Fertilizers supply essential nutrients to the turfgrass for proper growth and development.
Nitrogen (N) is one of the most applied macronutrients because turfgrasses require it in the highest amount.
Phosphorus is an essential nutrient for turfgrass growth and development.
Potassium is an essential nutrient for turfgrass growth and development.

Sulfur (S) is a secondary macronutrient relative to the primary macronutrient of nitrogen, phosphorus and potassium, but is still essential for plant growth.
Iron (Fe) is a micronutrient, meaning it is required in lower concentrations by the turfgrass relative to macronutrients, but is essential for turfgrass growth.
Micronutrients are needed in lower quantities by the plant compared to macronutrients.
Soil testing is one of the most basic components for developing a sound turfgrass fertility program.
