Effect of Municipal Waste Compost on Some Chemical Characteristics of Clay Soils

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 chemical properties of Vertisol and Non-calcareous Brown Soils. According to results of soil that sampled from pots, waste compost application to soil increased soil total nitrogen (TN), phosphorus (P2O5) and potassium (K2O) compared to control. 160 t ha-1 compost application levels resulted in the highest organic matter, TN and K2O among applied doses for both soil types
