New research tools and advanced management concepts are presented from a holistic perspective that emphasizes the complexity of the nitrogen cycle. Nitrogen in Agricultural Systems provides an extensive review of the principles and management implications related to nitrogen in the soil-plant-water system. More than thirty leading experts address nitrogen in the context of environmental protection and the efficient use of resources. Significant advances have broadened the perspective from which authors discuss their specific views on each aspect of the nitrogen cycle. This volume reviews the sources and forms of nitrogen in the environment and expands discussion of nitrogen loss mechanisms from soil and vegetation. Nitrogen transformations remain a common thread throughout the discussion of biological, chemical, physical, and weather-related interactions. The subjects of accountability and nitrogen budgeting are emphasized because they have a strong bearing on management decisions and environmental implications. The concept of soil-plant resiliency is introduced as a framework to better understand how climate, soils, and plants interact to broadly delineate cropping eco-regions. Sections on economic considerations and water quality are included. The nitrogen management principles described promote judicious global management of our nitrogen resources. The editors and authors provide a truly excellent book.
