But they cannot directly utilize the nitrogen gas (N 2 ) in the air. To produce nitrogen fertilizers , it is necessary to “ fix ” the nitrogen in a form the plants can use. 3 FIXING NITROGEN BY THE HABER PROCESS Fritz Haber deduced the optimal conditions for reacting N 2 and H 2 to produce NH 3 (ammonia).
