摘要:
Cadmium (Cd)-contaminated rice paddies have been a primary environmental concern worldwide. Biochar or modified biochar application favors reducing Cd availability in paddy soil, which has been demonstrated in physical and chemical terms. However, we know little about soil microbial responses after biochar application. In this study, we revealed the immobilization effect and mechanism of Cd in paddy fields by a novel phosphorite magnetic biochar (PMCB) from the perspective of soil microbial response. The results suggested that PMCB application ...
