Ammonia is a major source of air pollution from fertilizers, as it can react with other compounds in the atmosphere to form harmful pollutants such as particulate matter and ozone.

Volatilization is the primary mechanism by which fertilizers contribute to air pollution, as it involves the release of gaseous compounds from fertilizers into the atmosphere.

Urea is the type of fertilizer most commonly associated with ammonia emissions, as it contains a high concentration of nitrogen in the form of urea, which can be easily converted to ammonia.

Soil pH is the primary factor influencing the rate of ammonia volatilization from fertilizers, as higher pH levels favor the conversion of ammonium ions to ammonia gas.

All of the above practices are commonly used to reduce ammonia emissions from fertilizers, as they help to minimize the amount of ammonia that is released into the atmosphere.

Denitrification is the primary mechanism by which fertilizers contribute to nitrous oxide emissions, as it involves the conversion of nitrate and nitrite ions to nitrous oxide gas.

Ammonium nitrate is the type of fertilizer most commonly associated with nitrous oxide emissions, as it contains a high concentration of nitrogen in the form of nitrate, which can be easily converted to nitrous oxide.

Soil moisture is the primary factor influencing the rate of nitrous oxide emissions from fertilizers, as higher moisture levels favor the denitrification process.

All of the above practices are commonly used to reduce nitrous oxide emissions from fertilizers, as they help to minimize the amount of nitrous oxide that is released into the atmosphere.

Volatilization is the primary mechanism by which fertilizers contribute to sulfur dioxide emissions, as it involves the release of sulfur dioxide gas from fertilizers into the atmosphere.

Superphosphate is the type of fertilizer most commonly associated with sulfur dioxide emissions, as it contains a high concentration of sulfur in the form of sulfate, which can be easily converted to sulfur dioxide.

Soil pH is the primary factor influencing the rate of sulfur dioxide emissions from fertilizers, as higher pH levels favor the conversion of sulfate ions to sulfur dioxide gas.

All of the above practices are commonly used to reduce sulfur dioxide emissions from fertilizers, as they help to minimize the amount of sulfur dioxide that is released into the atmosphere.

Air pollution from fertilizers can cause a range of health effects, including respiratory problems, cardiovascular problems, and cancer.

Air pollution from fertilizers can cause a range of environmental effects, including acid rain, eutrophication, and climate change.
