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.
Grass, like all plants, requires specific types of nutrients in order to thrive. These nutrients are broken down into macronutrients and micronutrients. Most fertilizers supply the macronutrients: nitrogen, phosphorous and potassium. Nitrogen supports green growth, while phosphorous plays an important role in plant photosynthesis and energy transfer.
