The Soil: Plant System

The Soil-Plant System in Relation to Inorganic Nutrition focuses on the soil-plant system in relation to the inorganic nutrition of plants. More specifically, the book investigates the dynamics of ion uptake in relation to those physical and chemical processes that must be considered both in understanding any observation made on the soil-plant system and in predicting the results of any stress placed on the system. This volume is organized into two parts encompassing seven chapters and begins with an overview of the inorganic nutrition of plants grown in the soil-plant system. This book then discusses the uptake of nutrient ions from the soil into the plant system. The emphasis is on fundamental aspects of ion movement from the soil into and through the soil solution, then into the plant root, and finally into the shoot. The next chapters consider the more practical aspects of the supply of nutrients to plants grown in the soil-plant system and how it can best be supplemented. This book examines the use of isotopes with respect to solid-phase-soil-solution relationships; movement of ions to the roots, into the roots (active or passive), and translocation to the shoot; the mobility of nutrients; laboratory, greenhouse, and field evaluation of soil nutrient supply; and when, where, and what kind of fertilizer to apply. This book will be of interest to botanists, biologists, students, and research workers engaged in the physical and biological sciences.

Toxic Substances in Crop Plants

"Continuing disquiet over the use of animal by-products in livestock nutrition has provided renewed impetus for the greater exploitation of conventional and novel crop plants both as food and as industrial raw materials. However, a major factor restricting the utilisation of such crops in animal nutrition is the presence of a diverse array of toxic substances capable of inducing effects ranging from loss of hair and wool to severe neurological disorders and even death. Significant advances have been made to establish the nature of these compounds and to assess their effects in animals and man. As in other branches of biomedical research, these developments have been achieved through the multidisciplinary efforts of chemists, biochemists, toxicologists, nutritionists and molecular geneticists. This volume reviews current knowledge of toxic substances in crop plants with particular reference to their anti-nutritional effects in animals and man and the potential for detoxification. The distribution and ecological significance of these compounds is also addressed. Key Features. Reviews current knowledge of toxic substances in crop plants. Assesses distribution and ecological significance of compounds"

Toxins in Plant Disease

Toxins in Plant Disease presents a comprehensive coverage of plant disease toxins, both those for which there are reasonable evidence and those with fewer credentials. This book is primarily concerned with the mechanism wherein substances that interfere with metabolism or that alter the normal structure of protoplasm are produced and released (category 1); this includes the traditional toxins, which are usually of low molecular weight. It also describes category 2 mechanism, wherein substances that interfere with normal control of growth and development are produced and released; these microorganisms are classified as growth-affecting compounds. Moreover, this text addresses some high-molecular-weight compounds that contribute to vascular dysfunction. It further talks about the production, isolation, assay, genetics of production, mechanism of action, structure-activity relationship, metabolism, and applications of these toxins. This publication will provide a rational basis for future investigations and contribute to the eventual understanding of the role that toxins play in disease causation.

Trace Elements in Human and Animal Nutrition: Fifth Edition 1986

The major change in the format of the fifth edition is the presentation of the book in two volumes, necessitated by the rapidly increasing knowledge of metabolism, interactions, and requirements of trace elements ... The guiding principle was to present the minimum of results that would serve as a logical foundation for the description of the present state of knowledge. Recent results of research were accommodated by devoting new chapters to the subjects "Methodology of Trace Element Research" and "Quality Assurance for Trace Element Analysis" and by expanding the discussion of lithium and aluminum in separate, new chapters. The first two subjects are of outstanding importance as determinants of future progress. The concern for the quality of analytical data motivated the authors of the individual chapters to review critically and, where necessary, revise analytical data presented in the previous editions. The rapid progress of trace analytical methodology since the mid-1970s has changed what had been accepted as normal for the concentrations of many trace elements in tissues and foods. The new data reflect the present state of the art in trace element analysis, but they may be subject to future revision.
