Question

how rhizobium help in nitrogen fixation

Answer 1

rhizobium bacteria present in the root nodules of leguminous plants covert atmospheric nitrogen into usable form and thus help in nitrogen fixation as no more nitrogen is added to replenish the nutritional value of the soil

Answer 2

Hi !

Here's the answer to your question :

Rhizobia is “the group of soil bacteria that infect the roots of legumes to form root nodules”. Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen.

Hope this helps !!!
