|Ammonia knives for subsoil application|
Ammonia will rapidly react with soil water to form ammonium (NH4+), which is retained on the soil cation exchange sites. Ammonia is sometimes dissolved in water to produce “aqua ammonia”, a popular liquid N fertilizer. Aqua ammonia does not need to be injected as deeply as NH3, which provides benefits during field application and has fewer safety considerations. Aqua ammonia is frequently added to irrigation water and used in flooded soil conditions.
