. Such bacteria are found - where grasses, cereals are grown. They fix atmospheric nitrogen and make it available to crops. Fixation of nitrogen by such bacteria may occur naturally in very ideal situation. But such fixation process may have to be enhanced by external application of bacterial cultu..
