This species has a symbiotic relationship with certain soil bacteria called Rhizobia. These bacteria form nodules on the roots of the plants and fix atmospheric nitrogen, plants may fail to flourish due to the absence of the appropriate Rhizobium species. Some of the nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
