Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. Potassium nitrate is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a blue color. Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r, indicating likely cognation in the Greek nitron, which was Latinised to nitrum or nitrium. Thence Old French had niter and Middle English nitre. By the 15th century, Europeans referred to it as saltpeter and later as nitrate of potash, as the chemistry of the compound was more fully understood. The Arabs called Potassium nitrate "Chinese snow". Potassium nitrate was called "Chinese salt" by the Iranians/Persians or "salt from Chinese salt marshesé". Potassium nitrate has an orthorhombic crystal structure at room temperature, which transforms to a trigonal system at 129 °C (264 °F). Potassium nitrate is moderately soluble in water, but its solubility increases with temperature. The aqueous solution is almost neutral, exhibiting pH 6.2 at 14 °C (57 °F) for a 10% solution of commercial powder. Potassium nitrate is not very hygroscopic, absorbing about 0.03% water in 80% relative humidity over 50 days. Potassium nitrate is insoluble in alcohol and is not poisonous; Potassium nitrate can react explosively with reducing agents, but Potassium nitrate is not explosive on its own.
In Ancient India, saltpeter manufacturers formed the Nuniya caste. Saltpeter finds mention in Kautilya's Arthashastra, which mentions using Potassium nitrate poisonous smoke as a weapon of war, although its use for propulsion did not appear until medieval times. A purification process for potassium nitrate was outlined in 1270 by the chemist and engineer Hasan al-Rammah of Syria in his book al-Furusiyya wa al-Manasib al-Harbiyya. In this book, al-Rammah describes first the purification of barud by boiling Potassium nitrate with minimal water and using only the hot solution, then the use of potassium carbonate to remove calcium and magnesium by precipitation of their carbonates from this solution, leaving a solution of purified potassium nitrate, which could then be dried. This was used for the manufacture of gunpowder and explosive devices. The terminology used by al-Rammah indicated a Chinese origin for the gunpowder weapons about which he wrote.
A major natural source of potassium nitrate was the deposits crystallizing from cave walls and the accumulations of bat guano in caves. Extraction is accomplished by immersing the guano in water for a day, filtering, and harvesting the crystals in the filtered water. Traditionally, guano was the source used in Laos for the manufacture of gunpowder for Bang Fai rockets. In West African cuisine, potassium nitrate (saltpetre) is widely used as a thickening agent in soups and stews such as okra soup and isi ewu. Potassium nitrate is also used to soften food and reduce cooking time when boiling beans and tough meat. Saltpetre is also an essential ingredient in making special porridges, such as kunun kanwa literally translated from the Hausa language as 'saltpetre porridge'. In the Shetland Islands (UK) Potassium nitrate is used in the curing of mutton to make reestit mutton, a local delicacy. Potassium Nitrate is a crystalline salt, Potassium Nitrate; a strong oxidizer used especially in making gunpowder, as a fertilizer, and in medicine.

Potassium nitrate has a role as a fertilizer. Potassium nitrate is a potassium salt and an inorganic nitrate salt. Potassium nitrate (Potassium Nitrate) is a soluble source of two major essential plant nutrients. It’s commonly used as a fertilizer for high-value crops that benefit from nitrate (NO₃-) nutrition and a source of potassium (K+) free of chloride (Cl⁻). Manufacturers typically make potassium nitrate fertilizer (sometimes referred to as nitrate of potash or NOP by reacting potassium chloride (KCl) with a nitrate source. Depending on the objectives and available resources, the nitrate may come from sodium nitrate, nitric acid or ammonium nitrate. The resulting Potassium Nitrate is identical regardless of the manufacturing process. Potassium nitrate is commonly sold as a water-soluble, crystalline material primarily intended for dissolving and applying with water or in a prilled form for soil application. Traditionally, this compound is known as saltpeter. Growers value fertilizing with Potassium Nitrate especially in conditions where a highly soluble, chloride-free nutrient source is needed. In such soils, all of the N is immediately available for plant uptake as nitrate, requiring no additional microbial action and soil transformation.
Growers of high-value vegetable and orchard crops sometime prefer to use a nitrate-based source of nutrition in an effort to boost yield and quality. Potassium nitrate contains a relatively high proportion of K, with an N to K ratio of approximately one to three. Many crops have high K demands and can remove as much or more K than N at harvest. Applications of Potassium Nitrate to the soil are made before the growing season or as a supplement during the growing season. A diluted solution is sometimes sprayed on plant foliage to stimulate physiological processes or to overcome nutrient deficiencies. Foliar application of K during fruit development advantages some crops, since this growth stage often coincides with high K demands during the time of declining root activity and nutrient uptake. Potassium Nitrate’s also commonly used for greenhouse plant production and hydroponic culture.
Both N and K are required by plants to support harvest quality, protein formation, disease resistance and water-use efficiency. Therefore, to support healthy growth, farmers often apply Potassium Nitrate to soil or through the irrigation system during the growing season. Potassium nitrate accounts for only a small portion of the global K fertilizer market. Potassium Nitrate’s primarily used where its unique composition and properties can provide specific benefits to growers. Further, it’s easy to handle and apply, and is compatible with many other fertilizers, including specialty fertilizers for many high-value specialty crops, as well as those used on grain and fiber crops. The relatively high solubility of Potassium Nitrate under warm conditions allows for a more concentrated solution than for other common K fertilizers. However, farmers must carefully manage the water to keep the nitrate from moving below the root zone. Potassium nitrate has long been used for fireworks and gunpowder. .
