Soil or relative percentage of sand, silt and clay reflects some texture characteristics such as permeability, water holding capacity, CEC, and soil behavior in return to the plow and other tillage operations is very important. The study area covers an area of 1715.4 hectares, near the Aiej soil dam, East of Jooneghan city, Chaharmahal and Bakhtiari Province. For this study, 40 disturbed soil samples were collected from the area. Air dried samples were crushed and passed through a 2 mm sieve. The aim of this study is to evaluate the effect of lime removal on the particle size percentage of surface soils in some parts of studied area. In this study, tissue was determined by gauging Baykas. To evaluate the impact of the removal of lime on the soil components, Paired-Samples T-Test statistical method was used at level 0.05. The results showed that the removal of lime has a significant influence on the amounts of clay, silt and very fine sand particles, but does not have such a significant effect on the sand grains. Mechanical analysis of the soil after the removal of calcium carbonate also showed that very fine clay and sandy soils, significantly decreased, while the silt soils increase. Sand has not significantly changed. The problem can be solved with this assumption that the calcium carbonate clay and sand very fine soils are mostly dissolved within lime removal process. Therefore, the amount of clay and fine sand gains reduce, but the silt increases.
