Nitrogen is the largest single component of the Earth's atmosphere (78.082% by volume, 75.3% by weight).

14N is created as part of the fusion processes in stars, and is estimated to be the 7th most abundant chemical element (by mass) in our universe.

Compounds that contain this element have been observed by astronomers, and molecular nitrogen has been detected in interstellar space by David Knauth and coworkers using the Far Ultraviolet Spectroscopic Explorer. Molecular nitrogen is a major constituent of Titan's thick atmosphere, and occurs in trace amounts of other planetary atmospheres.

Nitrogen is present in all living tissues as proteins, nucleic acids and other molecules. It is a large component of animal waste (for example, guano), usually in the form of urea, uric acid, and compounds of these nitrogenous products.

Air: it's 80 percent of the atmosphere. 0.8 * size of the atmosphere / 22 (liters per mol at approximate room pressure and temperature) for the number of moles in the atmosphere

Water: nitrates are one of the major salts in the ocean, often at ~0.1molar. So 0.1 * number of liters of water in all the oceans of the earth for the number of moles in the oceans.

Earth: nitrogen containing minerals are fairly common, and in any place where there was biological activity long ago you will have nitrate minerals. Sodium and potassium nitrates for fertilizers and explosives are dug out of the earth, for example. Chile has huge amounts of it, as do many many other places.

It is most abundent underground in the earth. Sometimes volcanoes and chambers underearth.

In the atmosphere. It forms just under 80% of it.
