Niter is a Renaissance Era Strategic Resource in Civilization VI. It is required in order to build the Musketman and Bombard units.
Niter is found on a variety of terrains, always on flatland.
Strategy
Niter is a mid-game resource that is often found in rather cumbersome locations (such as Tundra regions), but it is essential for furthering military progress in the game. It is a requirement for producing the major siege and melee units of its era, and, as its influence can reach even into the Modern Era, it can be considered highly valuable for warfare.
Niter additionally offers equivalent resource boosts as the Horse to 
Production and 
Food, so it is generally recommended to take advantage of its appearance.
Civilopedia Entry
Better known as saltpeter, niter is the mineral form of potassium nitrate. Although known for millennium, it didn’t become important until the Chinese figured out it could be combined with sulfur to make gunpowder in the mid-1st Century AD. And gunpowder is really good for making fireworks and blowing things up. Niter is also useful as a fertilizer and food preservative, but few people remember that.
