Fertilizers. Chemical analysis. Determination of nitrogen - Method for determination of ammoniacal nitrogen content in the presence of other substances which release ammonia when treated with sodium hydroxide (titrimetric method) Ingestion-build-260237 BS 5421-2 also defines aWhat is BS 5551 4. 1. 4 Ammoniacal nitrogen content in fertilizers about? BS 5551 4. 1. 4 is an international standard that covers the determination of ammoniacal nitrogen content in fertilizers which enables the control of soil acidity for optimum plant growth. BS 5551 4. 1. 4 specifies a method for the determination of the ammoniacal nitrogen content of fertilizers containing other substances, such as urea or urea aldehyde condensates, which release
