In return, the bacteria provides the plant with nitrogen in forms that the plant can take in. Nitrogen fixing bacteria change nitrogen from the air into nitrogen compounds such as ammonia, nitrate, and nitrogen dioxide. They do so, through two living arrangements. One's as free living bacteria in the soil. The other's in association with plants of the Fabaceae and Leguminosae families, such as beans and peas.
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so th â¦ at plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle.
