How do plants get their nutrients?

Nitrogen is a major part of proteins in plant tissue and a component of chlorophyll, the green pigment needed for photosynthesis. Although air is 78 percent nitrogen gas, plants must take up nitrogen compounds from the soil. Ammonia, which contains nitrogen and hydrogen, and nitrate, containing nitrogen and oxygen, can be absorbed by plant roots

EPA Information - Photochemical smog — what it means for us

Nitrogen is not in the actual fuels used in motor vehicles or power stations; it is introduced from the air when combustion occurs. Using less air in combustion can reduce emissions of nitrogen oxides. Temperature also has an effect on emissions—the lower the temperature of combustion, the lower the production of nitrogen oxides.
