Fertilizers shares

So it is interesting when two mature sciences are forced by the facts of nature and a shared subject to confront each other s ways of thinking, both of them productive and yet, and yet... seemingly incommensurate. This is what has happened, is happening, between chemistry and physics their preeminent and fertile shared ground is the contemporary solid state, with its exciting materials. This book, in its unique way, shapes a way not just to coexistence of chemistry and physics in materials science, but to a productive future. A future shaped by computational techniques (for theory definitely has a major role to play here) that are respectful of both chemistry and physics. 

Worldwide, triple superphosphate, over the period 1955 to 1980, maintained about a 15% share of the phosphate fertilizer market (Fig. 8). World consumption for the year ended June 30, 1991 (9) was equivalent to 3.6 x 10 t of P20, which was about 10% of world fertilizer P2O5 consumption. In the United States, consumption for the year ended June 30, 1990 (Fig. 7) was equivalent to about 240 x 10 t of P20, which represented only 6% of U.S. fertilizer P2O5 consumption.

Furthermore, the share cf crops lost to Insects has nearly doubled during the last 40 years (Table 1), despite a more than 10-fold increase in both the amount and toxicity of synthetic insecticide used (17-19). Up to the present time the increased insect losses, in terms of yields per hectare, have been offset by increased crop yields obtained through the use of higher yielding varieties and greater use of fertilizers and other energy-based inputs (20, 21). 

In this interview Katy shares her view that chemical exposures can lead to an inability to tolerate stress, to loss of mental functioning, to fear and to violence. Since I met with her, two studies have been published that validate her remarks. One, a University of Wis-consin-Madison study published in the journal Toxicology and Industrial Health, January-March 1999, found that the pesticide-fertilizer mixtures commonly found in groundwater can affect patterns of aggression and the ability to learn, and causes hormone disruptions that increase sensitivity to stimuli, irritability and immune dysfunction. A University of Arizona study published by Environmental Health Perspectives in June 1998 showed a decrease in mental ability and an increase in aggressive behavior among children exposed to pesticides. 

A number of trends discussed above favor the eventual use of CBRN weapons. The willingness to commit mass murder is primary among them. Cross fertilization among terrorist groups increases the likelihood that terrorists will develop and use more sophisticated tactics and weapons as groups share information and resources on materials, methods, and tactics. Splinter groups are seen as more likely to attempt innovation and the spread of technology will put the power to develop ever more sophisticated weapons in the hands of terrorists. 

Most certainly the greatest culprit in excess nutrients is agriculture. Nevertheless, urban areas contribute a grossly disproportionate share of these chemicals (Table 4.5), creating acute local stream problems. Lawn fertilization contributes to this effect, though to a degree not yet fully determined. 

Pseudo commodities differ from true commodities in that they are not only defined by their chemical structure but that their application characteristics are optimized, too. The value added is also low and the share of raw material costs is high. However, for each product group a number of products with different application characteristics exists. Typical examples are fertilizers, solvents, elastomers, etc. 

Commercial grades of AN include solutions that contain about 83% AN and solid products. Both grades are used for direct fertilizer applications, or they are blended with other materials to form mixed solid and liquid fertilizers. High density, prilled AN is usually used for direct applications while other solid AN is mixed with phosphate and potash for multi-nutrient fertilizers. Solid AN has lost market share to urea because it has a lower nitrogen content (33-35% for AN vs. 45-46% for urea), plus it costs more per ton. In addition to direct application, AN solutions are mixed with urea to make nitrogen solution fertilizers240. 

In Western Europe, nitrate fertilizer producers had deemed it expedient to set up a cartel arrangement for exporters called Nitrex. But the collapse of demand in countries outside its area had prevented it from functioning properly, sparking a fight for market shares even within the community. 

Their total merger project failed through lack of financial means, and it was Kuwait in the end which, through the Kuwait Investment Office, took a 47 percent share in ERT and 24 percent in Cros in 1987 and promised to provide the necessary cash for the two groups to form a joint fertilizer subsidiary.
