-Meat processing:
E252 (Potassium nitrate) has been a common ingredient of salted meat since antiquity or the Middle Ages.
The widespread adoption of nitrate use is more recent and is linked to the development of large-scale meat processing.
The use of E252 (Potassium nitrate) has been mostly discontinued because of slow and inconsistent results compared to sodium nitrite compounds such as "Prague powder" or pink "curing salt".

E252 (Potassium nitrate)’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⁻).
PRODUCTION:
Manufacturers typically make E252 (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 E252 (Potassium nitrate) is identical regardless of the manufacturing process.
E252 (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.
AGRICULTURAL USES:
Growers value fertilizing with KNO₃ 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.
E252 (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 KNO₃ 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.
E252 (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 KNO₃ to soil or through the irrigation system during the growing season.
E252 (Potassium nitrate) accounts for only a small portion of the global K fertilizer market.
E252 (Potassium nitrate)’s primarily used where its unique composition and properties can provide specific benefits to growers.
Further, E252 (Potassium nitrate)’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 KNO₃ 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.
NON-AGRICULTURAL USES:
E252 (Potassium nitrate) has long been used for fireworks and gunpowder.
E252 (Potassium nitrate)’s now more commonly added to food to maintain the quality of meat and cheese.
Specialty toothpastes often contain KNO₃ to alleviate tooth sensitivity.
A mixture of KNO₃ and sodium nitrate (NaNO₃) is used for storing heat in solar energy installations.

E252 (Potassium nitrate)s common names include saltpetre (from Medieval Latin sal petrae: "stone salt" or possibly "Salt of Petra"), American English salt peter, Nitrate of potash and nitre.
The name salt peter is also applied to sodium nitrate.
E252 (Potassium nitrate) is the oxidizing (oxygen-supplying) component of black powder.
Prior to the large-scale industrial fixation of nitrogen through the Haber process, a major source of E252 (Potassium nitrate) was the deposits crystallising from cave walls or the drainings of decomposing organic material.
Dung-heaps were a particularly common source: ammonia from the decomposition of urea and other nitrogenous materials would undergo bacterial oxidation to produce nitrate.
E252 (Potassium nitrate) was and is also used as a component in some fertilizers.
When used by itself as a fertilizer, it has an NPK rating of 13-0-44 (indicating 13%, 0%, and 44% of nitrogen, phosphorus, and potassium, by mass, respectively).
MANUFACTURE:
Historically, nitre-beds were prepared by mixing manure with either mortar or wood ashes, common earth and organic materials such as straw to give porosity to a compost pile typically 1.5 metres high by 2 metres wide by 5 metres long.
The heap was usually under a cover from the rain, kept moist with urine, turned often to accelerate the decomposition and leached with water after approximately one year.
The liquid containing various nitrates was then converted with wood ashes to E252 (Potassium nitrate)s, crystallized and refined for use in gunpowder.
Today, most E252 (Potassium nitrate) comes from the vast deposits of sodium nitrate (NaNO3, nitratine) in the Chilean deserts.
The sodium nitrate is purified and then reacted in solution with potassium chloride (KCl, sylvite), from which the less-soluble E252 (Potassium nitrate) is precipitated out.
APPLICATION:
One of the most useful applications of E252 (Potassium nitrate) is in the production of nitric acid, by adding concentrated sulfuric acid to an aqueous solution of E252 (Potassium nitrate), yielding nitric acid and potassium sulfate which are separated through fractional distillation.
