Question

Explain What is the Use of Rhizobium Bacteria?

Answer 1

Rhizobium bacteria lives in the root nodules of leguminous plants.
Function....
Plants need nitrogen which is available in the atmosphere in abundance. But plants cannot consume nitrogen directly from the atmosphere. Therefore, Rhizobium bacteria converts atmospheric nitrogron into a form that can be consumed by plants. Plants take in this nitrogen through their roots for their functioning.....

Answer 2

Rhizobia bacteria are a group of soil based microorganisms (SBO's) which establish symbiotic relationships with legumes. These SBO's form nodules on the roots of the legumes and provide nitrogen to the plants. In return, the plants provide carbon and energy for the SBO's.

Nitrogen is vital for plant growth. It is abundant in the atmosphere and in soil organic matter, but not in a form that plants can use. Conventional methods of providing nitrogen to plants include

(1) adding nitrogen fertilizers to the soil, or

(2) inoculating (coating) seed with nitrogen fixing bacteria. Nitrogen fixing bacteria convert atmospheric nitrogen to an inorganic form that is useable by plants.


In addition, the provide residual nitrogen, in the soil, which can reduce or eliminate nitrogen fertilizer requirements for the next growing season.
