The Earth's atmosphere is composed of about 78 percent nitrogen, making it the most abundant gas in the atmosphere. This nitrogen is essential for plant growth and is also found in proteins and DNA.
Nitrogen in Earth's atmosphere is believed to have come from volcanic outgassing billions of years ago, as well as from the breakdown of ammonia in the early atmosphere through photochemical reactions. This nitrogen has been recycled through various natural processes, such as plant respiration and decomposition, contributing to the stable composition of nitrogen in the atmosphere.
During nitrogen fixation, certain bacteria convert atmospheric nitrogen into a form that plants can use, like ammonia. This process helps make nitrogen available for plant growth, which then enters the food chain as animals consume plants. Overall, nitrogen fixation is essential for maintaining the balance of nitrogen in ecosystems and supporting plant growth.

Nitrogen from the atmosphere primarily enters the soil through a process called nitrogen fixation, which is carried out by certain bacteria and archaea that can convert atmospheric nitrogen (N₂) into ammonia (NH₃). This ammonia can then be further transformed into nitrates (NO₃⁻) by nitrifying bacteria. Plants absorb these nitrates and ammonium ions through their roots, allowing them to utilize nitrogen for growth and development.
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.
Nitrogen enters the soil through the application of nitrogen-rich fertilizers and through the decomposition of organic matter, such as plant residues and animal manure. Nitrogen-fixing bacteria in legume plant roots also play a role in transferring nitrogen from the atmosphere to the soil.
Before nitrogen enters a plant, it typically first undergoes a process called nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃) by certain bacteria in the soil or in symbiotic relationships with legumes. This ammonia can then be transformed into nitrates (NO₃⁻) through nitrification, a process carried out by nitrifying bacteria. The resulting nitrates and ammonium ions are taken up by plant roots from the soil, allowing plants to utilize nitrogen for growth and development.
The free nitrogen produced by bacteria is converted into a form that plants can absorb, which then enters the food chain when animals consume these plants. Eventually, the nitrogen returns to the soil through decomposition of plant and animal matter, completing the nitrogen cycle.
The nitrogen goes into the soil and then into the atmosphere through denitrification ;)
