Blue-green algae are an example of nitrogen-fixing bacterial that work independently. Independent nitrogen fixers transform less than 5 pounds of nitrogen per acre but are a significant source of nitrogen for rice paddies. In legumes, the nitrogen-fixing bacteria enter the root system of the plant. The infection causes the formation of a node for nitrogen storage. The plant supplies the food necessary to keep the bacteria alive in this symbiotic relationship. In alfalfa, the nodes form into hand-like structures with a palm and fingers approximately 1/2 inch in diameter.
