Harnessing the Microbial Iron Redox Chain: Liquid Organic Acid Fertilizer and EDTA-Fe Drive Unexpected Cadmium Passivation in Alkaline Upland Soils

Abstract The immobilization of cadmium (Cd) in weakly alkaline upland soils, a major agricultural system in northern China, remains a challenge. This study examined whether liquid organic acid (OA) fertilizer and EDTA-Fe could stimulate Fe redox to stabilize Cd. OA fertilizer (ac...
