| dc.description.abstract | This experiment was applied to study the effect of sludge fertilization and irrigation with treated wastewater produced from the Jenin treatment plant on the accumulation of heavy metals in vertisols soil, calcareous soil, and barley plants. The experiment was conducted in a greenhouse under controlled conditions at the National Center for Agricultural Research in Qabatia, Jenin. This study used the soil column experiment with two types of soil: vertisol soil and calcareous soil. A section of each type of soil was taken at a depth of 1 m, and then it was represented in PVC tubes (6 columns for each type of soil) with a length of 1 m and a diameter of 72 mm. Every three soil columns were arranged into lines for the experiment, with two lines for each type of soil. These lines were then connected to an irrigation network. Then 200 ml of sludge was applied to a line of each soil type as fertilizer. After that, during the following growing season of 2021–2022, three barley seeds were sown in each column. After three months of irrigation with treated wastewater, the plants were harvested, the soil columns were dried, and they were divided into three layers (1-30 cm, 30-60 cm, and 60-100 cm). The chemical analyses were used to measure the content of heavy metals (Fe, Mn, Zn, Cu, Cr, Ni, Co, Pb, Cd, and As) in plants and soil layers using an ICP-MS device. The major nutrients N, P, and K were measured in the plant samples, and the length and weight of the plant were recorded. The results showed that fertilization with sludge and irrigation with treated wastewater increased the concentrations of Fe, Mn, Zn, Cu, and macronutrients N, P, and K in barley plants. Also, fertilization with sludge increased the weight of barley plants. The results confirmed that Vertisol soil is more fertile than calcareous soil. Fertilization with sludge increased the movement of heavy metals in the soil column and their filtration into the bottom layer. Sludge can be considered a source of plant nutrients as it contains macronutrients such as nitrogen, phosphorus, and potassium and micronutrients such as iron, zinc, and manganese.
