Sodium nitrate is a readily available source of the nitrate anion (NO3−), which is useful in several reactions carried out on industrial scales for the production of fertilizers, pyrotechnics, smoke bombs and other explosives, glass and pottery enamels, food preservatives (esp. meats), and solid rocket propellant.
Sodium nitrate has been mined extensively for these purposes.
The largest accumulations of naturally occurring sodium nitrate are found in Chile and Peru, where nitrate salts are bound within mineral deposits called caliche ore.
Sodium nitrates accumulate on land through marine-fog precipitation and sea-spray oxidation/desiccation followed by gravitational settling of airborne NaNO3, KNO3, NaCl, Na2SO4, and I, in the hot-dry desert atmosphere.
For more than a century, the world supply of the compound was mined almost exclusively from the Atacama desert in northern Chile until, at the turn of the 20th century, German chemists Fritz Haber and Carl Bosch developed a process for producing ammonia from the atmosphere on an industrial scale (see Haber process). With the onset of World War I, Germany began converting ammonia from this process into a synthetic Chilean saltpeter, which was as practical as the natural compound in production of gunpowder and other munitions. By the 1940s, this conversion process resulted in a dramatic decline in demand for sodium nitrate procured from natural sources.
Chile still has the largest reserves of caliche and there it used to be called white gold.
Sodium nitrate, potassium nitrate, sodium sulfate and iodine are all obtained by the processing of caliche.
The former Chilean saltpeter mining communities of Humberstone and Santa Laura were declared UNESCO World Heritage sites in 2005.

Sodium nitrate has been used in meat curing for centuries.
Sodium nitrate has no antioxidant activity but becomes functional on reduction to nitrite.
The important functions of sodium nitrite include stabilization of meat colour, texture improvement, development of the characteristics cured meat flavour, elimination of the problem of warmed over flavour and antimicrobial activity.
Nitrites probably function as metal chelators may form nitroso compounds that have antioxidants properties and convert the heme proteins into stable nitric oxide forms.
Because sodium nitrate is readily and entirely soluble in water, and because the nitrate ion is not absorbed by soil colloids, it should be applied for early utilization by the crop following application.
This principle is applicable to all nitrate fertilizers.
The loss of nitrates in drainage water is especially severe when nitrates are applied to sands and particularly sands with open subsoils, from which they may be leached easily.
Larger quantities of sodium nitrate may be applied to clays than the sands, but even in such cases the application of quantities greater than that which the crop is in position to utilize within a reasonable length of time should be avoided.
When large amounts are to be used it will be found best to apply sodium nitrate in two or more applications.
Such a practise will minimize the loss of nitrogen by leaching, and at the same time will avoid injuring plant roots by applying excessive quantities of soluble salt at one time.
The first application may be broadcast or applied in the drill before plating, and the second and later applications may be applied as side dressings or top dressings.
Top dressings of sodium nitrate often appear to be more effective during cool than during warm seasons.

Sodium nitrate is manufactured by two methods.
In the first, known as the Guggenheim method, the fertilizer is extracted from a mined product, called caliche, mined mostly in Chile; hence the name (Chilean saltpeter or Chilean nitrate).
Sodium nitrate is dissolved in warm water and then cooled to 0°C to produce sodium nitrate crystals, which are circulated through heat exchangers.
