WHAT DOES NITROGEN FIXATION MEAN IN ENGLISH?
Nitrogen fixation
Nitrogen fixation is a process by which nitrogen in the atmosphere is converted into ammonium. Atmospheric nitrogen or molecular nitrogen is relatively inert: it does not easily react with other chemicals to form new compounds. The fixation process frees up the nitrogen atoms from their diatomic form to be used in other ways. Nitrogen fixation, natural and synthetic, is essential for all forms of life because nitrogen is required to biosynthesize basic building blocks of plants, animals and other life forms, e.g., nucleotides for DNA and RNA and amino acids for proteins. Therefore nitrogen fixation is essential for agriculture and the manufacture of fertilizer. It is also an important process in the manufacture of explosives. Nitrogen fixation occurs naturally in the air by means of lightning. Nitrogen fixation also refers to other biological conversions of nitrogen, such as its conversion to nitrogen dioxide. Microorganisms that can fix nitrogen are prokaryotes called diazotrophs. Some higher plants, and some animals, have formed associations with diazotrophs.
Definition of nitrogen fixation in the English dictionary
The definition of nitrogen fixation in the dictionary is the conversion of atmospheric nitrogen into nitrogen compounds by certain bacteria, such as Rhizobium in the root nodules of legumes. Other definition of nitrogen fixation is a process, such as the Haber process, in which atmospheric nitrogen is converted into a nitrogen compound, used esp for the manufacture of fertilizer.
