GediFeng® Heavy Metal Passivator specifically targets and immobilizes heavy metals in soil, reducing their bioavailability and effectively blocking crop uptake. It ensures that heavy metal levels (such as cadmium, lead, arsenic, and mercury) in agricultural products consistently perform better than national standards. It is ideal for remediating heavy-metal-polluted farmland near mining areas and sewage-irrigated zones. The product holds a Fertilizer Registration Certificate from MARA of the PRC.
