A leguminous plant is a group of flowering plants that have vegetables or as foods grown from the ground knobs that enhance the ability of nitrogen-rich material.
Examples: acacia, peas, clover, beans and gorse.
The leguminous plant increases the soil ripeness due to the Rhizobium bacteria in the root knobs of the plants. These microscopic bacteria changes over atmospheric nitrogen to a shape which can be utilized by plants. This reduces the nitrogen deficiency in the soil and makes it abundant.
