Azospirillum, Fixing Nitrogen Like a Boss
Flatulance, while this might be an oversimplification, is essentially the process from which Azospirillum convert nitrogen gas to plant usable, ammonia (NH3). When it comes to nutrition nitrogen is the limiting factor in plant growth, playing a key role in almost every process of a plants life. In effect, azospirillum also affect almost every process of a plant’s life. So yeah, it’s pretty important!
Nitrogen exists in our air and our soil. Actually, 78% of our atmosphere is made of nitrogen (N2). The way it exists in our atmosphere doesn’t do much for our plants unless it can take on a solid form. Nitrogen-fixing bacteria take in nitrogen the way that we do oxygen.
Then they excrete it as a solid form that plants can use. When nitrogen is taken from gas to solid, it is called nitrogen fixation.
