Nitrogen Cycle (4)

In this article we will discuss Nitrogen Cycle (4)

Nitrogen may be removed from the nitrates in the soil by denitrifying bacteria, and returned to the atmospheric reservoir, from which it can be released again by either nitrogen-fixing bacteria or electrification by lighting. In the latter case, the energy of a lightning bolt passing through the atmosphere binds nitrogen and oxygen together into nitrate, which precipitate onto the soil from the air during electrical storms.
