Because:
2No2 + 2NaOH ---> NaNO3 + NaNO2 + H2O
Ammonia nitrate is used as fertilizer; ammonium nitrite is only a contaminant.
Nitrogen fixation
The nitride ion is N3-, three nitrogen atoms bound by three extra electrons to form one molecule of nitrogen.http://en.wikipedia.org/wiki/NitrideThe nitrite ion is NO2-. One nitrogen atom with two oxygen atoms that share an electron to form a molecule of nitrogen dioxide.http://en.wikipedia.org/wiki/NitriteThe nitrate ion is NO32-. The nitrate ion carries a formal charge of negative two, where each oxygen carries a −2/3 charge while the nitrogen carries a +1 charge.http://en.wikipedia.org/wiki/Nitrate
NaNO2, NaNO3
Nitrate- NO3-1 Nitrite- NO2-1 Nitrite has one less oxygen
Ammonia nitrate is used as fertilizer; ammonium nitrite is only a contaminant.

Chemical formulas: NO2 is Nitrite NO3 is Nitrate
Ammonium nitrate and sodium hydroxide form sodium nitrate, water, and ammonia. NH4NO3 + NaOH --> NaNO3 + NH3 + H2O
Ammonium, Nitrite and Nitrate
This is a polyatomic anion. Its called nitrite
This is known as a Nitrate, the 'ate' ending means it has Oxygen in it, the 'Nitr' represents the Nitrogen part.
Nitrate (NO3-) and nitrite (NO2-) are naturally occurring inorganic ions that are part of the nitrogen cycle. Microbial action in soil or water decomposes wastes containing organic nitrogen into ammonia, which is then oxidized to nitrite and nitrate.
Nitrogen fixation
Lead(II) nitrate decomposes into Lead(II) oxide, Nitrogen dioxide and Oxygen:Pb(NO3)2 --Δ--> PbO + NO2 + O2Sodium nitrate decomposes into Sodium nitrite and Oxygen:NaNO3 --Δ--> NaNO2 + O2

I believe you determine Organic Nitrogen by subtracting Ammonia Nitrogen from Total Kjeldahl Nitrogen.
