“…Bedbabis et al (2010) analyzed the effects of irrigation with treated effluents along 2 years in a sandy soil cultivated with olive trees in Tunisia and observed that the application of wastewater promoted greater accumulation of Mn and Zn in the soil, compared with the management with good water quality. Lado et al (2012), however, report that soils with similar texture irrigated with secondary effluents for 7 years showed lower Fe contents and Cu and Zn contents similar to those observed under the application of freshwater.…”

“…Studies conducted over a longer period and/or with effluents containing higher P contents, however, have reported considerable accumulations of the nutrient in the soil, notably in the subsurface layers of sandy soils (Rusan et al, 2007;Lado et al, 2012;Bame et al, 2014). The P added to the soils by the domestic sewage effluents is essentially found in the forms of orthophosphates (inorganic P) and organic phosphates (organic P), which are available to plants only after conversion to inorganic assimilable forms (Havlin et al, 2013).…”

“…According to Arienzo et al (2009), the K added to the soil through the disposal of wastewater has low levels of leaching, which causes the portion not absorbed by the plants to accumulate in the soil for long periods. Studies have also shown that, due to the low mobility of K ions in the soil, larger amounts of the element concentrate in the most superficial layers of the profile (Lado et al, 2012;Bedbabis et al, 2014).…”

“…As to boron, most studies that mention its dynamics in areas of reuse have reported the increase in its contents in the soil resulting from the application of sewage effluents (Lado et al, 2012). According to Ben-Hur (2004), B sources in domestic wastewater include human feces, household detergents and powdered soap.…”

The objective of this research was to investigate the effects of irrigation with treated wastewater and nitrogen (N) fertilization on the chemical characteristics of a Haplustalf soil cultivated with cotton. An experiment was conducted in a greenhouse in a completely randomized design with four replicates, and arranged in a 5 x 4 factorial. Five doses of N fertilization (0, 45, 90, 135 and 180 kg ha-1) and four sources of irrigation water (freshwater, wastewater treated by an anaerobic reactor, wastewater treated by an anaerobic reactor and post-treated by intermittent sand filter in series, wastewater treated in a septic tank and post-treated by an intermittent sand filter) were tested. Irrigation was daily performed from July 2011 to January 2012 according to the water demand of cotton resulting in a water depth of 620 mm. It was found that, compared with the conventional management with freshwater irrigation, treated wastewater provides greater accumulation of micronutrient, potassium and sodium in the soil, increasing the risk of sodification in irrigated areas.

The challenge of meeting the projected doubling of global demand for food by 2050 is monumental. It is further exacerbated by the limited prospects for land expansion and rapidly dwindling water resources. A promising strategy for increasing crop yields per unit land requires the expansion of irrigated agriculture and the harnessing of water sources previously considered ''marginal'' (saline, treated effluent, and desalinated water). Such an expansion, however, must carefully consider potential long-term risks on soil hydroecological functioning. The study provides critical analyses of use of marginal water and management approaches to map out potential risks. Long-term application of treated effluent (TE) for irrigation has shown adverse impacts on soil transport properties, and introduces certain health risks due to the persistent exposure of soil biota to anthropogenic compounds (e.g., promoting antibiotic resistance). The availability of desalinated water (DS) for irrigation expands management options and improves yields while reducing irrigation amounts and salt loading into the soil. Quantitative models are used to delineate trends associated with long-term use of TE and DS considering agricultural, hydrological, and environmental aspects. The primary challenges to the sustainability of agroecosystems lies with the hazards of saline and sodic conditions, and the unintended consequences on soil hydroecological functioning. Multidisciplinary approaches that combine new scientific knowhow with legislative, economic, and societal tools are required to ensure safe and sustainable use of water resources of different qualities. The new scientific knowhow should provide quantitative models for integrating key biophysical processes with ecological interactions at appropriate spatial and temporal scales.
