Nitrogen- fixing bacteria consume nitrogen in the air and change it into a for that plants can use.
Not all plants rely upon symbiotes to fix atmospheric N, but those that do do so because they lack biochemical pathways for accomplishing this task on their own.
explain the role of nitrifying bacteria in making nitrate available to 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).

explain the role of nitrifying bacteria in making nitrate available to plants?
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 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.
They have mutualistic relationships with fungi and bacteria that can split atmospheric nitrogen into a form that is usable by the plants.
Bacteria will seek out Nitrate as an oxygen source before using sulfate, braking the sulfide production chain in wastewater. Calcium Nitrate is one Nitrate based chemical, others include Nitrate of Soda and Potassium Nitrate.

Nitrates are found in man-made fertilizers. They are also found in soil after the nitrogen fixating bacteria converts Nitrite to Nitrate (Nitrogen Cycle) which can be utilized by plants and consumed by the consumers.
The ion nitrate used in curing is converted to nitrite by enzymes or bacteria. The nitrite then prevents the bacteria from growing.
