Over forty years ago, concern was first focussed on cadmium contamination of soils, fertilisers and the food chain. Adverse effects on human health were first highlighted nearly 30 years ago in Japan with the outbreak of Itai-itai disease. Since then, substantial research data have accumulated for cadmium on chemistry in soils, additions to soils, uptake by plants, adverse effects on the soil biota and transfer through the food chain. However, this information has never been compiled into a single volume. This was the stimulus for the Kevin G. Tiller Memorial Symposium "Cadmium in Soils, Plants and the Food Chain", held at the University of California, Berkeley, in June 1997 as part of the Fourth International Conference on the Biogeochemistry of Trace Elements. This symposium brought together leading scientists in the field of cadmium behaviour in soils and plants, to review the scientific data in the literature and highlight gaps in our current knowledge of the subject. This series of review papers are presented here and deal with the chemistry of cadmium in soils, the potential for transfer through the food chain and management to minimise this problem. We hope this information provides a sound scientific basis to assist development of policies and regulations for controlling cadmium in the soil environment.

The increasing population densities of Asia, Africa and Oceania are in conflict with the ecosystem. A growing demand for food and fiber causes agriculture to rely heavily upon chemical fertilization, herbicides and pesticides. Rising industrial output creates higher contamination from cadmium, lead, selenium, and other metals. Soils and Groundwater Remediation explores the toxic levels of metals, radionuclides, inorganics, and anthropogenic organic compounds found in the soils and groundwater of Asia, Africa and Oceania. This 14 chapter book reviews the distribution, transformation, and dynamics of the pollutants. The authors also reflect on the impact of Acid-rain. The contributors to this book are well-known scientists from Japan, China, Korea, Malaysia, New Zealand, Australia, and Kenya. The authors address their findings to researchers, educators, government regulators, and students. As the title suggests, the book is ultimately concerned with remediation. Huang and Iskandar feel "the potential for restoring ecosystem health ... in these areas is enormous." The contributions of Soils and Groundwater Remediation will bring science closer to achieving that possibility.

Still the Gold Standard Resource on Trace Elements and Metals in SoilsThis highly anticipated fourth edition of the bestselling Trace Elements in Soils and Plants reflects the explosion of research during the past decade regarding the presence and actions of trace elements in the soil-plant environment. The book provides information on the biogeoch

This book focuses on the recent progress of nanotechnology with emphasis on the interaction between nanoparticles and plants on the cellular level. It is devoted to understanding the pathways of nanomaterials entry into plant cell and their influence on cellular organelle processes and influence on crop yield. It consists of 16 chapters grouped in 3 parts: Part I Cellular mechanisms, Part II Cellular macromolecules, and Part III Implications of nanomaterials. Chapters present the plant response to nanomaterial applications including morphological, physiochemical, and anatomical changes and their effect on plant growth and productivity. The book discusses the mechanisms of absorbance and translocation of nanoparticles and their interaction with the plant cellular biochemical compounds and organelles. It presents the current perspective of nanomaterials influence on cellular processes which include photosynthesis, photorespiration and pigment synthesis and accumulation. In addition, it provides current understanding of the impact of nanomaterials on cellular macromolecules including carbohydrates, lipids, nucleic acids, proteins, hormones, and antioxidant defense activities. Collectively, these processes and biochemical compounds have implications on crop yield. Chapters are written by globally recognized scientists and subjected to a rigorous review process to ensure quality presentation and scientific precision. Chapter begins with an introduction that covers similar contexts and includes a detailed discussion of the topic accompanied by high-quality color images, diagrams, and relevant details and concludes with recommendations for future study directions.

This comprehensive volume covers recent studies into agricultural problems caused by soil and water contamination. Considering the importance of agricultural crops to human health, the editors have focused on chapters detailing the negative impact of heavy metals, excessive chemical fertilizer use, nutrients, pesticides, herbicides, insecticides, agricultural wastes and toxic pollutants, among others, on agricultural soil and crops. In addition, the chapters offer solutions to these negative impacts through various scientific approaches, including using biotechnology, nanotechnology, nutrient management strategies, biofertilizers, as well as potent PGRs and elicitors. This book serves as a key source of information on scientific and engineered approaches and challenges for the bioremediation of agricultural contamination worldwide. This book should be helpful for research students, teachers, agriculturalists, agronomists, botanists, and plant growers, as well as in the fields of agriculture, agronomy, plant science, plant biology, and biotechnology, among others. It serves as an excellent reference on the current research and future directions of contaminants in agriculture from laboratory research to field application.

Like all living things, plants require nutrient elements to grow. The Plant Nutrition Manual describes the principles that determine how plants grow and discusses all the essential elements necessary for successful crop production. The nutritional needs of plants that add color and variety to our visual senses are addressed as well. Altogether, nutritional requirements are given for 143 plants grouped in seven categories from food crop plants to ornamentals. The text begins with an introduction to the basic principles of plant nutrition. Chapters 2 and 3 describe the roles of the major elements and micronutrients. The last two chapters describe techniques for determining the nutrient element status of growing plants through plant analysis and tissue tests. The Plant Nutrition Manual is loaded with information on what plants need for normal vigorous growth and development-free of nutritional stress.
