Biochar and drilosphere soil synergistically form a low-cadmium, high-nutrient remediation hotspot: Insights from microbial functional gene and enzymatic stoichiometry analyses.
The drilosphere is a biogeochemical hotspot, but its role in biochar-assisted remediation of cadmium (Cd)-contaminated soil remains unclear. Comparisons were made between fresh (RS) and aged rice straw (ARS) biochar treatments at different Cd contamination levels to assess their effects on the drilosphere microenvironm...
