Can Potato Crop on Sandy Soil Be Safely Irrigated with Heavy Metal Polluted Water?

Heavy metal (HM) accumulation in soil and plants can occur when water contaminated with HMs is used as a source of irrigation (El-Salam Canal, Egypt). In this study, the effect watering potato crop sandy from polluted under flood (FI), sprinkler (SI), surface drip (DI) on transport copper (Cu), manganese (Mn), lead (Pb), zinc (Zn) root zone was experimentally investigated. HM concentrations plant parts also determined. The field experiments were conducted completely randomized block three replicates for each method by using nine lysimeters. Soil samples collected at end growing season to determine their content. results showed that regardless method, raised both plants. DI produced highest most (Cu, Mn, Pb) upper layer (0–40 cm) Cu, Pb, Zn tubers well. Maximum concentration maximum Mn occurred SI. 12.0, 140.0, 11.6 67.9 mg/kg 6.3, 9.4, 2.3 23.9 mg/kg, respectively. However, FI deep (40–60 least tubers. These 18.8, 203.8, 13.3 70 4.0, 6.0, 0.6 17.1 Zn, lower than permissible limits. Therefore, El-Salam Canal appears not be harmful short term. shown results, depends technique; thus, more studies are needed effects long
