Fertilizers consumption

The economic magnitude of the U.S. fertilizer iadustry is iadicated by the yearly value of products which approaches 3 biUioa. U.S. fertilizer consumption represeats only about 13% of the total world consumption. Thus the aimual value of worldwide consumption is at least 22 biUion. The world investment for production faciHties to produce these quantities of fertilizer is also very high (114).

Plant nutrient sulfur has been growing in importance worldwide as food production trends increase while overall incidental sulfur inputs diminish. Increasing crop production, reduced sulfur dioxide emissions, and shifts in fertilizer sources have led to a global increase of crop nutritional sulfur deficiencies. Despite the vital role of sulfur in crop nutrition, most of the growth in world fertilizer consumption has been in sulfiir-free nitrogen and phosphoms fertilizers (see Fertilizers).

Between 1970 and 1978, U.S. sulfur demand grew from 9.2 to about 12 million long tons per year, equivalent to an average annual rate of increase of about 3.4 percent. Over the forecast period, we anticipate an average annual increase of about this same rate. Our estimate assumes that the U.S. will continue to maintain world leadership as an exporter of upgraded phosphates, and that growth in domestic phosphate fertilizer consumption will average about 3 percent per year.

As shown in Figure 3.6, from 1960 to 1989, there was a sustained increase of almost 6% per year in world nitrogen fertilizer consumption - with temporary set-backs due to the oil crises in the 1970 s. From 1989 to 1994, world nitrogen fertilizer consumption fell. This was due mainly to the decline in use in the countries of Central Europe and the former Soviet Union. Consumption in Western Europe also fell, but all of these decreases were partially offset by increased consumption in Asia36. 

From 1994 to 1998 world nitrogen fertilizer consumption increased at an average rate of 3% per year. Socialist Asia, South Asia and Latin American led the consumption increases. Consumption in Western Europe stabilized while demand in the former Soviet Union continued to fall. From 1998 to 2000, world nitrogen fertilizer consumption increased more slowly than it had in the previous period36. 

From 2000 to 2005, world nitrogen fertilizer consumption is forecast to increase by 2.3% per year. A gradual decline is expected in Western Europe and Japan. The consumption increases are forecast to occur primarily in the regions listed in Table 3.4 ...

Since no economical nitrogen fixation process that starts with nitrogen oxides has been discovered, ammonia has developed into the most important building block for synthetic nitrogen products worldwide. Prior to World War II, ammonia production capacity remained relatively stable. But during the war the need for explosives caused an increase in the production of ammonia for nitric acid manufacture. Then, after the war, the ammonia plants were used to manufacture fertilizers. As a result, there was a rapid increase in fertilizer consumption. The advantages of fertilizers were emphasized, and production capacity increased by leaps and bounds. 

On a worldwide basis, nitrogen fertilizer consumption accounts for more than 85 percent of the total nitrogen industry. In the United States, with its significant industrial markets, fertilizer use accounts for only approximately 80 percent of total nitrogen consumption.35 About 97 percent of nitrogen fertilizers are derived from synthetically produced ammonia. The rest are produced as... 

An attempt was made to calculate the total worldwide annual removal by crops of the three major and three secondary nutrients (Table 9.15). These crude estimates indicate that nearly 70 Tg of plant nutrients are cycled annually through the world s cultivated crops, which approaches the total world fertilizer consumption of N, P2OS, and K2O in 1975, calculated to be about 82 Tg (Table 9.5). This does not suggest that there is a high...
