The cooperative application of oyster shell and biochar efficiently enhanced in-situ remediation of cadmium contaminated soil around intensive industry
Abstract:Abstract. Biochar has been widely used for the in-situ remediation in the cadmium (Cd) contaminated soil, while the high-cost of biochar limited its application in farmland. In this study, we firstly investigated the possibility of cooperative application of oyster shell and biochar to enhance Cd immobilization efficiency and reduce the cost in field experiments under rice-oilseed rape rotation. Treatments were comprised of: rice planting without amendments (R-PA0); followed with 15000 kg/ha biochar (R-PA1); f… Show more
