WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebSoil pH is easily modified in most soils using sulfur or lime. However, before attempting to modify the soil, collect a soil sample to determine the existing soil pH and buffer pH. These soil properties are essential components to making informed decisions about amending soil pH.
