Most of studies using urban solid waste compost showed that due to high organic matter content this organic fertilizer has an important role on physical and chemical properties of soil. Nano iron oxide powder also helps to adhere soil particles and makes better aggregate formation. In this research, the effects of different amounts of nano iron oxide powder and urban solid waste compost coated sulfur on infiltration rate, particle density and mean weight diameter of aggregates (MWD) of a saline-sodic soil in a randomized block design (factorial) was studied. Treatments were nano iron oxide powder at two levels (0 and 20 mg/kg) and urban solid waste compost coated sulfur at two levels (0 and 15 ton/ha) each with three replications. The effects of nano iron oxide and urban solid waste compost coated sulfur on physical properties of a surface soil (0-15 cm) were studied in plots of 4 m2 after harvest of sunflower plant. Results showed that application of urban solid waste compost coated sulfur led to a significant increase in infiltration rate, MWD and a significant decrease in bulk density of soil. Nano iron oxide treatments resulted in a significant increase in MWD and a slightly increase in soil infiltration rate, but did not show remarkable effect on soil bulk density. Interaction effect of urban solid waste compost coated sulfur and nano iron oxide showed that their application at a time resulted in higher infiltration rate, significant decrease in bulk density and significant increase in MWD in studied soil.
