The world population is projected to reach nine billion by 2050, and in the coming years, global food demand is expected to increase by 50% or more. Higher crop productivity gains in the future will have to be achieved in developing countries through better natural resources management and crop improvement. After nitrogen, phosphorus (P) has more widespread influence on both natural and agricultural ecosystems than any other essential plant element. It has been estimated that 5.7 billion hectares of land worldwide contain insufficient amounts of available P for sustainable crop production, and P deficiency in crop plants is a widespread problem in various parts of the world. However, it has been estimated that worldwide minable P could last less than 40 years. For sustaining future food supplies, it is vital to enhance plant P use efficiency. To bring the latest knowledge and research advances in efficient management of P for economically viable and environmentally beneficial crop production in sustainable agriculture, Phosphorus Management in Crop Production contains chapters covering functions and diagnostic techniques for P requirements in crop plants, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, and basic principles and methodology regarding P nutrition in crop plants. The majority of research data included are derived from many years of field, greenhouse, and lab work, hence the information is practical in nature and will have a significant impact on efficient management of P-fertilizers to enhance P use efficiency, improve crop production, promote sustainable agriculture, and reduce P losses through eluviations, leaching, and erosion to minimize environmental degradation. A comprehensive book that combines practical and applied information, Phosphorus Management in Crop Production is an excellent reference for students, professors, agricultural research scientists, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.

Increasing food production worldwide has become a major issue in the 21st century. Stagnation in grain yield of important food crops in recent years in developed, as well as developing, countries has contributed to a sharp increase in food prices. Furthermore, higher grain yield will be needed in the future to feed a burgeoning world population with a rising standard of living that requires more grain per capita. Technologies that enhance productivity, ensure environmental safety, and conserve natural resources are required to meet this challenge.

By the year 2050, the world's population is expected to reach nine billion. To feed and sustain this projected population, world food production must increase by at least 50 percent on much of the same land that we farm today. To meet this staggering challenge, scientists must develop the technology required to achieve an "evergreen" revolution--one that increases crop productivity without degrading natural resources. With 30 percent new material, the updated and revised third edition of Growth and Mineral Nutrition of Field Crops covers all aspects of crop growth and mineral nutrition that contribute to sustainable, high-yield agriculture. Bringing together international scientific knowledge of crop production and the impacts of agriculture on the environment, this book: * Includes two new chapters on remediation of heavy-metal contaminated soils and cover crops * Covers theoretical and practical aspects of mineral nutrition of field crops * Provides recommendations for judicious use of fertilizers, which will reduce cost of crop production and enhance high crop yields without risking environmental pollution * Provides growth patterns for annual crops and forages * Includes a handful of color pictures of nutrient deficiencies for easy diagnostic purposes To make the book as practical as possible, each chapter is supported by experimental results and extensive references. A large number of figures and tables are also included to save readers time when researching. The overall emphasis of this reference is on the soil's ability to sustain high crop yields and a healthy human population.

Put Theory into Practice

Scarcity of natural resources, higher costs, higher demand, and concerns about environmental pollution ? under these circumstances, improving food supply worldwide with adequate quantity and quality is fundamental. Based on the author's more than forty years of experience, The Use of Nutrients in Crop Plants builds a bridge between theoretical aspects of mineral nutrition and practical applicability of basic principles of fertilization and use efficiency of essential plant nutrients.

Provides Authoritative and Practical Information

The book explores how to maximize essential nutrients uptake and use efficiency by food crops and how to improve productivity without degrading the environment. It covers nutrients and their cycle in soil-plant systems, functions, and deficiency symptoms. The author includes management strategies that can lead to a reduction in the cost of crop production and environmental degradation. He emphasizes field conditions, crop production, and soil chemistry. Comprehensive coverage of essential nutrients and experimental results are accompanied by tables and figures of updated experimental data that make practical information easily accessible.

A Valuable Tool for Improving Crop Yield

Agricultural science is very dynamic in nature and fertilizer practices change with time due to the release of new cultivars and changing production practices in sustainable crop production systems. The Use of Nutrients in Crop Plants provides in-depth scientific information that is applicable through many methods of crop production. It is a valuable tool for improving crop yields at lower cost and less stress on the environment.

One of the main approaches for safeguarding food security, sustainable development has increased demand for knowledge on fertilizer management in crop production. Among essential plant nutrients, nitrogen is one of the most important yield-limiting nutrients, mainly responsible for determining yield and yield components in cereals and legumes. It is also responsible for the activation of many enzymes and, of course, plays an important role in photosynthesis. With a recovery efficiency of less than 50 percent in most cropping systems, a large portion of the nitrogen applied as fertilizer is not used by plants, creating environmental and economic issues. Nitrogen Management in Crop Production covers the critical aspects for the judicious use of nitrogen in cropping systems. This includes appropriate methods of nitrogen application, effective source and timing of application during crop growth cycles, use of an adequate application rate to avoid loss and reduce cost, use of nitrogen-efficient crop genotypes, and use of legumes that fix sufficient amounts of atmospheric nitrogen. There is also a chapter on organic matter and its role in sustainability. This book presents recent information from the international literature, making it relevant for most agroecological regions. Chapters provide experimental results to aid in practical application of the information. The book contains color photos of nitrogen deficiency symptoms to serve as a guide for important crop species, such as rice, dry bean, wheat, soybean, and corn. It also includes numerous tables and figures, providing an easy-to-read reference.
