Biological nitrogen fixation is a much more important process in the nitrogen cycle of the oceans than previously thought. Further, nitrogen fixation may have an influence on the capacity of the oceans to sequester carbon. A greater diversity of marine nitrogen fixers has also been uncovered but ...
上文“The pulses are cheap and great alternative to meat.”(豆类便宜且是肉的很好的替代品)这句话说明了豆荚的好处,下文“Pulse crops are able to pull nitrogen from the atmosphere into the soil.This process is called nitrogen fixation and provides a natural fertilizer(肥料),which is available ...

The first process of the nitrogen cycle isnitrogen fixation. This is the process of converting atmospheric nitrogen into usable compounds like ammonia, nitrates, nitrites, etc. This is done via several activities. The energy generated during lightning causes oxygen and nitrogen to combine to form ni...
What is the role of nitrogen in eutrophication? What is the purpose of warfarin? What is the role of nitrate in microbial metabolism? What is an amniotomy, and what important nursing roles go along with it? What is the role of chemical mediators of inflammation?
2. Nitrogen Cycle Nitrogen is also an essential component of life. Nitrogen cannot be directly utilised by living organisms and has to be converted to other forms. By the process of nitrogen fixation, nitrogen-fixing bacteria fix atmospheric nitrogen to ammonia and nitrifying bacteria convert ammonia...
43、bout nitrogen-fixation - the process by which plants can be made to “fix” their own nitrogen, thus reducing the need for fertilizer? scientists all over the world are now pursuing this prospect in the hope of combating famine. how much is known about the revolutionary changes being mad...
