Soil pH is a measure of the acidity or alkalinity (basicity) of a soil, and is reported as a value between 0 and 14. A soil test for pH measures the concentration of hydrogen ions in the soil solution.
A pH of 7.0 is considered neutral. A pH value below 7.0 indicates that the soil is acidic, with lower values representing increasing acidity. A pH value above 7.0 indicates that the soil is alkaline (basic), with higher values …
