Fixation of Nitrogen

Fixation of Nitrogen: Nitrogen is essentially an inert element. Under ordinary conditions, the nitrogen of the air does not react with other elements. As most of the nitrogen is present in a free state which cannot be assimilated directly by the living organisms, it has to be converted into its useful compounds by some processes. A …

Symbiotic and Non-Symbiotic Fixation of Nitrogen

Symbiotic and Non-Symbiotic Fixation of Nitrogen: Nitrogen fixation is defined as the phenomenon of the conversion of free nitrogen of the atmosphere into the nitrogenous salts which can readily be absorbed by the plants. The atmosphere contains about 78.1% of nitrogen. The plants and animals are not able to capture the atmospheric nitrogen directly. For its …

Nitrogen Cycle In Nature

Nitrogen Cycle: The cyclic process by which nitrogen element is circulated continuously through the living and non-living components of the biosphere (like atmosphere, soil, water, plants, and animals) is called the nitrogen cycle in nature. In simple words, the circulation of nitrogen in nature is called the nitrogen cycle. Nitrogen gas of the atmosphere is fixed …
