The pH of natural soils typically ranges from 4.5 to 8.0. Soils with pH between 6.5 and 7.0 are considered to neutral, soils with pH above 7.5 are alkaline and soils with pH lower than 6.5 are acidic. WebSoil pH is a measure of acidity or alkalinity. A pH of 7 is neutral, above 7 is alkaline and below 7 is acid. Because pH is measured on a logarithmic scale, a pH of 6 is 10 times more acid than a pH of 7.
