Abstract

In this study, we tried to study the effect of water spreading on some soil chemical properties in the study region. For this purpose, seven sections of water spreading area were selected and each section was divided into three parts. Soil samples were taken in four replicates from the middle of the three parts at 0-25 and 25-50 cm depths. Then, the samples were mixed. The parts of the study area that did not receive flood water were cosidered as the control. Soil sampling method in the control area was similar to other treatment areas. All samples were analyzed in the laboratory. The results showed that there was significant decrease in pH and LIME CONTENT at 1% and 5% level, respectively. Also, there was significant (at 1% level) increase in organic carbon, organic matter, and electrical conductivity of saturated extract in the top soil (0-25 cm) in the control area compared to the plots receiving flood water. Thus, the results showed significant (at 1% level) reduction in EC and significant (at 5% level) decrease in pH in areas with flood water distribution, but there was no significant difference in LIME CONTENT of sub surface soil.
