Emission factors affecting soil NH3 losses from mineral fertilizers


Ammonia (NH3) emissions from agricultural soil has been a concern and principal investigative issue, especially in slurry/manure use and management practices. The amount of soil N loss due to NH3 volatilization varies depending on soil conditions, fertilizer, fertilization method, climate, etc. Ma et al (2020) reported that average global NH3 emissions from synthetic N fertilizer is about 13%, with Europe contributing 7.1% of total global NH3 emissions. This review focuses on soil-derived NH3 emissions from mineral fertilizer and the main factors influencing applied N losses, which is less represented in recent literature. Most literature found focuses on NH3 emissions from urea fertilizer and applied urea with an inhibitor. Details from all articles and results discussed in this review, can be viewed in the link below.
