Abstract | Human have been thought to properly use soil and water to provide food and to prevent damages of floods in most parts of the world. Also in Iran the thought of using flood water by collecting and spreading it on the land as well as artificially recharging ground water have also been developed the same as other countries. Therefore in oreder to determine the effect of flood on fertility of soil, and also to prevent reciprocal probable harmfull effect of flood in the spreading areas, study on the effect(s) of flood water spreading seams to be essencial and imprative. Having this in the mind as a background, a study on the effect of flood water spreading in physical and chemical properties of soil in Imamzadeh Jafar-e- Ggchsaranregion, where a flood water spreading project have already been implemented, was conducted. During three years of study, soil samples were taken from 3 soil dephs including 0-15 , 15-30 and 30-45 cm of soil depth of first 3 bands of flood spreading network. The result of variance analysis of the data shows that, the effect of flood spreading on the increase of Clay , Magnisium, Potasium, Organic carbon, Saturating percent, Cation exchange capaaty (CEC) and on the decrease of Silt and Sand percent, exchangables sodium percentage (ESP) , exchangable Sodium (Ex, Na) and amount of total lime of soil in flood water spreading area in comparison to the control area, were significant at 1 to 5% confidence level. Based on the obtained results, it can be concluded that flood spreading can lead to significant positive changes on soil fertility as well as coasing to increase of Nitrogen, Chlorine , Nitrate , Sulphate and Bi -- carbonate of soil. But it should be noted that change in the last mention elements were not significant in the study area. |
