Lawn nutrients like potassium, phosphorus and, yes, nitrogen, support the process of photosynthesis. In short, nitrogen is what makes your grass green, and the greener the grass, the more photosynthesis can occur and the thicker the lawn gets. But be careful! Too much nitrogen can create big problems for your lawn.
Thus in fertile turfgrass soils this process is of limited importance whereas in unfertilized prairie soils the 10 to 25 pounds of N fixed per acre per year is ecologically relevant. Another benefit of soil microbes is their ability to degrade pest control chemicals and other hazardous materials reaching the soil.
