Evaluate the safety and efficacy of vermicomposted fly ash as an agricultural soil amendment to improve soil fertility, microbial activity, and crop performance.
Assessed trace element toxicity using the coefficient of pollution and potential ecological risk index.
Amended agricultural soil with varying concentrations of vermicomposted fly ash and monitored physicochemical properties, microbial biomass carbon, and enzymatic activities for 90 days.
Measured germination rates, growth, and yield in tomato (Lycopersicon esculentum) and brinjal (Solanum melongena) crops.
Trace element toxicity analyses indicated no apparent ecological risks associated with vermicomposted fly ash application.
Vermicomposted fly ash amendments significantly (p < 0.05) improved soil quality, raising nitrogen to 2.86% and phosphorous to 1.05% while enhancing microbial biomass and enzymatic activity up to 90 days.
Crop seed germination significantly (p < 0.05) reached 82.22% with enhanced plant growth in both tomato and brinjal.
