“…The Mg 2+ absorption by plants can decrease its levels in the soil, even under wastewater irrigation, as verified by Fonseca et al (2005) for Zea mays. Also, wastewater often contains solutes that can form magnesium precipitates, decreasing its availability.…”

Agricultural use of wastewater is an alternative to increase water availability, especially in semiarid regions. However, it may cause undesirable chemical changes in the soil. The aim of this study was to evaluate the influence of wastewater irrigation and castor bean (Ricinus communis L.) cultivation on the chemical attributes of a Fluvic Neosol. The experimental design was in a randomized block, in split-plot scheme, where the main plots were represented by the treatments of irrigation water and castor bean cultivation, and the subplots were the soil layers, with three replications. The treatments were T1 -wastewater irrigation + castor bean cultivation ; T2 -mixture of supply water and wastewater (1:1 ratio) + castor bean cultivation; T3 -supply water irrigation + castor bean cultivation ; and T4 -wastewater application, without castor bean cultivation. The depths of soil layers were 0-10, 10-20, 20-30, 30-40, and 40-50 cm. At the end of study, the content of phosphorus, calcium, potassium, and organic matter increased mainly in the upper layers, and sodium increased in the deeper layers in the wastewater treatments, in comparison to the supply water irrigation. In T4, the disposal of wastewater increased the concentration of magnesium. The pH values, iron and zinc concentration did not statistically differ in the treatments.

“…These changes may result in significant impacts in the soil quality (Fonseca et al, 2005;Herpin et al, 2007), or may not (Varallo et al, 2010;Duan et al, 2010). Thus, the soil chemical attributes must be continuously monitored (Leal et al, 2009b).…”

“…As proved decrease of soil pH could increase the uptake of heavy metals by plant (Fonseca et al, 2005b), so decrease of soil pH in WW treatment (Table 6), increased uptake heavy metals by the sunflowers. These results were consistent with the conclusions by Mojiri and Hamidi (2011).…”

“…Treated municipal wastewater may prove a potential economic asset by contribution to saving water resources, irrigating agriculture land and even reducing fertilizer inputs (Fonseca et al, 2005b). In fact, the reuse of treated municipal wastewater in irrigation is an alternative to water scarcity and a means of environmental protection by reducing the discharge of water into rivers and oceans (Zavadil, 2009).…”

“…This concern encouraged the researchers to study the pollution levels of heavy metals in the plant to determine their permissibility for human consumption. It seems that, choice of crops for treated wastewater irrigation is the principal factor for the suitability of effluent irrigation because certain crops could be irrigated without negative implications on yield (Fonseca et al, 2005b). Sunflower (Helianthus annuus L.) is an increasingly important source of vegetable oil and biomass, usefully employed for food, chemical, energy, and industrial purposes (Riva and Calzoni, 2004).…”

Treated wastewater could be considered as a new water resource in agriculture especially in arid and semi-arid regions of the world such as Iran. Two one-year field experiments were carried out to determine the effects of municipal treated wastewater on yield and seed heavy metals content of sunflower cultivars, in Research Farm of Yazd Municipal Wastewater Purification Station during 2015 and 2016. The climate of the region was hot and dry according to Koppen climate classification system. Experiment was arranged as split plot based on randomized complete block design with three replicates. Treatments were three irrigation water types as main plot consisted ("WW": irrigation with treated municipal wastewater thoroughly, "WW/FW": irrigation with treated wastewater/fresh water alternatively and "FW": irrigation with fresh water thoroughly) and three sunflower cultivars (Azargol, Record, and Farrokh) as subplots. The following parameters were assessed: plant height (cm), head diameter (cm), seed numbers per head, unfilled seeds per head, seed and biological yield (kg/ha) and seed heavy metals content. Results showed that the highest plant height (194 cm) obtained in Record and the highest head diameter (21.5 cm) obtained in Farrokh cultivars, which were irrigated by WW. Treated municipal wastewater also increased seed yield by 10.7% compared to FW treatment. The highest (5029 Kg/ha) and lowest (3734 Kg/ha) seed yield were obtained in Azargol and Farrokh that irrigated with WW and WW/FW treatment, respectively. However, application of treated municipal wastewater lead to accumulation of trace elements (Fe, Mn, Zn, Cu, Cd, Pb, and As) in seeds; but, the values of all the elements were below the permissible limits recommended by World Health Organization. It is concluded that WW could be used for irrigating sunflower crop without worrying about the accumulation of toxic substances.
