in nature nitrogen from the atmosphere is converted to ammonia by nitrifying bacteria ammonia is then converted to nitrite and then to nitrate by nitrogen fixing bacteria. nitrate is converted back to nitrogen by denitrifying bacteria
Bacteria convert atmospheric nitrogen into a nitrogen-containing ion that plants can absorb.
Nitrate ion, NO3-
The plant source of Nitrogen is Nitrate. Plants acquire nitrate through the Nitrogen Cycle. Atmospheric Nitrogen is absorbed by Nitrogen-fixing bacteria. The bacteria produce Ammonia which becomes Nitrite. Nitrite becomes Nitrate, the usable form of Nitrogen for plants. Nitrate is assimilated and absorbed by plants. Plants produce amino acids and proteins that are consumed in the food chain. Whatever consumes the proteins and amino acids will eventually die and the decomposition produces ammonia which turns into the atmospheric Nitrogen at the beginning of the cycle.
Ammonium nitrate is used for paddy rice because microbial bacteria decompose ammonium nitrate into nitrogen gas so nitrogen gas does not remain useful for plants.
Starting with ammonium, NH4, which nitrifiying bacteria transform into nitrate (NO3-)and nitrite (NO2-). However, of these compounds, only nitrate is assimilated by plants, making it organic. If not assimilated by plants, denitrifying bacteria take the nitrate and convert it back to atmospheric nitrogen (N2).
Denitrification which is the process of nitrofen returning to the atmosphere which also involes denitrifying bacteria( convert nitrate back into nitrogen gas)

Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
the slaves have to put it in there stew and then they eat it
The nitrogen cycle works better in aerated soil because oxygen is required for the activities of nitrifying bacteria, which convert ammonium (NH4+) into nitrate (NO3-). These nitrifying bacteria are aerobic, meaning they need oxygen to carry out their metabolic processes. In aerated soil, there is better diffusion of oxygen, allowing these bacteria to thrive and efficiently convert ammonium into nitrate.
Bacteria breath in nitrogen and breath out nitrate/
A few plants, especially, legumes (or pulses: pod bearers), of which there is a wide variety; are able to convert nitrogen gas (N2) from the atmosphere to produce Ammonia NH3, a fertilizer. They do this with the symbiotic help of a bacteria (Rhizobium).Lichens, Blue-green algae, and some soil bacteriaalso produce and contribute ammonia to natural ecosystems.Other organisms, chemoautotrophic bacteria, Nitrosomonas, and Nitrobac­ter, convert ammonia to compounds of nitrous oxides culminating in mineral Nitrates (compounds of the form (M)NO3), fertilizers. Examples are Sodium Nitrate (NaNO3) and Potassium Nitrate (KNO3).
Bacteria convert atmospheric nitrogen into a nitrogen-containing ion that plants can absorb.
Nitrate is both an organic & inorganic compound that can be created by decomposers (bacteria) and ester. Since plants grow out of soil, the soil layers contains nitrate bacterias that oxidizes ammonia as well as mix compounds of nitrogen and oxygen allowing plants to receive these materials from plant roots.

The term for bacteria that convert nitrogen into nitrogen compounds is nitrogen-fixing bacteria.
