NOVELTY - Integrated method-I of producing ammonia using at least one reactor, comprises: (a) placing at least one electrolyte between each at least one anode and each at least one cathode; (c) feeding gaseous reactants comprising nitrogen sources, carbon sources, and/or hydrogen sources to the reactor; (c) driving anodic and cathodic reactions to produce an electrochemical ammonia synthesis reaction; and (d) producing a catalyzed thermal reaction of nitrogen and hydrogen at ambient pressure.    USE - The method is useful for producing nitrogen fertilizers including ammonium nitrate, urea, ammonia, and urea-ammonium nitrate. No biological data given.    ADVANTAGE - The method is capable of easily and efficiently producing nitrogen fertilizers with improved yield in an economical, industrial and environmentally friendly manner.    DETAILED DESCRIPTION - Integrated method-I of producing ammonia using at least one reactor having at least one cathode gas reaction chamber (6) on a cathode side of the reactor, at least one anode gas reaction chamber (7) on an anode side of the reactor, at least one anode and at least one cathode, comprises: (a) placing at least one electrolyte between each at least one anode and each at least one cathode; (b) feeding gaseous reactants comprising nitrogen sources, carbon sources, and/or hydrogen sources to the reactor; (c) driving anodic and cathodic reactions to produce an electrochemical ammonia synthesis reaction; and (d) producing a catalyzed thermal reaction of nitrogen and hydrogen at ambient pressure.
