From the Sodium nitrate (Chile saltpeter) article:
Sodium nitrate was used extensively as a fertilizer and a raw material for the manufacture of gunpowder in the late 19th century.
Closing because the primary purpose of the reference link is to justify it dropping from Sandstone.
Again, potassium nitrate also drops from sandstone, and sodium nitrate is far worse for gunpowder production than potassium nitrate is. But hey, it's your choice, this doesn't really matter anyway.
I definitely see where you're coming from but I'm going to leave it as is.
Sodium nitrate is not called Saltpeter, Potassium nitrate is. Sodium Nitrate is far less useful for manufacturing gunpowder, and according to http://en.wikipedia.org/wiki/Caliche#Chilean_caliche, Chilean caliche also contains Potassium Nitrate (even though in far lower quantities), so that's fine. Additionally, both Potassium and Sodium nitrate both have almost the same fertilizing properties due to both having the nitrate anion, to justify its other use.
