In order to determine the possible effects of metals in soil on plants and other living beings, it is being beneficial to determine the available and toxic concentrations of metals in the soil. For the improvement of soils with rich metal content, addition of organic remediators such as compost, or lime in the soil is among the applicable methods. In this study, it was aimed to examine the changes in the immediately available, potentially available and toxic concentrations of metals found in the soil having acidic character when municipal solid waste compost, lime (CaCO3) and commercial soil conditioners (A2 and T50) were used. When the toxicity characteristic leaching procedure results were examined, it was observed that the concentrations which can be regarded as the amount of compost added to the soil were increasing as toxic concentrations for heavy metals decrease. When the values are defined as immediately available which are expressing the weakly bound metal concentrations was determined that the mobility of metals in soil is pretty decreasing by the use of T50 from among the soil remediators. And by the use of lime, it was observed that the potentially available concentrations of metals are being reduced to minimum.
