Mainly used as a fertilizer. When applied as plant food, it temporarily increases the soil pH (more basic) , but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium.

It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment.
