Land leveling is a conservation solution to create a uniform slope to integrate, facilitate irrigation and drainage of paddy lands. Despite the positive effects of land leveling, it destroys the physical properties of the soil. The purpose of this study was to investigate the impact of land leveling on the physical characteristics of the soil. This work compares traditional and leveled lands, Balagafsheh and Limuchah areas, which have been leveled for two and five years, respectively. A total of 80 samples were taken, 20 soil samples from each traditional and land leveled plot in the two areas at depth of 0-20 cm by a grid method with dimensions of 20 by 20 meters.  Mean comparison was performed using an independent t-test and SPSS software. The results of comparing the mean showed a significant increase in the percentage of clay, bulk density, penetration resistance in the leveled lands of Limuchah, but in Balagafsheh area, the opposite results were observed. In general, the results indicated changes due to land leveling, such as changes in particle size distribution, structure destruction, and soil compaction without proper management after the implementation of the project, and the reversibility of soil properties is not adjusted solely by relying on the role of the time factor.. Proper management practices such as growing cover crops and returning them to the soil, such as the Balagafsheh area, can exploit the benefits of the land consolidation plan and control the destructive effects of it.
