*A [[Bioretention|bioretention]] system in China used biochar layered with or mixed into lateritic red soil, with some success in contaminant removal. The mixed biochar–soil design achieved the highest water retention, and both biochar-amended systems removed more contaminants (TN, NH₃-N, NO₃⁻, TP, PO₄³⁻, and Cu) than systems without biochar (Premarantha et al., 2023) <ref>Premarathna, K.
