The Nitrogen Cycle Let’s begin our discussion of the N cycle in a typical grain crop rotation (corn, wheat, double-crop beans) by considering the plant residue left on the field surface after harvest.

The nitrogen cycle steps are kind of like a currency exchange ... some of which live free in the soil and others of which ...

This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.

Nitrogen gas makes up 78% of Earth’s atmosphere ... which moves the mineral from an area of low concentration in the soil to an area of high concentration, against a concentration gradient ...
