Leveling is a process of cutting and filling in which soils of higher parts are placed in lower parts. Under this replacement some physical, chemical and biological properties of soil surface will be changed. This study aims to investigate the effect of laser land leveling on some physical and mechanical properties of moderately coarse and fine textured soils. The measurements were carried out on three different times in Lavark and Khazaneh Experimental Farm stations. The study plots were 40×90 m and were grided in 10×10 m, totally 50 grid points. The soil samples were taken at each grid point. The results were analyzed by statistical and geostatistical procedures and the map of spatial variability for the measured properties were drawn using kriging method (interpolation approaches) in GS+ software. To determine the effect of tillage management on two different times after leveling, the mean weight diameter (MWD) was estimated at higher parts of the cut field. Results showed that penetration resistance of the soils subjected to leveling, increased significant ( p 0.05) with time. Despite our expectation soil bulk density did not show any significant changes with time. The result also indicated that soil particle distribution was not affected by leveling process.
