WebSoil pH. Soil pH is a measure of the soil’s relative acidity or basicity. The pH scale ranges from 0 to 14. A pH of 7 is a neutral state, representing the value found in pure water. Values above 7.0 are basic, while values below 7.0 … WebAt high soil pH, most phosphorus is in the form of calcium compounds.
