Like most comets, I-A-A contains molecules of ammonia and nitrogen, along with water, presumed building blocks of the solar system. But another satellite, the International Ultraviolet Explorer, also found surprising indications of sulfur molecules. Said University of Maryland Astronomer Michael A'Hearn: "The sulfur may be one of the few things we see that actually reside in the comet's nucleus." The most stunning observational feat came when the big, 1,000-ft. radio telescope in Arecibo, PR., managed to bounce radar waves off the fleeting object and perhaps settled the old argument over whether cometary...
Makers of fertilizers and pesticides will fare little better. In the past two years, U.S. use of fertilizers has fallen from 53.3 million tons to an estimated 43 million tons. This year industry experts estimate that even though many U.S. ammonic plants, which produce nitrogen fertilizer, have already been closed, those that remain will be operating at only 73% of capacity. As a result, prices are falling and profits are being squeezed. International Minerals and Chemical, a major fertilizer maker in Northbrook, Ill., will earn only about $3 per share this year, compared with $4.56 last year, according to Dean...
...erosion on acreage set aside under PIK. Some such seeds are already in short supply. Says Bob Reichert, a spokesman for DeKalb-Pfizer Genetics, a major seed producer: "Corn, soybean and sorghum seeds will suffer, but our Sudax, a sorghum sudan grass seed, is almost sold out, and our nitrogen-fixing alfalfa blends are in good demand. That eases the impact...
Brown and Sprague acknowledge that their harvests are bigger than the average tongman's. But the fact is that none of the watermen are getting huge hauls these days. Nitrogen, carried into the bay by runoff from neighboring farm lands, has lowered the Chesapeake's oxygen level. The primary victims are the oysters, whose numbers have been declining in recent years. The secondary victims are watermen like Brown, whose family has been working the water for three generations, and Sprague, a Californian who was sent to Maryland as a serviceman and liked it so well that he stayed...
...suit. Despite all efforts during the flight, the suit would not reach the required pressure, 4.3 Ibs. per sq. in. (Although this is only a third of the earth's normal atmospheric pressure, it is adequate because the astronauts are breathing pure oxygen rather than the oxygen-nitrogen mix that they would get at sea level...
