On average, the most desirable results for the soil pH and the chemical composition were obtained with MQW applications. The application rate of MQW equal to the agricultural lime requirement of an acidic soil may be sufficient for reclamation. Therefore, as reported in the previous works (Tozsin et al., 2014a,b), the results of this study show that marble wastes (especially the MQW) could potentially and alternatively be used as an acid-neutralizing material and a regulating agent for the mineral composition of an acidic soil
