The book "Nutrient Cycling in Terrestrial Ecosystems" offers a comprehensive analysis of nutrient cycles in terrestrial ecosystems and their significance for plant growth and ecosystem sustainability. It is divided into several parts, beginning with the fundamentals of nutrient cycling, including the cycles of carbon, nitrogen, phosphorus, sulfur, and micronutrients. Special attention is given to the role of root exudates and microorganisms in the rhizosphere that support nutrient cycling. The second part of the book addresses nutrient cycling at the ecosystem level, discussing various habitats such as agricultural systems, pastures, natural grasslands, arid regions, tundras, and forests. The concluding chapter presents current models of nutrient cycling. Through a thorough examination of nutrient cycles at different scales and an emphasis on interdisciplinary approaches, this work is aimed at both scientists and practitioners interested in enhancing sustainable economic yields from managed ecosystems and protecting natural ecosystems.
