Agriculture and the nitrogen cycle

the long version

"Agriculture an dthe Nitrogen Cycle provides a unique, up-to-date assessment of the role of nitrogen fertilizer in the nitrogen cycle. In it, the authors emphasize the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) that brought together the world's leading scientists to examine the nitrogen cycle and related problems."--Jacket.
