Investigation of soil in Sumadija and Valjevo region shows that the highest content of total forms of Ni and Cr, and available Ni are in Leptosols of Maljen, and they are much smaller in zones of Rudnik and Cacak. Distribution with depth shows that origin of these elements is geochemical in soil on Rudnik and Maljen, while in Cacak anthropogenic influence are possible. Ni solubility (rate total/DTPA) is different, and it can not be realable factor for determination of pollution origin. Correlation between these forms is weak and moderate. According to level of pollution, suitable remediation measures are proposed.
