Controlled Release Fertilizers for Sustainable Agriculture provides a comprehensive examination of precision fertilizer applications using the 4-R approach—the right amount of fertilizer at the right time to the right plant at the correct stage of plant growth. This volume consolidates detailed information on each aspect of controlled release fertilizers, including up-to-date literature citations, the current market for controlled release fertilizers and patents. Presenting the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas, this book provides in-depth insight into state-of-the-art controlled release mechanisms of fertilizers, techniques, and their use in sustainable agriculture. Conventional release mechanisms have historically meant waste of fertilizers and the adverse effects of that waste on the environment. Controlled release delivery makes significant strides in enhancing fertilizer benefit to the target plant, while protecting the surrounding environment and increasing sustainability. - Presents cutting-edge interdisciplinary insights specifically focused on the controlled release of fertilizers - Explores the benefits and challenges of 4-R fertilizer use - Includes expertise from leading researchers in the fields of agriculture, polymer science, and nanotechnology working in industry, academics, government, and private research institutions across the globe - Presents the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas

Fertilizers are key for meeting the world s demands for food, fiber, and fuel. Featuring nearly 4,500 terms of interest to all scientists and researchers dealing with fertilizers, The Fertilizer Encyclopedia compiles a wealth of information on the chemical composition of fertilizers, and includes information on everything from manufacturing and applications to economical and environmental considerations. It covers behavior in soil, chemical and physical characteristics, physiological role in plant growth and soil fertility, and more. This is the definitive, up-to-date reference on fertilizers. This book is not available for purchase from Wiley in the country of India. Customers in India should visit Vasudha Research & Publications Pvt. Ltd. at www.fertilizer-encyclopedia.com

The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.

This Manual of Fertilizer Processing, which is the fifth volume of the Fertilizer Science and Technology series. Francis (Frank) T. Nielsson, the editor of the book, has over 40 years of experience in the fertilizer industry, ranging from ammonia manufacture to the extraction of uranium from phosphoric acid, but he is best known for his work with compound or “mixed” fertilizers—fertilizers that contain two or more of the primary plant nutrients: nitrogen, phosphorus, and potassium. Compound fertilizers also may contain one or more of the ten other elements that are essential to plant growth.

It is hoped that this paper will bring to the reader's attention the fact that the mode of addition of micronutrient materials of fertilizers is a factor that can have a significant influence on both the physical and chemical properties of the mixture. It should become obvious that, in adding micronutrient materials, due consideration must be given to such factors as the chemical compatibility of the ingredients, the segregation characteristics of the mixture, solubility in liquid systems, and the uniformity and density of micronutrient distribution sites that will result from field application of the mixture. While the review of addition methods now in use included here should serve as a useful guide, it is hoped that the reader, on becoming aware of the problems, will be stimulated to contrive improvements and modifications in methods that will fit his own needs.
