In the PCA, five principal components (PC) describing more than 70 % of total variation were selected. The properties of the O and B horzons (pH,C,N, and S content, potentially dangerous Al forms) were in most cases separated, suggesting different processes and effects in each horizon. Spatial variation of PC scores was analysed using variogram,s maps of their distribution were creatd using kriging. Spatial correlation with stand factors"@cs . . "Pen\u00ED\u017Eek, V\u00EDt" .
