The accuracy of the Shoemaker-McLean-Pratt single buffer method and its double buffer variation was compared for determining the lime requirement of 41 acid mineral soils in Ontario. The single buffer method gave good prediction of the lime requirement when calibrated against Ca(OH) 2 -titrated soil acidity using a quadratic equation. Key words: Lime requirement, acid soils, SMP buffer
