What Is Soil pH?
Soil pH is a measure of how acidic or alkaline a soil is.
How to Understand It
On the pH scale, values below 7 are acidic, 7 is neutral, and values above 7 are alkaline. Soil pH influences nutrient availability. A soil test and grass-specific local guidance should inform amendment decisions; pH does not measure total nutrient supply.
