What i am reffering to is microbial decomposition/ fixation which occurs both in the atmosphere (water) and substrate in aquatic environments.What? why wouldn't it happen on land too. that doesn't make sense. Please clarify and help me understand (and avoid another fish water incedent) I learned as a kid that lightning brings/releases nitrogen into the air/rain. thats why nothing makes your lawn greener than real rain

The nitrogen molecule (N[SUB]2[/SUB]) is quite inert. To break it apart so that its atoms can combine with other atoms requires the input of substantial amounts of energy.
Three processes are responsible for most of the nitrogen fixation in the biosphere:
Atmospheric Fixation
- atmospheric fixation by lightning
- biological fixation by certain microbes — alone or in a symbiotic relationship with some plants and animals
- industrial fixation
The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.
Atmospheric nitrogen fixation probably contributes some 5– 8% of the total nitrogen fixed.
On land it is primarily in the substrate (dirt).
