The Agricultural Ammonia Indicator (official name: Ammonia Emissions from Agriculture Indicator) estimates the ammonia emissions associated with Canadian agricultural activities from 1981 to 2011. Ammonia is a basic, reactive and toxic gas composed of nitrogen and hydrogen that can have negative impacts on the environment and human health. It is released mainly through naturally occurring processes, such as the breakdown of excreted urea (cattle and pigs) or uric acid (poultry). Ammonia emissions also come from nitrogen fertilizers containing ammonium or urea.
