Triazone

This is a liquid nitrogen fertiliser which is produced from the reaction processes of urea, formaldehyde and ammonia. It contains at least 25% to 28% N. It should not be applied with either ammonium-based nitrogen fertilisers as this may cause volatilization of the ammonia, or with fertilisers containing ferrous iron because of iron oxidation, making it unavailable to the plant. It is also referred to as Urea-Triazone (UT).
