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.

"WebThe reactions with metal cations are pH dependent. At very low pH (<1.3), the main sorption mechanism is the reaction of phosphate ions with iron. Within the pH range of 1.3-4.3, the phosphate ions mainly create a complex with aluminium. At higher pH values (4.3-7.2), the phosphate ions are commonly in the form of hydrolysed phosphate ions.
