1)Rhozobia living in root nodules supply nitrates , nitrites amd amino acods to the plant and in exchange get energy on the form of carbohydrates from it . Such a mutually beneficial relationship is called symbiosis.
2)Rhizobia produce nitrogenous compounds from atmospheric nitrogen. However for the process of nitrogen fixation, they need leguminous plants like beans , sweet pea, soyabean, etc. as 'host'. Beans and pulses are rich in proteins due to the nitrogenous compounds made available by rhizobia.
3)The use of rhizobium has helped to reduce the use of chemical fertilizers and therby their adverse effects.
4) Nowadays, seeds are coated with Rhozobial solution or powder before sowing. After sowing rhizobia enters the plantlets. This is called as 'rhizobial inoculation'.
