Webcan transform (“fix”) atmospheric nitrogen into reactive nitro-gen (Nr) (2) that plants and animals can use. We know that an-other small group of microorganisms can transform (denitrify) Nr back to N 2. Based on the constancy of the N 2 O record, we know that N fixation and denitrification in pre-industrial times were approximately equal (3). WebNitrogen makes plants grow.
