In a field study , with rice plants, of flooded rice soils whose organic matter content was 1.5 % ,incorporation of composted rice straw either alone or in combination with nitrogen fertilizer affected the availability of some nutrients NH4-N, P, K ,Fe2+,Mn2+and Zn2+ in addition to N03-N concentration. The obtained data showed that the integration of composted rice straw plus nitrogen fertilizer increased the availability of NH4-N, P, K ,Fe2+ and Mn2+ but decreased Zn2+ availability and N03-N concentration. Data of simple correlation coefficient (r) between the phosphorus availability and zinc availability was positively. The linear regression coefficient showed that the prediction equation for zinc availability (y) could be formuled as follows:
Available Zn = - 0.477 + 0.0540 Available P.
