In truth, most fertilizer is nitrogen based - synthesized from the air we breath. However it requires a boatload of energy, hence natural gas drives the process. Look up the Haber-Bosch process. Unfortunately a lot of production has been moved overseas. Probably still some capacity in the US. Like rare earth elements and other strategic minerals, its time to re-shore production here to sustain our economy.
