There are 1700,000 hectare rangeland in Ilam province that they can produce about 236000 ton hay and there are not any information about quality and quantity of the minerals. This research carried out for 3 years in order to study minerals status of range plant of Ilam province. Samples were taken from 31 areas along grazing season for 4 time. In each area 3 range were chosen randomly and samples after drying in room were mixed, consequently 124 samples analyzed for minerals. The results showed that average of ash, Ca, P, Mg and K in dry matter basis for first, second, third and forth cuts were 13.26, 1.15, 0.27, 0.31, 1.47 and 10.80, 1.09, 0.26, 0.30, 0.45 and 8.51, 0.99, 0.25, 0.29, 1.41 and 8.39, 0.91, 0.24, 0.27, 1.35 percent and average Fe, Mn, Cu, and Zn for first, second, third and forth cuts were 281.95, 45.61, 9.47, 29.67 and 289.25, 45.16, 9.24, 28.54 and 275.69, 44.27, 9.09, 27.88 and 262.44, 43.42, 9.12, 28.15 mg/kg respectively. The stages of sampling had significant effects (p0.01) on ash, Ca, P, Mg, K, and Fe and that have not significant effect (p0.01) on Mn, Cu and Zn. There were significant differences (p0.01) between 3 years for all minerals exception Mn an Zn. Average of Ca, Mg and Cu were higher than the requirments of ruminants.
