Increases in Ca/Mg ratios caused the increases in the mobile fractions of Cr and Ni in serpentinite-derived soils in humid Asia

Serpentinite-derived soils are characterized by low Ca/Mg ratio and abnormally high Cr and Ni concentrations due to the geogenic sources. The breakdown of parent materials during pedogenesis may lead to the changes in both Ca/Mg ratios and fractions of Cr and Ni. This study hypothesized that total C...
