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.
A plant needs nutrients to survive. Most of these are provided by the soil, but soil varies tremendously in nutrient amounts, soil type, pH, and nutrient availability. The three main nutrients that have been identified as absolutely necessary for plants are nitrogen (N), phosphorus (P) and potassium (K). These three are also known as macronutrients, and are the source of the three numbers commonly found on organic fertilizer labels. The numbers found on our All-Purpose Fertilizer, for example, are 5-5-5. This is the percentage by weight of the N, P, and K found in the fertilizer. So whatâs so important about nitrogen, phosphorus and potassium?
