“…Similar estimates were observed by Hölscher et al ( 1996 ) with a nutrient output of K (61 %) and P (62 %) (Table 6 ). Based on a study by Korom and Jeppson ( 1994 ) about 24 % of the N and 0.2 % of the TP applied leached through the soil zone of the sewer farm. Similarly, a study by Geber ( 2000 ) found that the amount of N removed increased with increased nutrient load.…”

This study evaluated the effects of abattoir wastewater irrigation on plant growth and development. The soils used in this study were collected from Primo Smallgoods Abattoir (Port Wakefield, South Australia) at different sites such as currently irrigated (CI), currently not irrigated (CNI) and soil outside the irrigation area as control (CTRL). A completely randomised block design was employed for the plant growth experiment, where four crops (Pennisetum purpureum, Medicago sativa, Sinapis alba and Helianthus annuus) were grown separately on three different soils (CI, CNI and CTRL) in plastic pots. Two types of water (tap water and wastewater) and two loadings were applied throughout the planting period based on the field capacity (FC 100 and 150 %). The overall dry matter yield was compared between the soils and treatments. Under wastewater irrigation, among the four species grown in the CI soil, P. purpureum (171 g) and H. annuus (151 g) showed high biomass yields, followed by S. alba (115 g) and M. sativa (31 g). The plants grown under tap water showed about 70 % lower yields compared to the abattoir wastewater irrigation (AWW). Similar trends in the biomass yields were observed for CNI and CTRL soils under the two water treatments, with the biomass yields in the following order CI > CNI > CTRL soils. The results confirm the beneficial effects of AWW at the greenhouse level. However, a proper cropping pattern and wastewater irrigation management plan is essential to utilise the nutrients available in the wastewater-irrigated land treatment sites. The increase in fertility is evident from the effects of wastewater on biomass growth and also the abundance of nutrients accumulated in plants. A mass balance calculation on the applied, residual and the plant-accumulated nutrients over a few cropping periods will help us in understanding the nutrient cycling processes involved in the abattoir-irrigated land treatment sites, which will serve as an effective tool for the environmental management.

“…Oron et al (1999) have shown the following benefits associated with the drip irrigation using wastewater: decreased water losses to evaporation, runoff and percolation; decreased weed growth, decreased pollution of soil, water and plant surfaces; improved control over irrigation delivery systems, transport of wastewater in pipes; and reduced contact of the farmers with wastewater. Korom and Jepsson (1994) showed that in a surface irrigation system with wastewater, 24% of the total wastewater nitrogen leaches from the root zone. Lauver (2000) performed a nitrogen mass balance analysis for municipal wastewater in Arizona, USA.…”

The use of municipal wastewater for irrigation needs special management. This is due to the environmental and health hazards. In this study, secondary treated municipal wastewater was used in five irrigation treatments. These treatments were as follows: furrow irrigation with normal water (FN), drip irrigation with wastewater (DI), subsurface drip irrigation in 15 cm depth with wastewater (SDI 15 ), subsurface drip irrigation in 30 cm depth with wastewater (SDI 30 ), and furrow irrigation with wastewater (FW). The results showed that the application of DI and SDI sand filters causes a decrease in wastewater index pollution, including 50.1% BOD 5 , 98.9% total count, 97.6% total coliform, 93.2% faecal coliform, 57.1% nematode, 81% total nitrogen, 52% N-NO 3 , 84% N-NH 4 and 44% total suspended solids. In addition, the application of the SDI system causes a decrease in the moisture content of the soil surface, which decreases total coliform and faecal coliform on the soil surface. The average values for these parameters show no significant difference (5% level) between SDI treatments and FN. The results of this research also show that in the case of SDI with its minimal leaching, prevalence contamination (such as N-NO 3 ) was minimized as a result of the usage of wastewater at depth and in groundwater. Moreover, in SDI treatments, the maximum EC and SAR leaching are observed at 60 cm depth, whereas in the FW this leaching is observed deeper than 90 cm. RÉ SUMÉL'utilisation des eaux usées municipales pour l'irrigation nécessite une gestion spéciale afin d'éviter les risques pour la santé et l'environnement. Dans cette étude des eaux usées municipales de l'usine d'Ispahan avec traitement secondaire ont été utilisées dans cinq traitements d'irrigation. Ces traitements étaient les suivants: irrigation à la raie avec de l'eau normale (FN), l'irrigation au goutte-à-goutte avec des eaux usées (DI), irrigation en sub-surface à 15 cm de profondeur avec des eaux usées (SDI 15 ), idem à 30 cm (SDI 30 ), et irrigation à la raie avec des eaux usées (FW). Les résultats de cette recherche montrent que l'utilisation de filtres à sable dans DI et SDI a provoqué une diminution des index de pollution des eaux usées: 50,1% de la DBO 5 , 98,9% de la quantité totale, 97,6% des coliformes totaux, 93,2% des coliformes fécaux, 57,1% des nématodes, 81% de l'azote total, 52% de N-NO 3 , 84% de N-NH 4 et 44% des matières en suspension. En outre l'application de SDI a entraîné une diminution de l'humidité de la surface du sol, ce qui a diminué les coliformes totaux et de coliformes fécaux en surface. Les valeurs moyennes pour ces paramètres n'ont révélé aucune différence significative (seuil 5%) entre les traitements SDI et FN. Les résultats de cette recherche ont également montré que avec SDI du fait d'une infiltration moindre, la IRRIGATION AND DRAINAGE y Effets de l'irrigation avec des eaux usées municipales traitées sur les propriétés des sols dans les régions arides et semi-arides. contamination de prévalence (tels que le N-NO 3 ) est min...
