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.

Edited by One of the Best Specialists in Soil Science Recent studies reveal that Phosphorus (P) in the form of phosphate, a macronutrient essential for plant growth, and crop yields can influence the bioavailability, retention, and mobility of trace elements, metal(loid)s, and radio nuclides in soils. When this occurs, phosphates can affect the dynamics of heavy metals and influence soil characteristics, impacting soil mobility and toxicity. Phosphate in Soils: Interaction with Micronutrients, Radionuclides and Heavy Metals utilizes the latest research to emphasize the role that phosphate plays in enhancing or reducing the mobility of heavy metals in soil, and the soil-water-plant environment. It provides an in-depth understanding of each heavy metal species, and expands on phosphate interactions in geological material. Composed of 12 chapters, this text: Provides an overview of the reactions of metal(loid)s and common P compounds that are used as fertilizer in soils Emphasizes the effect of phosphorus on copper and zinc adsorption in acid soils Discusses findings on the influence of phosphate compounds on speciation, mobility, and bioavailability of heavy metals in soils as well as the role of phosphates on in situ and phytoremediation of heavy metals for contaminated soils Places emphasis on the influence of phosphate on various heavy metals species in soils, and their solubility/mobility and availability Provides extensive information on testing various high phosphate materials for remediation of heavy metal, micronutrients, and radionuclides contaminated sites Explores the reactivity of heavy metals, micronutrients and radionuclides elements in several soils Presents a case study illustrating various remediation efforts of acidic soils and remediation of Cu, Zn, and lead (Pb) contaminated soils around nonferrous industrial plants Emphasizes the significance of common ions (cations and anions) on phosphate mobility and sorption in soils, and more The author includes analytical and numerical solutions along with hands-on applications, and addresses other topics that include the transport and sorption modeling of heavy metals in the presence of phosphate at different scales in the vadose zone.

Phosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%–30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil–water–sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant–microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.

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.

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.

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.
