Answer
A special category of soil bacteria (Rhizobium) is found living in small nodules on the roots of leguminous plants. These bacteria pick up free nitrogen from the soil and atmosphere and convert it into soluble nitrates. These nitrates are used by the host plant and also by other plants sown later in the same soil.
