In addition to the usual review of the recent world food and agriculture situation, each issue of The State of Food and Agriculture from 1957 has included one or more special studies of problems of longer-term interest. This year's edition focuses on the basic factors affecting the growth of productivity in agriculture, as well as the use of fertilizer.

The use or fertilizer increased during the 90 years following its introduction about 1850, at a fairly constant rate (apart from world war and economic depressions), reaching about 9 million tons per year just before the second world war.
