Geochemically targeted valorization of rice straw decouples selenium recovery from cadmium transfer with climate co-benefits.
Recycling crop residues is central to sustainable agriculture, yet residues co-enriched in beneficial trace elements and toxic metals create a fundamental trade-off between resource recovery and contaminant re-entry. Here, guided by regional evidence of selenium (Se) - cadmium (Cd) co-occurrence in paddy soils and rice...
