Nitrogen is essential element for plants and is found in abundance as atmospheric nitrogen. But most plants unable to use it. Why is it so and in what form do plants utilize them? |

Answer» Most plants cannot use it because atmospheric nitrogen is inert in its nature. Nitrogen fixers in soil can convert nitrogen gas into nitrates or nitrite or ammonium forms. These compounds enter the plants as nutrients through the roots and are assimilated as organic nitrogen. |
