Processes of the Nitrogen Cycle. Nitrogen fixation is the process of converting the atmospheric nitrogen (N 2) into biological state nitrogen. It is the first process of making nitrogen available for plants. It is defined as an anaerobic (without oxygen) process that catalyzes the reduction of atmospheric nitrogen (N 2) into ammonia (NH 3 ).
