Earth's vast reservoir is in it's atmosphere which is roughly 79% nitrogen.
Yes, soil does contain nitrogen.
Legumes fix nitrogen in the soil.
Soil.
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
the soil is a major reservoir for ammonia and other nitrogen containing compounds.
The atmosphere is the main reservoir of nitrogen in the biosphere.
