There are different nitrogen gases that come out of the soil. Ammonium, for example, will volatilise up into the atmosphere, fossil fuel burning will release nitrogen into the atmosphere and lightning will convert dinitrogen gas in the atmosphere to water-soluble forms of nitrogen. And when it rains, the rain will strip that nitrogen out of the atmosphere and deposit it onto the surface of the land.
