What is a good turf management goal to promote adequate nutrient uptake?

• A. Increase mowing height
• B. Apply lime to adjust soil pH
• C. Focus on practices that promote a healthy root system
• D. Use pesticides for disease control

Answer: (C)

Nutrient uptake in turf is driven by the health and extent of the root system. When roots are strong and widespread, they explore more soil, access water effectively, and absorb nutrients more efficiently, making root health the best foundation for adequate uptake. So, focusing on practices that promote a vigorous root system directly supports how nutrients move from soil into the plant. This includes maintaining good soil structure to prevent compaction, managing irrigation to avoid drought stress or waterlogging, and applying fertility in a way that encourages root growth rather than only leaf production. Increasing mowing height can improve overall vigor and may support deeper roots, but it isn’t the most direct goal for nutrient uptake. Lime adjusts soil pH to improve nutrient availability, which helps uptake, yet without a strong root system, the benefits are limited. Pesticides protect against disease, which helps plant health, but they don’t directly enhance the plant’s ability to take up nutrients.
