N2 - Utilizing heavy-metal-contaminated agricultural land safely is an urgent problem. Comprehensive evaluation of remediation efforts and economic benefits of stabilizers on contaminated soil are the most important means to address this problem. Environmentally friendly stabilizers attapulgite (APT), attapulgite/carbon (APT/C), and phosphate mineralization bacteria products (PMBP) were analysed for their ability to stabilize Cd and Pb in soil under incubation conditions and to decrease the uptake of heavy metals by vegetables under greenhouse and field conditions. In incubation, pot, and field experiments, APT/C best stabilized Cd in soil, while PMBP had the best stabilization effect on Pb in soil. Based on effectiveness, cost, and improved yields, the optimal amounts of stabilizers were 5‰ APT/C and 0.21‰ PMBP. In practical applications, PMBP should be appropriately supplemented annually to ensure its efficiency. APT/C and PMBP can be used to treat heavy-metal-contaminated agricultural so
