Short summary
Effective strategies are needed to remediate heavy metal pollution while supplying carbon (C) to maintain microbial activity and soil fertility. In this study, we revealed that optimised straw:biochar ratio (1 : 3) provides a novel integrated approach for remediating heavy metal-contaminated agricultural soils while simultaneously enhancing soil C stability, nutrient availability, and microbial activity.
Effective strategies are needed to remediate heavy metal pollution while supplying carbon (C) to...
