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.
You can tell what percentage of nutrients is in your fertilizer by looking at the NPK number on the label of your chosen fertilizer. Nitrogen promotes growth and color. Phosphorous helps grass establish strong root systems and fight fungal diseases. Potassium aids in photosynthesis.
