Abstract

Different viscosity and dielectric constants in petroleum productscause physicochemical interactions in the porous fluid electrolyte system, followed by changes in the physical and mechanical properties of the soil. Shear strength of surface soil is one of the most important mechanical properties influencing determination and prediction of soil erosion as a global problem. Penetration resistance is also another mechanical properties of soil that affects tillage operations, plant growth, and soil biological activities and has an important role in seed germination, root growth and development, and crop yield. This study aimed to investigate the effect of application of 0, 1.5, 3.5, and 4.5% of three types of common petroleum products including crude oil, kerosene, and gasoline on shear strength and penetration resisstance of three calcareous soils with clay loam, loamy sand, and sandy loam textures. Results showed that the mean value of shear strength in loamy and sandy loam soils compared to that of clay loam soils was significantly higher by nearly 100 and 35%, respectively, and the penetration resistance in loamy sand soils compared to that of clay loam and sandy loam soils was significantly lower by nearly 83% and 88%, respectively. The mean value of shear strength in soils mixed with kerosene and gasoline compared to that of the soils mixed with crude oil was significantly higher by nearly 17 and 15%; and penetration resistance was significantly higher by nearly 61 and 53%, respectively. In general, the application of 1.5, 3, and 4.5% of oil products caused a significant increase in soil shear strength by about 58, 47, and 14%, respectively, and also caused a significant increase in soil penetration resistance by about two times in all cases compared to that of control.
