The Luvisols of South Bulgaria have been developed during a long period in tropical climate under oak forests. This is the reason why soil-formation process in them is advanced and some had need of liming. This article shows the final stage of a research on the possibility to calculate the Lime Rate by soil pH values. A large number of literary data are checked in the statistical program TableCurve. An equation y-1 = a + bex describes the dependence pH – ex. Al with a correlation coefficient r2 = 0.923.
