Exploring the potential of biochar for the remediation of microbial communities and element cycling in microplastic-contaminated soil

Scientists found that adding biochar (a charcoal-like material made from plant waste) to soil contaminated with microplastics helped restore healthy microbial communities and nutrient cycling. The biochar reversed negative effects that microplastics had on soil chemistry, including nitrogen and phosphorus availability. This suggests biochar could be a practical tool for repairing farmland damaged by microplastic pollution.
