Nitrate (NO3) is reduced during the microbially aided process of denitrification, which results in the production of molecular nitrogen (N2) after a succession of intermediate gaseous nitrogen oxide products.
Nitrate is transformed into nitrogen gas during denitrification.
As a result, it recycles atmospheric nitrogen and eliminates bioavailable nitrogen.
Dinitrogen gas is the end result of denitrification. Other intermediate nitrogen gaseous forms do, however, also exist.
Maintaining a minimal concentration of nitrate is necessary to enable plant growth while minimizing denitrification.
This can be done by implementing controlled-release fertilizer treatments, fertigation, divided fertilizer applications, etc.
