A field experiment was conducted in summer season 2007 at the farm of Rice Research and Training Center farm Kafr El-Sheikh to study the impact of FYM and urea and their combination with using drainage water for irrigation on availability of some heavy metals such as Lead(Pb), nickel (Ni), Cadmium (Cd). Results indicated that the highest values of available pb⁺², Ni⁺², Cd⁺² were found with the combination of 150 kg urea plus the rate of 9 ton FYM.Fed^-1. Data indicated that ,the lowest values of available Cd²⁺,Ni²⁺ and pb²⁺in soil were found at flowering stage compared with the other stages at all treatments. The results of simple correlation coefficient ( r )between organic matter ( OM) ( y ) and each of available Pb⁺² (X₁), available Ni⁺² ( X₂) and available Cd⁺² (X₃ ) at harvest stages  showed the character most closely associated with organic matter was the available Pb⁺² (X₁ ) (R= 0.9) . Multiple linear regressions showed that the prediction equation for organic matter was formulated as follows: Y = -0.8+ 0.224 X₁ + 0.301X₂ + 2.62 X₃
