Which nutrient is commonly known to maintain lawn color and growth?

• A. Phosphorus
• B. Potassium
• C. Nitrogen
• D. Sulfur

Answer: (C)

Nitrogen fuels lawn color and growth because it is a major component of chlorophyll, the green pigment, and of the proteins that build leaf tissue. When nitrogen is available, grasses produce lush, green blades and rapid growth, which is why it’s the nutrient most closely linked to a vibrant lawn. A deficiency shows up as pale yellowing and weak growth, while too much nitrogen can cause overly soft, vigorous growth that invites disease and thatch. Phosphorus supports root development and establishment, potassium strengthens overall vigor and stress tolerance, and sulfur contributes to essential amino acids, but none have as direct an effect on color and leafy growth as nitrogen.
