After the failure of lime potential equation – a simulation model of soil acidification, only the empirical way was available for carrying out dependence between soil pH and the exchangeable ions. In authors previous works on the correlation pH – exchangeable cations in 15 profiles of Chernozems and 6 profiles of Grey forest soils were found high and proved correlation coefficients. In this work are reported the results for 10 profiles of Luvisols WRBSR, 2006 - Luvisols and Podzol Luvisols. An equation y = a + b lnx describes the dependence pH – ex. Al with a correlation coefficient r = 0.72 and another equation y = a + blnx describes the dependence pH – ex. Mn with a correlation coefficient r = 0.61.
