Trichoderma harzianum-loaded maize biochar enhances Cd-Cu immobilization and reduces bio-accessibility in contaminated soil.

The use of microbial loaded biochar in soil remediation is becoming popular worldwide. In the current research, a maize straw biochar (MB) and Trichoderma harzianum loaded biochar (MBT) were used at various rates in Cd-Cu dual polluted soil, to see their effect on Cd-Cu removal and to explore vigorous changes of metals bio-accessibility. Throughout the 90 days of remediation experiment, the dynamic impacts on the soil's physiochemical characteristics were noted.
