The exhaustion of soils in the United States has increased with great rapidity in recent years, and this has resulted in the establishment of great fertilizer industries, there being invested in factories for this purpose alone in the United States about $70,000,000, and yet the fertilizer industry is said to be only in its infancy. The world's chief supply of nitrogen comes from the Chilean desert, from which was exported in one recent year $75,000,000 worth of nitrate, practically 80 per cent of which was used in agriculture. During the last decade the exportation of Chilean nitrate has increased 60 per cent in quantity, 60 per cent in price, and 250 per cent in total value. The Chilean Government estimates that the nitrate fields will be exhausted in about forty-five years. The only other material sources of nitrogen are by-products of other industries, in no way connected with agriculture. In the United States these by-products come chiefly from packing houses, in the form of blood and tankage, and from gas plants and coke ovens, in the form of sulphate of ammonia. Fish scrap, cotton-seed meal, animal skins, and even the offal from whaling ships, are used by the fertilizer manufacturers for their nitrogen content. In fact, the world is being scoured for nitrogenous substances for use as fertilizers, and the supply in available form is entirely inadequate to the demand.
