Abstract: This study examines the potential of earthworms (Lumbricus terrestris) in reducing pesticide contamination in soil. A controlled experiment was conducted using Puradan (0.5%), Ammonium Sulfate 21-0-0 (0.5% and 0.25%), and 14-14-14 Complete Fertilizer (0.5% and 0.25%), with each treatment containing 55 earthworms. One-way ANOVA and t-tests were applied to analyze pesticide contamination levels and earthworm survival rates. Results showed that higher chemical concentrations significantly reduced earthworm populations, with complete mortality observed at 0.5% contamination levels. Findings suggest that Lumbricus terrestris can absorb contaminants but are highly sensitive to chemical toxicity. The 0.5% Ammonium Sulfate group saw a reduction from 55 to 19 earthworms in one week, while the 0.25% group experienced fewer deaths. Excessive chemical use threatens soil health and agricultural productivity. Future research should explore long term effects in diverse soil conditions and strategies to enhance earthworm resilience in contaminated environments.
