"Weblaboratories in the Western Cape use the KCl method. When the soil solution has a pH(KCl) below 5,5 (pH (H20) < 6,5), it means that the amount of active hydrogen ions (H+) is too high, which causes soil to be overly acid and to have a negative effect on root growth. Lime should therefore be applied to make a correction. Using information " - Soil ph using kcl and water
