Azospirillum is a genus of bacteria that plays a crucial role in promoting plant growth. These bacteria are known for their ability to fix atmospheric nitrogen, converting it into a form that plants can use. They often form beneficial associations with the roots of various crops, enhancing nutrient uptake and improving soil health. These bacteria are commonly found in the rhizosphere, the region of soil surrounding plant roots. By producing growth-promoting substances, Azospirillum helps plants develop stronger root systems and increases their resistance to stress. This makes them valuable for sustainable agriculture and improving crop yields.
