The nitrogen cycle is arguably the second most important cycle, after the carbon cycle, to living organisms. Nitrogen is essential to plant growth, and therefore is a significant contributor to the human food chain, but its presence in the environment is strongly influenced by anthropogenic activities. nitrogen fixation the utilization of atmospheric nitrogen in the synthesis of AMINO ACIDS by some bacteria. Such bacteria can be free-living (e.g. Azotobacter, an aerobe; Clostridium, an obligate anaerobe) while others (e.g. Rhizobium) live in association with plants, occupying swellings in the root called root nodules.

Hence, legumes are among the best sources of plant protein. When a legume plant dies in the field, for example following the harvest , all of its remaining nitrogen, incorporated into amino acids inside the remaining plant parts, is … Process of the Nitrogen Cycle Fixation. Nitrogen in its pure gas form is unusable. It is converted through a process called Fixation where N2 + 3 H2 -> 2 NH3 (ammonia). Fixation can happen in three ways. Nitrogen disperses in the earth’s soil and bacteria transforms it to ammonium ions (NH4+) which is accessed by plants. Nitrates were long the main source of nitrogen for industrial use (at present, the commercial synthesis of ammonia from hydrogen and atmospheric nitrogen is of primary importance in nitrogen fixation). Small amounts of bound nitrogen occur in coal (1–2.5 percent) and petroleum (0.02–1.5 percent), as well as in river, sea, and ocean water. 2008-11-17 · Nitrogen fixation is the process by which nitrogen is taken from its natural, relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds (such as amNitrogen fixation is performed naturally by a number of different prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria.
