WebMost soils have pH values between 4 to 10. Most soils in Iowa have a pH between 5.5 to 7.5. More weathered soils generally have lower pH values, with soils in arid regions having higher pH values due to accumulations of calcium or sodium. Some soils have higher ‘buffering capacity’ or ability to resist change.
