Abstract: The aim of this study was to estimate the long-term effect of orcharding utilization on the total content of Cu, Zn, Mn, Fe and their available forms in soils. For the investigation three apples tree orchards planted on the Cambisols from the Brda Valley Region were selected. The content of Cu and Zn in the humus horizon was much higher than in parent material due to the anthropogenic pollution. In the analyzed soils it was observed that, total Cu and Zn content and DTPA-extractable Cu, Zn, Mn, Fe was statistically positively correlated with the content of organic carbon. The content of DTPA-extractable Cu to the total content of Cu was high and reached up to 24,6% at the humus horizon. It was stated, that available forms of copper, manganese and iron was statistically positively correlated with the acid reaction. The total content of Cu, Zn, Mn and Fe did not exceed acceptable concentrations for uncontaminated soils.
