One hundred years ago approximately 25,000 tons of the three primary nutrients were used. This had increased to about goo 000 tons by 1900 and to 18 million tons by 1910. Since ttien it has zoomed to the piesent consumption of 6',i to 7 million tons a year. about manure and other organic materials being applied to the soil to increase We read crop yields since before the time of Christ. Greek litera-tui- e mentions that green crops were plowed under to enrich the soil. Roman literature tells of green manuring, application of manure, and growth of legumes for soil improvement. The early American colonists found the Ameiican Indians using fish as fertilAmerican izers. The South Indians were using guano (bat Today fertilizers manure). more convenient come in forms. was originally Phosphate form. produced i n powder Now it is granulated for ease in handling and applying uniformly on the land. There is an increased amount of fertilizers being used and liquid USU tests indicate that 20 pounds of nitrogen per acre increased yields an average of one bushel per acre. FIRST IN AMERICA today ammonia and liquid phosphoric acid are replacing dry materials in many farming situations. these Goperal 1 y liquids are less expensive to ship, require less labor in handling and are eaisly adapted to mechanical application. We expect to see the trend to greater use of liquid fertilizers continue. Amazingly, prices have not gone up comparable to most other farm costs. Prices of fertilizer nutrients that are being purchased today are not much higher than they were 60 years ago. Perhaps most significant of all modern trends in use of commercial fertilizer is the emphasis now being placed on fertilizing crops as a part of rotation rather than fertilizing the individual crop. When this is done in conjunction with soil testing as a guide, most effective use of fertiliz- ing can be made. A few years ago recommandations were directed at correcting soil deficiencies. To a large extent Today the aim is to maintain adequate levels of the fertilizer elements in the soil. This is vital if food production efficiency in the space age is to keep pace with narrowing profit margins and the skyrocketing "population Heavier fertilizer application the few ways left for the farmer to cut his cost per is one of unit of production. buy fronT"" Mt.

Steel's big Geneva Works, near Utoh, first of its kind at a major steel mill m the United States. At this chemical plant, coke oven gas from steelmaking operations is converted into anhydrous ammonia which is stored in the two big hortonspheres (right). Some of the anhydrous ammonia goes to produce ammonium nitrate. This nitrogen-ric- h fertilizer is converted into solid form as pi ills in the prilling tower (left). Ammonium sulfate, a third member of the USS fertilizer family, is turned out in another section of Geneva's coal chemiccjs producing facilities. high-grad- y INCREASE YOUR PROFITS CROPS WELL-FE- D are money makers UsS) Anhydrous Ammonia Are ' our cropswell-fed- ?
