Nitrogen (N<sub>2</sub>) is a material which can be obtained via [[ISRU|in situ resource utilization]] on [[Mars]]. It occurs naturally in the [[Martian atmosphere]] in extractable quantities. It is also a soluble gas.

Some plants require free nitrogen, although most can be supported by aqueous solutions of nitrogen compounds. Nitrogen, the primary component of [[Earth]]'s atmosphere, can also be used as an inert filler for the cabin atmosphere.

Nitrogen is relatively unreactive, and can be used to quench less energetic reactions. Liquid nitrogen is a very effective cryogenic refrigerant. Many useful compounds have a nitrogen chemical content, inclusing several important oxidizers and reducing agents.

==Storage of Nitrogen==

Small amounts of nitrogen can be stored as pressurized gas. Larger amounts must be stored as a cryogenic liquid. Nitrogen can also be produced chemically from ammonia and other chemical compounds; however, since it is readily available from the Martian atmosphere, it may be more viable for a Martian settlement to use free nitrogen to produce these chemicals rather than the other way around.
