Rhizobium

Rhizobium is a type of beneficial bacteria that forms a close relationship with certain legume plants, like beans and peas. These bacteria inhabit nodules—small growths on the plant's roots—and help convert atmospheric nitrogen into a form the plant can use for growth. This process, called nitrogen fixation, enriches the soil with essential nutrients, reducing the need for artificial fertilizers. Rhizobium's symbiotic relationship is vital for sustainable farming and maintaining healthy ecosystems, as it naturally enhances soil fertility and supports plant health.
