Diammonium Hydrogen Phosphate is an exceptionally versatile material. It is primarily known and used as a fertiliser - it temporarily increases the soil pH, which then lowers over time as nitrification of the ammonium occurs. It is also heavily used in the baking industry as a synergistic ingredient in breadmaking - providing phosphorus and nitrogen which are vital for yeast cell growth. It is for this reason that it is also used in the winemaking industry! It is also used widely as a fire retardant in fighting forest fires, while other documented uses include being a cigarette additive, a sugar purification agent, a flux for soldering and a control for the precipitation of dyes on wool!
