National Fertilizer Association

Annual figures on fertilizer consumption are issued by the National Fertilizer Association, Inc., in Washington, D. C. In addition, data on the production of superphosphate are prepared monthly for the membership.

In 1962 The Silent Spring, written by Rachel Carson, was published. Carson s book was one of the first that attracted national attention to the problems of toxic chemicals and the effects of these chemicals on the environment. The Silent Spring recounted how the residues of the pesticide DDT could be found throughout the food chain. In aquatic birds, high levels of DDT were associated with reduced fertility. DDT affected the deposition of calcium in avian ovaries, leading to egg shells too thin to survive, thus causing a widespread reduction in many bird species. 

The United Nations has estimated a daily per-person food requirement of approximately 2,400 calories, including 100 grams of protein. This translates to 243 million metric tons of wheat for every billion additional people in the world. More efficient development and use of fertilizers, pesticides, herbicides, fungicides, and so on will be required to increase food production. As this increase occurs, there will be the environmental problems traditionally associated with these chemicals. The runoff from farms and ranches, for ex-... 

A recent national public opinion survey (1) conducted by the National Agricultural Chemicals Association (NACA) revealed that 47% of all Americans believe that pesticides and farm fertilizers are a "major national problem " 55% include chemicals in drinking water in this category and 48% of all Americans also consider pollution of underground water as a "major national problem." These results reinforce the timeliness and importance of this three-day symposium. 

How can you measure turbidity The National Primary Drinking Water Regulations set the standards for public water systems. Turbidity—a measure of the cloudiness of water that results from the suspension of solids in the water—is often associated contamination from viruses, parasites, and bacteria. Most of these colloid particles come from erosion, industrial and human waste, algae blooms from fertilizers, and decaying organic matter.

The National Business Incubator Association estimates that there are fewer than 4000 business incubators worldwide, which means that today China has perhaps 15% of the total. Obviously, China has offered fertile ground for business incubators, and one will find nearly every variety imaginable - general, technology-specific, rmiversity-related, internal state-enterprise, international, etc.

States during the 1980s are given in Table 14.5 for major acid-producing states. The South accounts for about 75 percent of new sulfuric acid production, most of which is captive consumption for phosphate fertilizer production. With its massive phosphate rock deposits, Florida leads the nation in sulfuric acid production, to feed its phosphoric acid plants. Sulfur mines and recovered sulfur from oil and gas operations in Texas and Louisiana provide brimstone feed to sulfuric acid plants. Many of these plants are sited near major waterways to provide cheap transportation for raw materials and fertilizer products. Southwestern sulfuric acid plants usually are associated with smelters that ship the acid by rail to fertilizer plants.
