Which factor is crucial for the prevention of turf diseases?

Maintaining the correct soil pH is essential for preventing turf diseases because soil pH directly affects the availability of nutrients to the grass and the overall health of the soil ecosystem. If the soil pH is too high or too low, it can lead to nutrient deficiencies or toxicities, which may weaken the grass. Healthy, well-nourished grass is more resilient against pathogens that cause diseases.

Furthermore, a suitable pH level promotes the development of beneficial soil microbes, which can suppress harmful pathogens and contribute to a healthier turf environment. Therefore, effective management of soil pH is fundamental to ensuring that the turfgrass thrives and is less susceptible to diseases.
