Essential and Non-essential Metals in Plants: Deficiency, Phytotoxicity, and Tolerance offers a comprehensive exploration of the critical roles that metals play in plant health and agriculture. This book delves into the physiological functions of essential metals like iron, zinc, copper, and manganese, and examines the harmful effects of non-essential metals such as cadmium, lead, and arsenic. Each chapter focuses on a specific metal, detailing its importance in plant growth, the impact of its deficiency, and the toxic consequences of its excess.The book addresses the growing concerns of metal deficiencies in modern agriculture, especially in the face of climate change and soil degradation. It also covers broader themes, including the mechanisms of metal uptake and transport within plants, the role of microbial interactions in enhancing metal availability, and the potential of phytoremediation to mitigate metal toxicity in contaminated soils.By integrating insights from molecular biology, environmental science, and agronomy, this book bridges the gap between fundamental research and practical applications. It is an invaluable resource for researchers, educators, and practitioners aiming to develop effective nutrient management strategies, ultimately contributing to sustainable agricultural practices and food security. This book provides up-to-date information, practical insights, and innovative research, establishing itself as an essential guide in the field.
