How much fertilizer is produced today?

Production of artificial fertilizers has skyrocketed from about 20 million tons in 1950 to nearly 190 million tons today–about a third of them nitrogen-based. Fertilizer production will almost certainly keep growing to keep pace with human population, but the amount of aerosols created as a result depends on many factors, including air temperature, precipitation, season, time of day, wind patterns and of course the other needed ingredients from industrial or natural sources. (In parts of Africa, Asia and the Middle East, aerosols or their precursors come mainly from desert dust, sea spray or wildfires.) The largest increases in farm emissions will probably be in Africa, while the slowest projected growth rates are in Europe, says the study.


Where do aerosols come from?

It shows that more than half the aerosol ingredients in much of the eastern and central United States come from farming . In Europe and China, the effect is even stronger. The aerosols form mainly downwind of farming areas, in densely populated places where farm emissions combine through a series of chemical reactions with those of cars, trucks and other sources.


Do agricultural emissions make aerosols?

The fact that agricultural emissions must combine with other pol lutants to make aerosols “is good news,” said Bauer. Most projections say that tighter regulation, cleaner sources of electricity and higher-mileage vehicles will cut industrial emissions enough by the end of this century that farm emissions will be starved of the other ingredients necessary to create aerosols. A study this January showed that global industrial nitrogen oxide emissions declined from 2005 to 2014, even as farm emissions boomed. (Fast-growing China and India are exceptions.)
