This richly illustrated edition of an established classic deals with the chemistry and biology of soil nutrient availability. Provides information regarding the elements present in soils and the extent to which these elements can be used by plants in order to grow. Nutrient uptake by plant roots, rhizosphere microorganisms and application of the mechanistic uptake model as well as such elements as phosphorus, potassium and water are among the topics discussed.

This book focusses on the thermodynamics of soil nutrient bioavailability, and in particular the most important plant nutrients such as, phosphorus and potassium, among major nutrients, and zinc among micronutrients. It proposes a paradigm shift in the approach to global soil testing procedures. Historically, soil testing has been used to quantify availability of essential plant nutrients to field-grown crops. However, contemporary soil tests are based on philosophies and procedures developed several decades ago, without significant changes in their general approach. For a soil test to be accurate, one needs to clearly understand the physico-chemico-physiological processes at the soil-root interface and, an understanding of soils and plant root systems as polycationic systems is essential. It is this knowledge that leads to sound prescriptive soil nutrient management inasmuch as soil nutrient bioavailability vis-à-vis fertilizer application is concerned, because, of all the factors which govern sustainability in crop production, the nutrient factor is the most important, yet, it is also least resilient to management. This book provides a clear scientific basis of the thermodynamics of soil nutrient bio availability, which routine soil testing does not provide

This is an integrated review of the mechanisms controlling plant nutrient uptake and how plants respond to changes in the environment. Among key topics covered are: soil nutrient bioavailability; root responses to variations in nutrient supply; nitrogen fixation; root architecture; life span; mycorrhizae; responses to climate change. The book helps us understand the mechanisms that govern present-day plant communities and to predict the response of plants to a changing climate.

This book will address the importance of the soil management concept, vis-à-vis chemical fertilizer use on soil. Historically, soil testing has been used to quantify bio availability of plant nutrients to field grown crops. However, contemporary soil tests are based on philosophies and procedures developed several decades ago without significant changes in their general approach. For a soil test to be accurate, one needs to clearly understand the physico-chemico-physiologic processes at the soil-plant root interface, and, an understanding of soils and plant root systems as polycationic systems is essential. It is this knowledge that leads to sound prescriptive soil management practices inasmuch as nutrient bioavailability vis-à-vis chemical fertilizers application is concerned, because, of all the factors that govern sustainability of crop production, the nutrient factor is the most important, yet, it is also the least resilient to effective management. The author’s research spanning over three decades in Europe, Africa and Asia, establishes the fact that precise quantification of the nutrient’s “buffer power” holds the key to a clear understanding of the plant bioavailability of some of the most important plant nutrients in crop production, such as, phosphorus, potassium and zinc. “The Nutrient Buffer Power Concept” attempts to clearly explain the bio availability of the three plant nutrients named above on the basis of the diffusion model, as that is the process by which these three important principal plant nutrients are absorbed from the soil by the plant root. Possibly, other plant nutrients which are taken up by the plant roots by the same diffusive model, would also conform to the principles of the concept. A thorough knowledge of thermodynamic principles on the part of the researcher is an absolute pre requisite for this. The book chronicles more than three decades of the professional journey of the author in Europe, Africa and Asia, understanding soil for human sustenance, and developing the revolutionary soil management concept, now globally known as, "The Nutrient Buffer Power Concept" , which has brought the author a string of international recognitions, including the nomination for the "Alternative Nobel Prize" (The Right Livelihood Award),of Sweden, and succour to millions to poor and marginal farmers across Africa, Asia and Latin America.

Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

This book begins with an overview of current thinking on bioavailability, its definition, cutting-edge research in speciation and advancement in tools for assessing chemical bioavailability in the terrestrial environment. The second section of the book focuses on the role of chemical speciation in bioavailability. Section three addresses bioavailability and ecotoxicity of contaminants and leads into the next section on bioavailability of nutrients and agrichemicals. Subsequent sections provide an overview of tools currently being used and new cutting-edge techniques to assess contaminant bioavailability. The last section of the book builds on previous sections in relating bioavailability to risk assessment and how this could be used for managing risks associated with contaminated land. Provides the latest information on developing concepts and definitions of bioavailability Includes a discussion of bioavailability and ecotoxicity of contaminants and bioavailability of nutrients and agrichemicals for applications in agriculture Analyzes tools for assessing bioavailability and the role of bioavailability in risk assessment and remediation
