Assessment of three types of irrigation systems on leaching anions

World population growth is reaching the point where available fresh water is insufficient for basic needs of mankind. The municipal wastewater account common revival the sources for amends water deficit, since long for irrigation had used in agriculture section. For purpose of assessment of municipal wastewater of Khorasgan University (KHUW) on soil quality, four treatments in three replications were designed at 2007. The treatments were included furrow irrigation with normal water (check), furrow irrigation with KHUW (FW), surface drip irrigation with KHUW (DI), subsurface drip irrigation with KHUW (SDI). The soil samples were collected from 0-15, 15-30, 30-45 and 45-60 cm in two stages (beginning and end of research period). In this research, some parameters of soil quality were estimated. The (EC, pH, OM, Cl-,, SO2-4) parameters were measured. The results show that the wastewater increases salinity soil but there is significant difference between DI and SDI only at surface(0-15cm). Also, using wastewater does not affect soil PH. Wastewater leads to increase of OM% soil at surface (0-15 cm) with significant different between DI, SDI and FW. SO2-4 show significant difference between DI with SDI, FW at 0-15 cm of depth and there was same condition for Cl- on (0-15 cm) depth. The results indicates that wastewater reuse causes to increase EC, OM, SO2-4, Cl-. In conclusion, it was found that better condition based on EC and other salt solution in comparison with other treatments.
