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

Biofertilizers are seen as an important alternative technology, since the negative externalities of chemical fertilizers have become well known. The use of the latter has led to considerable environmental cost. Biofertilizers do not pollute the soil and do not disrupt the ecological balance, and hence are environment friendly. An increasing number of farmers are using biofertilizers, and the numbers of biofertilizer manufacturing units have also grown considerably. Organic farming system in India is not new and is being followed from ancient time. It is a method of farming system which primarily aimed at cultivating the land and raising crops in such a way, as to keep the soil alive and in good health by use of organic wastes (crop, animal and farm wastes, aquatic wastes) and other biological materials along with beneficial microbes (biofertilizers) to release nutrients to crops for increased sustainable production in an eco friendly pollution free environment. Organic farming has emerged as an important priority area globally in view of the growing demand for safe and healthy food and long term sustainability and concerns on environmental pollution associated with indiscriminate use of agrochemicals. Going organic may be a clear way of getting back to basics and getting away from the havoc chemicals can wreak on our health and our environment but the basics themselves may not be so clear. This book provides the view of immense potential of biofertilizers as a supplementary nutrient source for the crops and covers all major types of bacterial fertilizers. The major contents of this book is crop response to biofertilizers, nitrogen fixation, phosphate solubilising microorganisms, application and evaluation techniques, biogas production, pest and disease management system in agriculture, production, promotion, quality control, marketing, future research planning, photographs and details of machineries, list of manufacturers and suppliers of biofertilizers and organic farming in directory section. This book will be of use and interest to consultants, researchers, libraries, and entrepreneurs, manufacturers of biofertilizer and for those who wants to venture in to this field.

Fertilizer Technology and Management provides an introduction to the manufacture, marketing and management of commercial fertilizers. It covers the principles and methods of fertilizer production including raw material requirements and intermediaries, fertilizer marketing, and all aspects of fertilizer management such as quality control, logistics and application methods. The book also includes chapters on the role of fertilizers in agriculture, long-term effects of fertilizers on soil productivity and impact of fertilizer production and use on the environmental quality. The subject matter in all the chapters has global perspective with emphasis on developing countries and Indian conditions. Drawing on the author’s long experience of teaching and research in the field of fertilizer science and soil fertility, this book has been designed as textbook for the students of Agricultural Sciences and allied subjects including Agribusiness Management and Environmental Science in the universities and colleges. The professionals involved with any phase of fertilizer production, marketing and use will find this book useful.

Nitrate and nitrite are two ions largely diffused in the environment because they take part in the nitrogen cycle. Moreover, a great part of atmospheric nitrogen may be oxidized to nitrite and nitrate by microorganisms in plants, soil or water. The more stable form of oxidized nitrogen is nitrate ion, but, through microbial activity, it can be reduced to nitrite ion which is more chemically reactive. Nitrate and its salts are widely used, especially as inorganic fertilizers, and for many other purposes such as oxidizing agents, explosives, in the chemical industry and as food preservatives. This book discusses the agricultural uses, management practices and environmental effects of nitrogen fertilizers.

Illustrates current fluid fertilizer technology in the US and abroad, including manufacture, handling, storage, distribution, and use in the field demonstrating how fluid fertilizer facilitates more precise delivery of nutrition to crops. The volume provides the means to analyze fluid fertilizer sys
