摘要：This study was conducted in order to know the relationship of the time duration and amount of the water required for leaching Shura soil and Sabakh soil with the view of comparing the two soils.To achieve this purpose, Shura soil was collected during the commencement of the Agricultural Delmach project in Wasit city / AL-Ahrar region, and Sabakh soil during the final stages of the same project above with depth of ( 0 - 30 )cm. The two soils were leached using drain water (EC 3.7 dsm-1) and distilled water as a control unit using Miscible Displacement method, then the soils were leached for ten times durations, each one lasting (15 min.), thus the total time of duration is (150 min.), every time stage determined by extracting the pH and EC.Results showed : the duration (150)min and the required amount of water ( 150 ml ) for leaching Shura soil to decrease EC under 4 dsm-1 compared with Sabakh soil which require amount of water (60 ml ) with time stage ( 60 ) min for decreasing EC under 4 dsm-1 with significantly different between the two soils ( L.S.D/0.05). And pH decreased at every time stage with the decrease of EC until it reached the stable stage pertaining to the final time stages of the leaching operation .
