Fertilizer supply-demand balances

Fertilizer supply-demand balances are derived from projected demand and estimated supply potential. Because capacity projections are not available for 2004/ 05, supply-demand balances for 2004/05 are based on the projected demand for 2004/05 and the estimated supply potential for 2000. This is done for two reasons First, to estimate how much additional capacity will be needed between 2000 and 2005 to meet the projected demand and in what regions. Second, what are the chances that the required additional capacity will be brought on stream

Phosphate - Both developed and reforming markets are expected to have phosphate surpluses - with a heavy concentration in North America and Eurasia. Although North America has traditionally been a major producer and exporter of phosphate fertilizers, a surplus in Eurasia results from a drastic reduction in fertilizer use during the reform process. In both regions, surpluses will range between 2 and 5 million tonnes and will gradually decrease during the 1995-2005 period. Western Europe will continue to have a deficit.

Supply-demand balance estimates suggest that fertilizer markets during the late 1990s will be dominated by "surpluses under most scenarios and therefore will continue to put downward pressures on prices. However, in... 

Eutrophication. All lakes have a life cycle it is perfectly correct to speak of a young lake or an old lake. Within any lake, there is a delicate balance among oxygen supply animal, plant, and aquatic life and sediments. As we saw with the nymphs in Lake Erie, if there are too many nutrients, such as phosphorus, the lake becomes over-fertilized. Aquatic life proliferates, places too much demand on the limited amounts of oxygen the water can hold, and then begins to die and settle to the bottom, (See Fig. P-6.) Phosphorus, from agricultural runoff and inadequately...
