It is a chemical compound with the chemical formula KNO3.It is found in fertilizers.
You can get potassium nitrate also known as salt peter at pharmisys,as strawberry frtilizer,and as spectricide stump remover other brands don't work. alexh934 6 years agoReply. Potassium Nitrate is the main component of Stump Remover. You can pick it up at Lowe's or Home Depot. Grant's Stump Remover is one of the best stump remover for potassium nitrate. I've used other brands for Sugar/ Potassium Nitrate smoke bombs.  Collecting bat guano from caves used to be the main way to obtain potassium nitrate-also known as saltpeter-but these days there's a much easier way to get what you need to make this basic component of science experiments, fertilizers and gunpowder. 8. Pour off the liquid. After the nitrate crystals form, you'll be left with liquid ammonium chloride. Pour it off and discard so that only the crystals remain in the container. Allow them to dry completely before grinding them down and using your potassium nitrate in science experiments or for other purposes.

Licensed from Columbia University Press. potassium nitrate, chemical compound, KNO 3, occurring as colorless, prismatic crystals or as a white powder; it is found pure in nature as the mineral saltpeter, or niter. Potassium nitrate is prepared commercially by the reaction of potassium chloride with sodium nitrate. When potassium nitrate decomposes (on heating) it releases oxygen; it has been used extensively as the oxygen-supplying component of gunpowder since about the 12th cent. Potassium nitrate is a colorless solid. It dissolves in water. It is a common source of the nitrate ion. Potassium nitrate is a strong oxidizer. It decomposes to potassium nitrite and oxygen when heated. Its pH is almost neutral. It burns with a lilac flame How to make potassium nitrate at home with instant cold packs and sodium-free salt. Sodium-free salt is actually potassium chloride. Instant cold packs contain ammonium nitrate and if the two are mixed potassium nitrate and ammonium chloride are formed in equilibrium.  A common example of an inorganic nitrate salt is potassium nitrate (saltpeter). A rich source of inorganic nitrate in the human body comes from diets rich in leafy green foods, such as spinach and arugula.  Potassium nitrate, derived from nitrate ore and brine, is the active ingredient in Tom's of Maine Natural Sensitive Care SLS-Free Antiplaque Toothpaste.  Potassium nitrate is also called saltpeter and nitrite. It is commonly used to make gun powder and minor explosives, for curing meats and used medically for wounds (when combined with other chemicals). Because potassium nitrate can be found in soils, either by the natural decaying process or by the use of fertilizers, it gets absorbed into vegetables such as spinach, celery and cabbage. Potassium nitrate is a chemical compound with the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3 − . It occurs as a mineral niter and is a natural solid source of nitrogen. 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. Potassium nitrate is used in fertilizers as a source of nitrogen and potassium – two of the macronutrients for plants. When used by itself, it has an NPK rating of 13-0-44.
