Résumé :
Excerpt from Prewar World Production and Consumption of Plant Foods in Fertilizers

The leading prewar producers of nitrogen were Germany, Chile, Japan, and the United States. German production was nearly three times that of Chile and, in fact, slightly exceeded the combined production of Chile, Japan, and the United States. The production of these latter three varied from each other by _less than tons a year. Ger many also was the largest consumer of chemical nitrogen; the United States, Japan, and France followed. German consumption was about 70 per cent greater than that of the United States, more than double that of Japan, and nearly 3% times that of France.

Germany ranked fifth with regard to the quantity of nitrogen used per unit area of arable land and fourth for that used on the basis of arable land and permanent meadows and pastures. Consumers of more nitrogen than Germany per unit of arable land were:' The Netherlands, more than twice as much; the belgo-luxemburg Economic Union, 50 percent more; Japan, about 40 percent more; and Egypt, about 11 percent more. Germany in turn used more than 12 times as much nitrogen per unit of arable land as the United States, which ranked twenty-second. The belgo-luxemburg Economic Union, the Netherlands, and Japan exceeded Ger many in, the use of nitrogen per unit area of arable land and permanent meadows and pastures. The United States ranked thirteenth in this category.
