A slow-release silicon amendment made from electrolytic manganese residue and phosphogypsum converts SiO2 to soluble silicates and releases silicon for up to 170 days.
- Why it matters: Large stockpiles of EMR and PG threaten soil sustainability by promoting nutrient loss and heavy-metal contamination, motivating safer, longer-lasting remediation.
- What they did: Using mechanochemical-thermal activation with biomass and sodium carbonate, the study produced S/CRF with lipid barriers and dissolution channels to control Si release, then tested it in lead- and cadmium-contaminated soils.
- The result: With 5% S/CRF-1, weakly acidic Cd and Pb decreased by 2–10% and 13–18%, residual forms increased by 7% and 6%, soil pH and nutrients improved, microbial communities were enriched, and TCLP leaching met safety standards.
