Short summary
Cadmium (Cd) contamination in soil has severely threatened human health. In this study, we investigated the possibility of applying oyster shell and biochar to reduce Cd uptake by crops and improve soil fertility and enzyme activities in field experiments under rice–oilseed rape rotation, which provided an economical and effective pathway to achieving an in situ remediation of the Cd-contaminated farmland.
