Performance of forest tree Khaya senegalensis (Desr.) A. Juss. under sewage effluent irrigation

Losses of ammonia (NH3) following sewage effluent irrigation of pasture were measured under different climatic conditions at Wagga Wagga, New South Wales. Ammonia volatilisation was measured by the micrometeorological mass balance technique using 2 different passive samplers, and by an indirect technique based on the measurements of ammoniacal-N (NH4+ + NH3) concentration, pH, and temperature of the soil solution in the 0–3 mm soil layer, and wind speed at 1.2 m above the soil surface. Maximal NH3 emission rates were measured directly following the effluent-irrigation. There was reasonable agreement between the 2 different passive gas samplers used to measure NH3 volatilisation. The NH3 volatilised was well related to the product of wind speed and the equilibrium ammonia concentration (calculated from the soil solution measurements) as was found in other studies. In addition, NH3 flux density was strongly related to evaporation; that is, when the water (effluent) evaporated NH3 was lost to the atmosphere. Under high evaporative conditions, a maximum of 24% of the ammoniacal-N in the effluent was lost by volatilisation within 2 days of application.

A surface sample representing a high contaminated loamy sand soil irrigated with sewage effluent since 30 years and was cultivated with artichoke was collected from Abu-Rawash sewage farm. The existence of HVC, enteric infectious bacteria and parasites in sewaged soil found to be negative for the forward and positive for the latter's. Out of the 30 samples separated from the sewaged soil sample, only 3 samples contained parasitic fauna of developed and undeveloped Ascaris (10%) and five samples contained Entamoeba coli. Results showed that the number of Ascaris eggs/gm soil was 0.017 and the number of E. coli/gm was 0.26. Decontamination of soil parasites was effective using either calcium hypochlorite or potassium permanganate. Salmonella, Vibrio and Campelobacter were detected in the high contaminated sewaged soil and survived for 120 days in the sewaged soil under all control and bioremediated treatments irrigated with either sewage effluent or water.
