Reduction of Dinitrogen to Ammonia (IMAGE) Utah State University Caption All living things require nitrogen for survival, but the world depends on only two known processes to break nitrogen's ultra-strong bonds to allow conversion to a form humans, animals and plants can consume. One is a natural, bacterial process on which farmers have relied since the dawn of agriculture. The other is the century-old Haber-Bösch process, which revolutionized fertilizer production and spurred unprecedented growth of the global food supply.
