"WebJul 26, 2024 · Importance of pH Testing. Soil pH is as crucial as location, exposure, and soil preparation. pH is a measurement of the degree of acidity (sourness) or alkalinity (sweetness) of soil, on a scale of 0 to 14, with lower numbers being more acidic and higher numbers being more alkaline. The value of 7.0 is neutral—i.e., neither acidic nor alkaline. " - Sph for soil
