The purposes of this publication are to present current information and to project through 1980 the world supplies of fertilizer as related to crop production requirements. There are critical shortages of fertilizer today which are related principally to energy shortages. These fertilizer shortages pose problems not only for the American farmer as he seeks to improve production efficiency at a time of marked inflation, but also for those developing countries which are vitally in need of food. The information contained herein is not only current but technically sound. The contributing authors are qualified specialists in their fields.
