Title

EFFECT OF IRRIGATION WITH RAW AND TREATED WASTEWATERS ON CHEMICAL CHARACTERISTIC OF SOIL IN DIFFERENT DEPTHS UNDER CONTINUOUSLY AND INTERMITTENT FLOOD CONDITIONS

Pages

  73-85

Abstract

 Soil is a dynamic environment which continuously affected by physicochemical and biological changes. Therefore, it is obvious that application of municipal wastewater may influence different properties of soil, especially it(s chemical characteristics. Thus, to evaluate the impact of waste water type and it's mode of application on some chemical properties of soil at different depths, an experiment was performed using polyethylene cylinders (11 cm diameter and 150 cm height) in a factorial statistical design with three replications. RAW SEWAGE AND TREATED EFFLUENT (from Parkandabad Treatment Plant in Mashhad) were added to the columns filled with sandy loam soils under CONTINUOUSLY AND INTERMITTENT FLOOD CONDITIONS in 7 periods of 15 days. At the end of experiment, soil samples were taken from 0-25, 25-50, and 50-100 cm depths. The results showed that parameters such as soil Salinity, Sodium Adsorption Ratio (SAR), Nitrogen (NO-3) and Phosphorus (PO-24) Total Organic Carbon (TOC) and two heavy metals (Nickel and Cadmium) increased due to application of RAW SEWAGE AND TREATED EFFLUENT, although pH decreased in the soil solution. The experiment showed that average soil Salinity, SAR, NO-3 PO-24 and Ni were significantly higher in raw sewage as compared to treated effluent. There was not a clear difference between pH, TOC and Cd among wastewaters used. Mode of wastewater application had significant effect on soil Salinity, PO-24 and Cd. The average amounts of these parameters were higher in continuously compared to intermittent application. Based on the above results, wastewater application needs special management whatever the objective might be. So that by sound usage of wastewater, environmental impact risks are reducing to the lowest levels in soil, plant as well as surface and ground water resources.
