Core Ideas We studied how alternate wetting and drying (AWD) water management effects methylmercury (MeHg) dynamics in rice fields. Alternate wetting and drying reduced MeHg concentrations in soil, water, and rice grain. Iron speciation indicated that AWD oxidized the soil and regenerated electron a...
