Question

In which way Rhizobium helps in increase soil fertility? Long answer​

Answer 1

Answer:

Rhizobium bacteria helps in nitrogen fixation. They form symbiotic relationship with leguminous plants.

Rhizobium bacteria helps in nitrogen fixation. They form symbiotic relationship with leguminous plants.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. From here, the nitrogen is exported from the nodules and used for growth in the legume. Once the legume dies, the nodule breaks down and releases the rhizobia back into the soil where they can live individually or reinfect a new legume host..

Answer 2

Answer:

Rhizobium helps in nitrogen fixation in plants generally found on luminous plants .

In this process Rhizobium converts atmospheric nitrogen into nitrogen salt .the nitrogen is exported from the nodules and used for growth in the legume.Rhizobia are found in the soil and after infection,Nitrogen fixation helps in fixation of soil fertility and soil productivity Rhizobia are also know as diazotrophic bacteria
