...Association in 1898 that, taking into consideration acre yield and population growth, wheat would be scarce enough in 30 years to cause a famine. This year's world wheat surplus (see p. 16) is sufficient commentary on Sir William's prediction. Because of the development of synthetic nitrogen used in fertilizers, and the improvement in wheat strains by selective breeding, the limit of wheat growing has been extended farther north, the acreage yield increased. This Professor Bower pointed out as an example of the contribution of experimental botany to the maintenance of civilization. Realizing the importance...
...York, where no buyer appeared, no one knew exactly what to do with it. By now the U. S. (and every one else) knows well enough what to do with Chilean nitrate. In peacetimes one throws it on the ground as fertilizer. In wartimes one must have nitrogen to make explosives. Out of Germany's War-time need for nitrates came various processes for making synthetic nitrogen. And out of these processes came ever-increasing synthetic competition for the natural Chilean nitrates...
...monopoly on nitrates, which meant that Chile had a monopoly. For practically all the world's natural nitrate comes from a certain desolate plateau high up in the Andes in northern Chile, a 450-mi. stretch utterly barren of water and vegetation.* But since the War, synthetic nitrogen has been steadily rolling up tonnage, while Chilean nitrate has remained almost stationary. Thus, in the "Fertilizer Year" (which begins June 1) of 1927-1928, synthetic production of pure nitrogen was 1,267,000 metric tons, Chilean 390,300. Chemically, Chilean nitrate is superior to synthetic because of its high iodine...
...average of about $41,000,000. In 1928-29, this figure was increased to about $5,000,000. The significance of the comparison made by Dr. Klein and by TIME, however, is not affected by this more recent data, as Germany's exports of synthetic nitrogen have also risen, totaling...
...accomplishments of Academician Claude to date include invention of neon lights to illuminate advertising boards and air fields; a process for capturing gases from coke ovens which are converted into hydrogen, nitrogen compounds, innumerable drugs; a method for liquefying air which is used by the $25,000,000 Air Reduction Company; a method of dissolving acetylene in acetone, a process which yields $20,000,000 in annual sales...
