Which fertilization practice is improper when establishing new turf stands?

• A. Fertilize new stands with nitrogen but not potassium.
• B. Fertilize new stands with potassium but not nitrogen.
• C. Do not fertilize new stands at all.
• D. Apply all three nutrients N, P, and K equally to new stands.

Answer: (A)

When establishing new turf, you want to support both shoot growth and a strong root system. Nitrogen pushes leafy growth and quick green-up, but potassium is essential for root development, water regulation, and overall stress tolerance. Fertilizing with nitrogen but not potassium creates an imbalance: the canopy may come in lush and green, yet the roots lag behind, leaving the stand vulnerable to drought, disease, and poor establishment. That’s why providing nitrogen without potassium is considered improper during establishment. A balanced starter approach—often with N and K (and some P if soil tests indicate a need)—helps new turf develop both a vigorous shoot system and a robust root system, leading to a quicker, healthier stand.
