Soils have an innate ability to supply crops with plant-available nitrogen throughout a growing season, a process known as nitrogen (N) mineralization.This supply of plant-available N comes from soil microbes decomposing organic matter into ammonium (NH 4 ), which is then quickly transformed into nitrate (NO 3-) via nitrification.
The biogeochemical nitrogen cycle is complex with nitrogen Inunobilization is the opposite process, in any attempt to descn'be net nitrogen mineralization.
In summary, soil nitrification was the major process of net soil nitrogen mineralization and soil nitrogen mineralization was not affected by elevational gradient.
release into the atmosphere. It is an anaerobic, heterotrophic microbial process that is important in ecosystem nitrogen cycling. Denitrification removes biologically available nitrogen from the environment, producing relatively inert nitrogen gas, thus playing an important role in mitigating increased human release of nitrogen into the environment.
These forms of nitrogen are incorporated temporarily into the microbial cells in the process of immobilization and inorganic N convert into organic N (Alexander, 1977). Another process is nitrogen mineralization by which organic N is converted to plant-available inorganic forms.

Nitrogen Cycle DenitrificationThis is the reverse process of nitrification. During denitrification nitrates are reduced to nitrites and then to nitrogen gas and ammonia.
