Cyanobacteria can affix atmospheric nitrogen (N2).

Nitrification
plants absorb amonnia or nitrate
Clover peas lupins.
The process is called nitrogen fixation. Bacteria in the soil convert atmospheric nitrogen into ammonia, which plants can then use as a nutrient. Lightning can also contribute to this process by converting nitrogen gas into nitrates that can be absorbed by plants.
Nitrogen fixing bacteria, such as Rhizobium.
The Marshall Plan.
Diazotroph is the common name for nitrogen-fixing bacteria and micro-organisms.Specifically, the term designates organisms that are capable of turning atmospheric nitrogen into more usable forms, such as ammonia. It includes such soil-dwellers as Frankia genus members living symbiotically with actinorhizal (beech, cucurbit and rose-related orders) plants and Rhizobia genus members living symbiotically with leguminous (bean-related order) plants. Cyanobacteria living symbiotically with lichens and liverworts also number among the diazotrophs of greater name recognition.
De-nitrification
nitrogen trihydride? no idea. i need help with this too. im pretty sure its Azane
