The Nitrogen CycleTechnology, AgFoundation, Stewardship
The ocean's nitrogen cycle is driven by complex microbial transformations, including nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the most abundant form of nitrogen in sea water but only accessible by nitrogen-fixing microbes. Denitrification and nitrification ar...

Much like the concept of the water cycle, the nitrogen cycle is the cyclic movement of nitrogen through the air, land and water. It’s called ageochemical cycle, referring to the fact that geological and chemical factors are both involved. The nitrogen cycle involves the conversion of atmosphe...
nitrogen cycle n. The circulation of nitrogen in nature, consisting of a cycle of chemical reactions in which nitrogen from the atmosphere is fixed in compounds in soil or water, assimilated by plants and animals, released to the soil and water through decomposition, and returned to the atmosphe...
Step 1: Nitrogen Fixation Believe it or not, lightning and bacteria are primarily responsible for turning atmospheric nitrogen into nitrogen living things can use, in a process called nitrogen fixation. Atmospheric nitrogen (N2) is very stable, so it takes an incredible amount of energy to conve...

The nitrogen cycle plays a major role in aquatic nitrogen transformations, including in the terrestrial subsurface. However, the variety of transformations remains understudied. To determine how nitrogen cycling microorganisms respond to different aquife

The nitrogen forms many components like nucleic acids, proteins, amino acids etc. It is the inert gas and is the most abundant gas present in the atmosphere. It plays an important role in the fixation of nitrogen .They play a vital role in the formation of protoplasm. It is present in ...
