In this research, three wastewater sludges which were different in origin were amended to soil samples taken from Bursa-Ozluce region at rates equivalent to 100t/ha and an incubation study was performed during a period of 12 months. Soil samples which have similar physical properties were taken from two agricultural lands: nonirrigated and irrigated from polluted Nilufer-Ayvali stream. Total and anorganic nitrogen forms and nitrogen mineralization ratios in sludge amended soils were compared and probable differences which might occur due to irrigation were studied.
