    . The studied soil was sandy loam and soil columns with 20 cm length and 19 cm diameter were provided. Three levels of manures 0, 1 and 2 weight percentage and three levels of soluble Cd 0, 5 and 10 mg/lit were provided. Every 15 days, a pore volume of this soluble was added to the soil columns and output soluble was gathered and finally was measured by atomic adsorptionadsorptionSubject Category: Natural Processes

    . This step continued for 75 days. The soil columns were cut to sections of 3 cm diameter and the fixed Cd concentration was measured for each section. The amount of dissolved organic matter was measured for the soil columns. The results showed that more than 90% of added Cd remained in the soil. The highest concentration of Cd was observed in vermicompost treatments in depth of 0-3 cm and then 3-6 cm. The ability of poultry manure for Cd fixation was negligible and in most cases was less than control columns. In columns treated with poultry manure, the highest concentration of Cd was observed in the depth of 6-9 cm. The amount of dissolved organic matter in output solution from treatments of poultry manure was significantly more than other manures.
