The relation between soluble trace element content and pH Correlation calculation has been made also for the connection between soluble element content and pH. The calculations have been made for Mn, Zn, Cu, Pb and the pH separately for elements and sections. For these calculations all out data had to be standardized. The standardized data are ' shown in Table 5, the values of r are shown in Table 2, The connection of the soluble trace element content and the pH shows that pH has a relatively high correlation to all the elements. An exception is Zn, which in most cases does not show correlation with pH.
