To bring the latest knowledge and research advances in efficient management of phosphorus (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

Born of the pressing need to improve crop yield worldwide, The Use of Nutrients in Crop Plants presents a comprehensive review of essential crop nutrients. It provides information on nutrient uptake, discusses methods to improve crop productivity without degrading the environment, and includes authoritative coverage of experimental results regarding macro- and micronutrients. Offering extensive tables and figures, the text compiles data on agricultural production, organic and inorganic fertilizer consumption, maximization of nutrient use, and improvement of efficient crop yield.

Roots have a significant role in crop production. This volume examines root architecture and development dynamics to help plant and soil scientists and those in related fields improve crop productivity. The author emphasizes production, plant nutrition, and soil chemistry relative to root growth and functions. Chapters cover root morphology and functions; nutrient and water uptake; root-soil, root-environment, and root-microbe interactions; and the physiology of root crops. The book also explores management practices to improve root growth. Information in the book is supported by experimental results.

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.

The judicious use of nitrogen in crop production is highly desirable for both economic and environmental reasons, because much of the nitrogen applied to crop plants goes unused, resulting in environmental problems and waste. This book reviews the practical and theoretical aspects of nitrogen management in crop production. Chapters address the functions of nitrogen, nitrogen loss in the soil¿plant system, diagnostic techniques for nitrogen requirements, management of soil organic matter, nitrogen interaction with other nutrients, biological nitrogen fixation by legumes, and management practices to improve nitrogen use efficiency.

The author emphasizes production, plant nutrition, and soil chemistry relative to root growth and functions. Chapters cover root morphology and functions; nutrient and water uptake; root-soil, root-environment, and root-microbe interactions; and the physiology of root crops. The book also explores management practices to improve root growth. Information in the book is supported by experimental results.

This new edition of a bestseller examines plant nutrition's role as one of the most important limiting factors that must be overcome to optimize food production. Extensively revised and updated, the new edition provides comprehensive coverage of topics such as genetic, physiological, and agronomic bases of crop growth. It covers the soil-plant-climate relationships that govern the growth and mineral nutrition of crops in temperate and tropical regions. Offering several new figures, references, and tables, the book contains two new chapters covering remediation of heavy metal contaminated soils and cover crops.

Explores how to maximize essential nutrients uptake and use efficiency by food crops and how to improve productivity without degrading the environment. This work covers nutrients and their cycle in soil-plant systems, functions, and deficiency symptoms. It emphasizes field conditions, crop production and soil chemistry.
