This study investigates the effects of using domestic wastewater in field experiments on Fluvisols soils in peri-urban areas of Hanoi and Nam Dinh cities. We compared long-term (30-50 years) wastewater-irrigated rice-dominated farming systems. Using wastewater for irrigation significantly affected pH, electrical conductivity (EC), exchangeable K and Na and reverse aqua regia-digestible (Rev Aq Reg) copper (Cu), lead ...
