WebKey Points. Soil pH is a measure of the concentration of hydrogen ions in the soil solution. Low pH values (< 5.5) indicate acidic soils and high pH values (> 8.0) indicate alkaline soils. Soil pH between 5.5 and 8 is not usually a constraint to crop or pasture production. In South Australia more than 60 % of agricultural soils are alkaline.
