Hey friend ^_^
Here is your answer:
> Plants use nitrogen only in the form of nitrates which they absorb from the soil through roots. <
These nitrates are fixed in the soil by the bacteria by nitrification.
Hope it helps u!

Thanks for the question!
It is definitely a very interesting question to solve and do some brainstorming.
**************************************************
Plants absorb nitrogen from the soil and water mostly in the form of
or 
through the root hairs present in plants from which maximum water absorption and collection of mineral nutrients and water happen.
The process of Ammonification and Nitrification are generally performed via Nitrogenous excretion and various Nitrogenous substances (example, proteins) of dead organisms which are further acted upon by decomposes (for an example, Bacillus ramosus, Bacillus vulgaris). They are first formed by amino acids and then ammonia. The process is called and known as Ammonification, this happens when some bacterium (given above) or decomposes like fungi act upon organic nitrogen and convert it to Ammonium ion or NH4+; the reaction is as follows:
Proteins + H2O (Presence of water) 》R-NH2 (R = alkyl group, NH2 = Amide or Amidogen or amino group or amine) 》[in the presence of positive water molecules] ROH (Organic acid) + NH3 (Ammonia)
Ammonia is oxidised by nitrite bacteria to produce the toxic component of plants called as Nitrite, some of the bacterium used are, Nitrosomonas, Nitrosococcus, etc. Nitrite is then further oxidised by nitrate bacteriums, such as, Nitrobacter, etc. and some fungi, such as, Penicillium to ultimately forming the much needed nitrates, the reactions are as follows;
NH4+ (Ammonium ion) + 2O2 (Oxygen molecules) 》NO2- (Nitrogen oxide ion) + 2H2O (Water molecules) + Energy released
2NO2- (Nitrogen oxide ion) + O2 (Oxygen molecules) 》2NO3- (Nitrate ions) + Energy released.
Furthermore the reactions of Nitrate Assimilation by which nitrates and nitrites are broken down to produce Ammonia. Denitrification occurs at last to make the cycle continuous and form Molecular Nitrogen in air or gaseous form again including Nitrogen oxides.
