Abstarct: Today, overuse of chemical fertilizers to increase agriculture products have caused ecological imbalance of the environment and negative effects on human health which is serious risk. The use of municipal solid waste compost addition to providing the required elements in soils and plants can help to reduce the negative effects of chemical fertilizers. To study the effect of different amounts of municipal solid waste compost on some soil properties and the amounts of Fe, Cu, Mn and Zn in plant, an experiment was conducted at Shahed university of Tehran in which four fertilizer treatments (including 0, 15, 30 and 60 Ton ha-1 compost) were compared with three replications. Twelve weeks after corn planting, the concentrations of these elements were measured in plant and soil. The results showed that the use of municipal solid waste compost increased concentrations of Fe, Mn and Zn in the plant compared to control treatment. This increase was statistically significant at 1% level. Also the use of municipal solid waste compost increased Cu concentrations in shoots compared to control. This increase was also statistically significant at 1% level. However, Cu concentration in leaves was not significantly different compared to control. The results also showed that compost significantly increased the availability of Fe, Cu, Mn and Zn in soil at the level of 1%. Compost application increased soil organic carbon content but reduced its pH. Increase in organic carbon and decreasing pH was statistically significant at 5% level. According to the results, the use of municipal solid waste compost increased concentrations of Fe, Cu, Mn and Zn in soil and plant. Since some micronutrients deficiency in the areas with high pH and calcareous soils like Iran is the most common, application of municipal solid waste compost could be useful in these areas
