Iron-Enriched Carbonized Straw Reduces Rice Antimony Accumulation by Shifting the Dominant Antimony Sink from Soil Adsorption to Root-Surface Iron Plaque Sequestration

Abstract Straw return is widely practiced in paddies, yet its role in antimony (Sb) transfer from soil-to-rice remains unclear. This study compared raw straw, carbonized straw (CR), and iron–manganese-enriched carbonized straw (FMCR) to resolve dynamic coupling among rhizosphere...
