ClearEffect of biochar on soil microbial community, dissipation and uptake of chlorpyrifos and atrazine
Researchers tested biochar — a charcoal-like material made from mint-distilling waste — as a soil amendment to reduce contamination from two common pesticides, chlorpyrifos and atrazine, finding it significantly sped up pesticide breakdown and reduced uptake into plant tissues. The biochar also boosted populations of beneficial soil bacteria that help degrade these chemicals, suggesting it could be a practical tool for cleaning up pesticide-contaminated farmland.
