Abstract
Soil, plant, and water (Kasnazan impoundment and well water) samples were monthly collected from Kasnazan (10 Km north east of Erbil city) during August 2004 to February 2005. Chemical and statistical analysis indicated that the irrigation with well water resulted to decreases EC from 0.87 dS.m-1 to 0.49 dS.m-1, because of leaching and dilution effects. Statistically there is a positive significant correlation (P< 0.05) between SAR value of well water and irrigated soil with it, whereas, a negative correlation of Mg+2 concentrations observed between well water and soil irrigated with it. On the other hand, there was high content of Mg+2 and low content of K+1 for eucalyptus plant irrigated by well water in comparison to that irrigated with impoundment water.
