The amount o f pure CaC03 required to raise the pH(HzO) o f 158 acid top and subsoils o f the Highveld Region to 6,5 was determined. The abovementioned quantity o f CaC03 is referred to as incubation lime requirement. The soils represent the Hutton, Avalon and Clovelly forms. pH(H20) values range from 4,5 to 6,4 with an average o f 5,6.
