Influence of Land Use on the Distribution of Some Soil Chemical and Physical Parameters in Omidiyeh, Iran

To study the effect of land use on soil properties in the south of the Omidiyeh in Khuzestan province sampling depth of 0 to 30 cm at 6 users (forest, abandoned land, irrigated farming, rangeland, dry farming and orchards) was attempted. Some physical and chemical characteristics of the soil such as saturation percent, conductivity, reactivity, and tissue were tested. Results of statistical analysis showed the type of user have a significant effect on these indicators. Although the soil in the studied area has a good texture but it is at risk of salinity. Saturation percent of the soil is also less than 50% and soil reaction is between 7/3 - 7/7. Comparison of research results and statistical analysis showed that soil quality indicators in rangeland have degraded compared to irrigated cultivated lands and soil degradation was greater in these lands.
