From: Potential mechanisms involving the immobilization of Cd, As and Cr during swine manure composting
Changes in temperature (A), pH (B), electrical conductivity (C), and cation exchange capacity (D) during swine manure composting with different initial C/N ratios and bulking agent types. Different lowercase letters indicate significant differences among treatments, while the same lowercase letters indicate no significant differences among treatments (p < 0.05). The error bars represent the standard deviation of three replicates.
