What role do mycorrhizal fungi play in plant health?

Mycorrhizal fungi play a vital role in plant health by forming symbiotic relationships with plant roots, which significantly enhance nutrient uptake. This relationship allows plants to access essential nutrients, especially phosphorus, which can be difficult for roots to absorb in some soils. The hyphae of mycorrhizal fungi extend far beyond the root zone, increasing the surface area for nutrient absorption and improving water retention in the soil, thus providing plants with a greater supply of nutrients and moisture.

The enhancement of nutrient uptake helps plants grow stronger and healthier, which is particularly important in nutrient-poor soils or when plants are under stress. This symbiotic relationship not only benefits the plants but also improves soil structure and health over time.
