What role do mycorrhizal fungi play in turfgrass?

Mycorrhizal fungi form a symbiotic relationship with the roots of turfgrass and other plant species, fundamentally enhancing nutrient uptake. These beneficial fungi extend the root system through their hyphal network, allowing the plant to absorb water and nutrients, particularly phosphorus and other essential micronutrients, more efficiently than the plant roots alone could achieve.

This symbiotic relationship not only improves nutrient availability but also promotes overall plant health, increases drought resistance, and enhances soil structure. The presence of mycorrhizal fungi can lead to improved turfgrass growth, vigor, and resilience, particularly in stressed environments.

In contrast, the other options suggest negative effects that mycorrhizal fungi have on nutrient uptake and root development, which is contrary to their established role in supporting plant health.
