| Abstract/Contents: | "Crop production to feed and clothe the nation during the present emergency will depend more than ever before upon fertilizers. In order to meet the crop production goals set by the Production Marketing Administration for 1951, the estimated amount of nitrogen, phosphoric oxide, and potash required will approach 5,000,000 tons. According to recent estimates, there will be 220,000 tons more nitrogen and 175,000 tons more potash, but 139,000 tons less phosphoric oxide available this year than were used last year. Under normal conditions, the supplies of nitrogen and potash would be ample, but there would be a shortage of about 8 per cent of phosphate material. To meet the increased production as set by the crop production goals, there is likely to be a shortage of nitrogen, phosphate, and potash materials, but most phosphates, amounting to about 1/2 million tons. About 35 per cent of the sulfuric acid produced in the United States is used in making fertilizers, especially phosphates and ammonium sulfate. The allotments of sulfuric acid made to the fertilizer manufacturers last October were 20 per cent less than the amount used last year. This cut is the major bottleneck in phosphate fertilizer production. The available supply of phosphate fertilizers can be made to go farther, however, by reducing its content in mixed fertilizers in areas where more phosphate is used than is needed for maximum crop yields, and by the more efficient use of phosphate fertilizers by band placement instead of broadcast applications. In spite of larger total supplies of nitrogen fertilizers than ever before, there is likely to be some shortage of the solid granular forms. Liquid ammonia and anhydrous ammonia will have to be used in larger quantities. This will entail some changes in methods of fertilizer application and cause some hardship in mixed fertilizer production. With proper use, there should be no serious shortage of nitrogen fertilizers this year. This applies equally to potash if high level production is continued. All factors considered including normal weather conditions, and assuming judicious use of the available supplies of fertilizers, it should be possible to meet the crop production goals for 1951 and keep the lawns, golf courses, and parks green." |
