The objective of this study was to determine the effect of different concentrations of municipal waste compost (0, 40, 80, 120 and 160 t ha(-1)) on soil physical properties of vertisol and non-calcareous brown soils. According to the results, the waste compost application to the soil increased its porosity and reduced the bulk density. In general, adding waste composts to soils positively affected the soil physical properties of non-calcareous brown soils. However, addition of waste compost to vertisol soils with high clay contents did not significantly change the soil aggregate stability. The best compost application levels among applied doses were 120 and 160 t ha(-1).
