What is the ideal pH range for most turfgrasses?

The ideal pH range for most turfgrasses typically falls between 6.0 and 6.5. This range is optimal because it allows for better nutrient availability and uptake by the grass roots. Turfgrasses thrive in this slightly acidic environment, which enhances microbial activity in the soil, promoting healthy growth and resilience. Within this pH range, essential nutrients such as nitrogen, phosphorus, and potassium become more soluble and accessible to the plant, supporting robust growth and overall health.

When soil pH is below this range, at more acidic levels, it can lead to the solubility of certain toxic metals and reduced availability of key nutrients, adversely affecting turf health. Conversely, soil pH that rises above this range can lead to nutrient deficiencies, particularly for essential micronutrients. Thus, maintaining a soil pH within the 6.0 to 6.5 range is crucial for optimal turfgrass management and health.
