Leguminous plants, which include peas, beans, clover, gorse, acacia, and carob, are a group of flowering plants with pods (or vegetables) as foods grown from the ground knobs, enabling the capacity of nitrogen-rich material.
The presence of Rhizobium bacteria in the root knobs of leguminous plants increases soil ripeness.
These minuscule bacteria convert nitrogen from the environment into a form that plants can use.
This reduces nitrogen deficit in the soil and increases its productivity.
