Which statement best describes the recommended approach to nutrient uptake in turf systems?

• A. Focus on practices that promote a healthy root system
• B. Focus on surface leaf feeding only
• C. Increase pesticide use
• D. Remove turf regularly

Answer: (A)

Nutrient uptake in turf systems is driven by a healthy, active root system. The roots are the primary pathway for nutrients to move from the soil into the plant, and their extent and vigor determine how effectively nutrients are accessed, especially as some nutrients are deeper in the soil or tied up in soil chemistry. When the roots are strong and well-developed, they explore more soil volume, take up water efficiently, and support beneficial relationships with soil life that help release and transfer nutrients to the plant.

To support that root health, management should focus on practices that keep the root zone in good shape: avoiding soil compaction so roots can grow and oxygen can reach them, maintaining proper irrigation to prevent both drought stress and waterlogging, improving soil structure with organic matter to enhance aeration and drainage, and conducting soil tests to tailor fertility and keep pH in a range where nutrients are available. Fertilizers should match the turf’s growth needs and be applied in a way that supports steady root uptake, not just quick top growth.

Leaf-only feeding treats the above-ground tissue and doesn’t address the root’s ability to absorb nutrients, so it’s not the best approach for overall uptake. Increasing pesticide use can disrupt beneficial soil organisms and stress the plant, which also isn’t helpful for nutrient uptake. Regularly removing turf reduces the root system and soil biology, further hindering nutrient absorption. Prioritizing practices that promote a healthy root system provides the most reliable foundation for effective nutrient uptake.
