In this study, three types of chelated iron containing fertilizers (Sulufeed, Frilan iron cheated with EDDHA, Petrokimia - chelated Fe-EDTA and iron sulfate were compared . This research was conducted in 2013 in two phases. First stage an incubation experiment availability of iron in soil in at two time periods were studied. So in a greenhouse experiment the effect of fertilizer in tree levels (15,30,45 ppm) on plant growth parameters were also investigated. The results of incubation experiment, Frilan fertilizer and sulufied had more soil iron content (6.1 &9.3 mg/kg) at 38 days’ period and at 56 days all treatment, showed a relatively similar levels of iron content. The results of corn growth experiment under fertilizer treatments indicated that highest leaf Fe content (80 mg/kg) and soil Fe content(8mg/kg) after harvest were for the sulufeed  treatment. In general, sulufeed and Frilan had better performance in all experiment with respect to iron uptake on release of iron.
