•Marble wastes at different rates were applied to an acidic soil.•The effects of marble wastes on altering chemical composition of soil were evaluated at the end of 75 incubation period.•The MQW and MCW applications significantly increased soil pH, CaCO3 content, exchangeable Ca and Na contents.•The MQW and MCW applications decreased exchangeable K, plant-available P and extractable Fe, Cu, Mn and Zn contents.•Heavy metal (Cd, Ni and Pb) concentrations also decreased with marble waste applications. Soil acidity greatly affects the availability of plant nutrients. The level of soil acidity can be adjusted by treating the soil with certain additives. The objective of this study was to determine the effect of marble quarry waste (MQW) and marble cutting waste (MCW) on the chemical composition and the acidity of a soil. Marble wastes at different rates were applied to an acid soil. Their effectiveness in neutralizing the soil pH was compared with that of agricultural lime. The changes in the chemical composition of the soil were also evaluated with column test at the end of a 75-day incubation period. The results indicated that the MQW and MCW applications significantly increased the soil pH (from 4.71 up to 6.54), the CaCO3 content (from 0.33% up to 0.75%), and the exchangeable Ca (from 14.79cmolkg−1 up to 21.18cmolkg−1) and Na (from 0.57cmolkg−1 up to 1.07cmolkg−1) contents, but decreased the exchangeable K (from 0.46cmolkg−1 down to 0.28cmolkg−1), the plant-available P (from 25.56mgL−1 down to 16.62mgL−1), and the extractable Fe (from 259.43mgL−1 down to 55.4mgL−1), Cu (from 1.97mgL−1 down to 1.42mgL−1), Mn (from 17.89mgL−1 down to 4.61mgL−1) and Zn (from 7.88mgL−1 down to 1.56mgL−1) contents. In addition, the Cd (from 0.060mgL−1 down to 0.046mgL−1), Ni (from 0.337mgL−1 down to 0.092mgL−1) and Pb (from 28.00mgL−1 down to 20.08mgL−1) concentrations decreased upon the treatment of the soil with marble wastes.
