“…According to the report of the Pakistan Council of Research in Water Resources (PCRWR, 2004), only 1% of the industrial effluent from Pakistani industries is treated before being discharged into rivers or other drains; consequently, an excess concentration of arsenic and fluoride has been reported in the water supplies of six major cities. The use of industrial wastewater for growing trees and agricultural crops has been suggested to be a cost-effective way to nurture plants as it eliminates the need for commercial fertilizers (Marecos do Monte et al, 1989). However, when soil is exposed to such wastewater on a consistent basis, it causes drastic changes to the soil properties, such as pH, electrical conductivity (EC), and nutrient availability (Russell et al, 1988).…”

ABSTRACT. Biofuel tree species are recognized as a promising alternative source of fuel to conventional forms. Additionally, these 9544 S.A. Manzoor et al. ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (3): 9543-9554 (2015) tree species are also effective in accumulating toxic heavy metals present in some industrial effluents. In developing countries such as Pakistan, the use of biofuel tree species is gaining popularity not only for harvesting economical and environmentally friendly biofuel, but also to sequester poisonous heavy metals from industrial wastewater. This study was aimed at evaluating the genetic potential of two biofuel species, namely, Jatropha curcas and Pongamia pinnata, to grow when irrigated with industrial effluent from the Pak-Arab Fertilizer Factory Multan, Southern Punjab, Pakistan. The growth performances of oneyear-old seedlings of both species were compared in soil with adverse physiochemical properties. It was found that J. curcas was better able to withstand the toxicity of the heavy metals present in the fertilizer factory effluent. J. curcas showed maximum gain in height, diameter, and biomass production in soil irrigated with 75% concentrated industrial effluent. In contrast, P. pinnata showed a significant reduction in growth in soil irrigated with more than 50% concentrated industrial effluent, indicating that this species is less tolerant to higher toxicity levels of industrial effluent. This study identifies J. curcas as a promising biofuel tree species that can be grown using industrial wastewater.

“…However, only 24% of the available treated wastewater is used, which could be evolved. The reuse of treated wastewater is generally considered beneficial for crop production and, as a result of its nitrogen content, can help to reduce the requirements for commercial fertilizer [1,13,18,22,27,40,41]. However, both nitrogen deficiency and N excess, especially early and late in the growing season, can reduce crop yields.…”

Wastewaters are increasingly used for irrigation of cropping systems in Tunisia. However, to develop environmentally sound practices the contribution of wastewater to crop N nutrition needs to be clarified, especially in cropping systems already receiving mineral fertilizers. For a better understanding of the interaction between fertilizer N and N originating from wastewater, experiments using 15 N were conducted. 15 N-labeled fertilizer was applied at different rates (0, 60, 100 and 140 kg N•ha-1) and with different water irrigation qualities (tap water or treated wastewater) to sorghum grown in lysimeters during 1998 and 1999. Recovery of 15 N-labeled fertilizer in the above-ground crop at final harvest in treated wastewater irrigation was higher at the lowest rate of fertilizer application (54%), with the amount recovered in the crop increasing as the rate of 15 N-labeled fertilizer application increased up to the rate of 100 kg N•ha-1. Nevertheless, in spite of this increase in 15 N-labeled fertilizer in the crop, total plant N uptake did not differ between rates. Treated wastewater irrigation had no negative effect on the recovery of 15 N-labeled fertilizer. About 62 and 55% of 15 N-labeled fertilizer was removed by Sudangrass in either tap water or treated wastewater. Neither fertilizer N rate nor water quality had an effect on the 15 N-labeled fertilizer remaining in the soil at final harvest. On average 20% in the wastewater treatment (19-24%) and 30% in the tap water treatment (26-31%) of the 15 N fertilizer applied were in the 0-60 cm layer of soil at final harvest in 1998 and 1999, respectively, and mostly present in the 0-20 cm layer. The proportion of applied 15 Nlabeled fertilizer remaining in the soil at final harvest increased with increasing N rates. About 60, 69 and 72% of 15 N left in the soil at final harvest was in the surface 0-20 cm layer. Residual 15 N was greatly higher in soil following the first harvest than after the final harvest, with the greatest value (38%) measured at the lowest rate of 15 N-labeled fertilizer (30 kg N•ha-1). Losses of 15 N-labeled fertilizer increased with application rate, but were unaffected by water quality irrigation. Approximately 13% of the applied 15 N fertilizer was lost following the application of 100 kg N•ha-1 with either treated wastewater or tap water irrigation.
