WebMay 8, 2012 · Nitrogen gas can be fixed in three ways. Atmospheric fixation. This occurs spontaneously by lightning; only a small amount (5–8%) is fixed this way. Lightning allows nitrogen and oxygen to combine to produce various oxides of nitrogen. These are carried by the rain into the soil where they can be used by plants. Industrial fixation. Web2 days ago · Nitrogenase, the key enzyme for biological nitrogen fixation, is an evolutionary singularity, as only one mechanism capable of catalyzing the reduction of atmospheric N 2 into fixed nitrogen is known to have evolved.
