Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter or saltpetre.Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks.otassium nitrate is used in fertilizers as a source of nitrogen and potassium â two of the macronutrients for plants. When used by itself, it has an NPK rating of 13-0-44.
It is a readily available source of the nitrate anion (NO 3 â), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics and smoke bombs, glass and pottery enamels, food preservatives (esp. meats), and solid rocket propellant. mixture of sodium nitrate, calcium nitrate and potassium nitrate is used as energy storage material in prototype plants, such as Andasol Solar Power Station and the Archimedes project.
