biological productivity. Although most organisms take up phosphorus in an inorganic form, organic forms frequently dominate in soils and aquatic systems. Up to this point, the role of organic phosphorus and mechanisms for its dynamics have been poorly understood. However, recent advances in research have shed new light on the subject and this book brings together these advances. It covers the transformation and characterization of organic phosphorus in both terrestrial and aquatic systems. It will attract a broad range of scientists from several disciplines.

Book Synopsis The Ecophysiology of Plant-Phosphorus Interactions by : Philip J. White
Download or read book The Ecophysiology of Plant-Phosphorus Interactions written by Philip J. White and published by Springer Science & Business Media. This book was released on 2008-06-03 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis The Role of Organic Matter in Modern Agriculture by : Y. Chen
Download or read book The Role of Organic Matter in Modern Agriculture written by Y. Chen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of organic residues as a means of maintaining and increasing soil fertility is of long-standing. This tradition has been somewhat neglected since the introduc tion of mineral fertilizers at low cost. More and more farmers and scientists are now showing renewed interest in the proper and effective use of org~tnic residues, composts and other recycled organic additives. The role and function of organic amendments in modern agricultural systems have become topics of major interest in the scientific and agricultural communities. Research work on residue disposal has provided new concepts on the interaction between organic components and soils as well as new handling technologies (e. g. pelletizing of organic residues). The trend to conserve energy has led scientists to study the minimal tillage system, to find ways of replacing conventional inorganic fertilizers with natural organic prod ucts or microbial preparations, and to develop new composting methods. The drive to achieve higher yields in commercial greenhouse farming has led to a search for optimum substrates as growth media and for improved management techniques. This has led to the introduction of organic substitutes for peat, nota bly those originating from agricultural wastes. Another important aspect is the current interest in organic farming, where use of synthetic chemicals is avoided or prohibited. An increasing percentage of the population in highly developed countries is willing to pay premium prices for food produced on soils where inorganic fertilizers and other agricultural chemicals have not been used.
