: Structure, genesis and resources efficiency of dolomite: New
2021.7.5 Dolomite as an economical calcareous material can be used as a soil amendment to remediate acidic soil ( Shaaban et al., 2017 ). Dolomite can react with H + in the soil to release CO 2, and, thereby, improve acidic soil and increase the pH ( Shaaban et al., 2014 ), but the process is slow.
