The field experiment with fertilizer treatments of spring wheat on four different levels of soil supply with mobile phosphates has been conducted in 2005-2007 on sod-podzolic loam sandy soli contaminated with radionuclides. It was found a damped function decrease of 137Cs and 90Sr transfer to wheat grain up to 1.5 - 1.6 times according to change of mobile P2O5 content in soil from 70 to 393 mg/kg. Increasing the soil phosphate content up to 400 mg/kg with simultaneous application of fertilizers N60+30P60K180 could result in double reduction of 90Sr accumulation in wheat grain
