What effect does nitrogen have on turfgrass growth?

• A. It stunts growth and promotes disease
• B. It promotes lush, green growth but can lead to increased pest susceptibility if overapplied
• C. It has no effect on turfgrass
• D. It decreases the water retention of the soil

Answer: (B)

Nitrogen is an essential nutrient for turfgrass and plays a critical role in promoting growth and vigor. When applied at the appropriate rates, nitrogen enhances chlorophyll production, which results in lush, green foliage and healthy growth. This nutrient is a key component in various plant processes, including photosynthesis and protein synthesis, both of which are vital for robust turf development. However, while nitrogen is beneficial for growth, its overapplication can lead to increased susceptibility to pests and diseases. Excessive nitrogen can cause rapid growth that stresses the plants and makes them more attractive to certain pests. This scenario can also lead to a reduction in natural resilience against diseases, as overly lush and concentrated growth can create an environment conducive to pathogen proliferation. Thus, the correct understanding of nitrogen's role in turfgrass management emphasizes the importance of balanced fertilization. Proper management ensures that the benefits of nitrogen can be enjoyed without the associated risks of increased pest problems.
