This study examines the interactions between nitrogen and the ecosystem and discusses nitrogen fertilization practices around the world. Simulation models that play an important role in determining the dynamics of source-sink relationships are presented, helping to pinpoint inefficiencies and develop strategies to synchronize nitrogen supply and demand.
". . .presents the most up-to-date information on nitrogen requirement for various crops and environmental considerations. "
". . .a valuable book. . .deserves a place in the libraries of universities and research institutes. "
---Field Crops Research
". . .an excellent book for a graduate student or researcher working in the area of nitrogen fertilizer use. "
". . .a very helpful compendium. . .A book you need to chain to the shelf. "
