=== Fertiliser ===
In the US {{As of|2019|lc=y}}, approximately 88% of ammonia was used as [[fertiliser]]s either as its salts, solutions or [[anhydrous]]ly.<ref name="USGS-2020">{{cite web |url=https://pubs.usgs.gov/periodicals/mcs2020/mcs2020.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://pubs.usgs.gov/periodicals/mcs2020/mcs2020.pdf |archive-date=2022-10-09 |url-status=live |title=Mineral Commodity Summaries 2020, p. 117 – Nitrogen |publisher=[[USGS]] |year=2020 |access-date=12 February 2020}}</ref> When applied to soil, it helps provide increased yields of [[crop]]s such as [[maize]] and [[wheat]].<ref>{{cite journal |last1=Lassaletta |first1=Luis |last2=Billen |first2=Gilles |last3=Grizzetti |first3=Bruna |last4=Anglade |first4=Juliette |last5=Garnier |first5=Josette |title=50-year trends in nitrogen use efficiency of world cropping systems: the relationship between yield and nitrogen input to cropland|journal=Environmental Research Letters |date=2014 |volume=9 |issue=10 |pages=105011 |doi=10.1088/1748-9326/9/10/105011 |language=en |issn=1748-9326 |bibcode=2014ERL.....9j5011L |doi-access=free}}</ref> 30% of agricultural nitrogen applied in the US is in the form of anhydrous ammonia, and worldwide, 110&nbsp;million tonnes are applied each year.<ref>{{cite news|url=https://www.washingtonpost.com/national/health-science/anhydrous-ammonia-fertilizer-abundant-important-hazardous/2013/04/18/c2d4c69c-a85a-11e2-a8e2-5b98cb59187f_story.html|title=Anhydrous ammonia fertilizer: abundant, important, hazardous|newspaper=Washington Post|author=David Brown|date=18 April 2013|access-date=23 April 2013}}</ref>
Solutions of ammonia ranging from 16% to 25% are used in the [[Industrial fermentation|fermentation]] industry as a source of nitrogen for microorganisms and to adjust pH during fermentation.<ref>{{Cite web|title=Applications of Anhydrous Ammonia and Aqueous Ammonia|url=https://www.mysoreammonia.com/applications/|access-date=2022-02-02|website=www.mysoreammonia.com}}</ref>
