Soil pH, biomass and Cd content of peanutSoil pHFigure 1 shows that, in this study, application of slaked lime significantly increased soil pH in nearly all growth stages (p  C1200  > C900  > C600  > C300  > C0. Among the soil characteristics, soil pH is considered as an important index that impact Cd uptake by crops, since pH can obviously affect the speciation and solubility of Cd in soil liquids15. The use of slaked lime can neutralize excessive H+ concentrations in soil solutions and decrease Cd solubility33, but there were no observable differences among the different growth stages.Figure 1Effects of slaked lime application on soil pH values. The values are means (± SD) of three replicates. Bar groups with different capital letters indicate significant differences (p  More
