The basic soil test for turfgrass includes nitrogen, phosphorus, and potassium.

• A. True
• B. False
• C. Not sure
• D. Only nitrogen

Answer: (A)

A basic turfgrass soil test checks the three primary nutrients: nitrogen, phosphorus, and potassium. These macronutrients are needed in larger amounts by turf, supporting leaf growth (nitrogen), root development (phosphorus), and overall health, stress tolerance, and disease resistance (potassium). Measuring their available forms lets you tailor fertilizer plans to avoid both deficiencies and waste, giving you a solid foundation for healthy turf. So the statement is true because standard testing evaluates N, P, and K to guide amendments. Choosing only nitrogen would miss essential nutrients, and affirming “not sure” or “false” wouldn’t align with typical turf management practice.
