DESCRIBE THE ROLE OF RHIZOBIUM IN MAINTAINING SOIL FERTILITY.

Dear student, 
​Please find below the solution to the asked query        

Plants cannot absorb nitrogen from the atmosphere. Rhizobium is a symbiotic bacteria present in the root nodules of leguminous plants. The bacteria helps the plant to fix the atmospheric nitrogen and convert it into useable form i.e ammonia. The ammonia, so formed, is oxidized first into nitrite and then to nitrates with the help of other soil bacteria by the process of nitrification. The nitrites and nitrates, thus formed enrich the soil with usable form of nitrogen that is easily assimilated by the plants.
Hence, by fixing nitrogen, Rhizobium helps in increasing the soil fertility.​

Rhizobium is a bacterium which converts atmospheric nitrogen to usable, nitrogenous compounds and fixes nitrogen in soil. Plants up take that nitrogen compounds to synthesis Proteins. Animals then eat plants and get proteins from it. Rhizobium is found in the nodules of leguminous plants such as gram, pea, pulses etc.
