Molybdenum (Mo) deficiencies in field-grown plants were first recorded more than fifty years ago. This book condenses all the information currently available on the subject of molybdenum as it relates to soils, crops and livestock. The book reviews our knowledge of the chemistry and mineralogy of Mo, the extraction of available Mo from various soils, the various analytical methods of determining Mo in soils and plants, the biochemical role of Mo in crop production, the technology and application of Mo fertilizers to crops, the response to Mo of various temperate and tropical crops, Mo deficiency and toxicity in various plant species, the interaction of Mo with other plant nutrients, and the distribution of Mo within the plant. Factors affecting the availability of soil Mo to plants and Mo status in the semi-arid and sub-humid tropics are also discussed.

Molybdenum (Mo) deficiencies in field-grown plants were first recorded in Australia more than 55 years ago, and this book condenses all the information currently available on the subject of Mo as it relates to soils, crops, and livestock. The book reviews our knowledge of the chemistry and mineralogy of Mo, the extraction of available Mo from various soils, the various analytical methods of determining Mo content in soils and plants, the biochemical role of Mo in crop production, the technology and application of Mo fertilizers to crops, the responses to Mo of various temperate and tropical crops, Mo deficiency and toxicity in various plant species, the interaction of Mo with other plant nutrients, and the distribution of Mo within the plant. Factors affecting the availability of soil Mo to plants and Mo status in the semiarid and subhumid tropics are also discussed. The book will be a valuable reference tool to assist agricultural researchers, professors, and extension personnel.

Obtaining informed consent from mentally challenged patients in psychiatry clinical research has always been a challenge for researchers posing many ethical concerns and procedural hurdles due to participants' impaired ability to judge the reality. Researchers, ethicists, and policy makers are struggling towards developing and implementing appropriate strategies and approaches optimizing the informed consent procedure in psychiatry clinical research to find a balance between risk-benefit ratio, research advancement, and autonomy of the study subjects. This book critically reviews the various ethical issues and challenges associated with informed consent, their underlying reasons, and investigate the appropriate strategies and practices needed to be adopted while obtaining informed consent from subjects with impaired consent capacity, participating in psychiatry clinical research.
