Settler and different organizations produce a large amount of trashes in numerous forms, frequently making our environments dirty and unpleasant. The municipal discarded solid and fluid waste disposal deteriorating soil quality through a decrease in quality indicators because of the indiscriminate dumping of varies waste. Therefore, the focus of this study was to determine urban waste disposal effects on soil quality at open waste dumping sites of Asella city, Arsi zone, southeast Ethiopia. The analysis revealed that all soil samples at the various horizons in all sites were insignificant in BD at surface and subsurface of onsite (2.72, 3.17g/cm3) and offsite (2.99, 3.29g/cm3) and SMC at the offsite (13.03, 12.44%). At the study area, there was an elevation of soil pH at the disposal site and offsite from 4.19 to 5.28 and from 4.43 to 4.12 with subsurface to surface respectively. Moreover, BD, Cd and Ni excess in both onsite (2.96g/cm3, 5.4mg/l and 47.20mg/l ) and offsite (3.13g/cm3, 3.6mg/l and 35.03mg/l ) and at the surface onsite and offsite ((2.72, 2.99g/cm3), (7.96, 4.78mg/l), (52.43, 39.05mg/l)) and subsurface onsite and offsite ((3.17, 3.29mg/l), (2.85, 2.38mg/l), (41.97, 31.00mg/l)) respectively. In both onsite and offsite, the higher values of moisture content have resulted at the surface and the lower was at the subsurface of soil 14.93, 13.03% and 12.40, 12.44% respectively. It was concluded that the urban waste disposal has a toxicity effect on the soil and therefore, the management was required to undermine the cause of waste and treating the wasted within incineration, phytoremediation and bioremediation system.
