Abstract: In the samples of Prokuplje Municipality agricultural soil, it was assessed the contribution of the organic matter and clay content influence on the corrected remediation values of the total forms of Cd, Cr, Pb and Ni maximum allowed concentrations (MAC). A total of 25 samples were analyzed, of which 8 samples were on Fluvisol type of soil, 3 samples were on Vertisol type of soil, 12 samples were on Eutric cambisol type of soil, and 2 samples were on Humofluvisol type of soil. In composite soil samples, taken from a depth of 0-30 cm, certain parameters of soil fertility (content of clay fraction and total forms of Cd, Cr, Pb and Ni), were determined.The interpretation of the obtained results was carried out in relation to the MAC of tested microelements defined in the Regulation on permitted levels of hazardous and harmful substances in the soil, and based on the formula for calculating threshold and remediation values according to Ordinance on the program of soil quality systematic monitoring, indicators for risk assessment from soil degradation, and methodology for developing remediation programs. A high correlative dependence related to the content of organic matter was determined for Vertisols and Humofluvisols, while it was low for Eutric cambisol and Fluvisol. The correlative dependence related to the content of clay fraction showed a strong correlation, for all examined soils.
