In durf-podzol light-loamy soil with increasing of PH and mobile phosphorus and potassium content levels the mobility of lead (Pb) and zinc (Zn) is reduced but the cadmium content is grown. However, the soil content of the mobile forms of copper, zinc, lead and cadmium in all the studied fertility backgrounds and high phosphate content soil didn't exceed maximum allowable concentration. The application of double superphosphate, polyphosphate of calcium, supercarolinphosphate, sulfoammophosphate in high doss (300 mg P2 O5 mg/kg of soil) haven't led to heavy metal's pollution of soil. Polyammophosphate and polyphosphate of calcium in comparison with phosphorus fertilizers containing phosphorus in orthoform furthered a little increasing of zinc and lead mobility in soil
