Abstracts: Problem statement: Fertilizer contamination due to accidental spillage or leakage brings hefty damage to the environments. It percolates steadily into subsurface environments and contaminates the soil and water system. Hydrocarbon contamination has not just affected the quality of the soil but will also alter the physical properties of fertilizer-contaminated soil. Approach: This study presented the geotechnical properties of fertilizer-contaminated soils as well as uncontaminated soils for comparison. Testing programs performed on the studied soils included basic properties, Atterberg limit, compaction, unconsolidated untrained triaxial test, unconfined compressive strength test, and CBR test. The silty soils used procured from parul institute of engineering and technology from vadodara, Gujarat. Soil samples were artificially contaminated with 2.5 and 5% urea of the dry weight of silty soils. silty soils might be used for geotechnical purposes and these results will benefit to engineers or decision makers in recycling or re-using of contaminated soils.
