Key Findings
- The study by the University of Zanjan found that applying 1000 mg/kg of nano silica increased soil pH by 6%, reducing the availability of heavy metals
- Nano silica reduced the concentrations of lead, zinc, copper, nickel, and chromium in the soil by 12%, 11%, 11.6%, 10%, and 9.5%, respectively
- Nano silica improved plant health by increasing phosphorus and potassium uptake by 25% and 26%, respectively, and enhancing soil enzyme activities
