In this study, the effects of gyttja on some soil properties in two different nickel-contaminated soils (Inceptisol and Entisol) were investigated. This study was conducted with the application of three levels of gyttja (0, 5 and 10%) in two different soils (Inceptisol and Entisol) contaminated with Ni at three levels of concentration (0, 40 and 80 mg kg(-1)) in a factorial experimental design with three replications. Some soil properties showed differences in different nickel and gyttja applications. Soil nickel content significantly (P < 0.01) increased in nickel-contaminated soils. Soil organic matter and phosphorus contents in gyttja applicated soils were found to reach higher levels compared to those without gyttja application.
