Human activities play a significant role in affecting soil alterations. Alterations in land structure and utilization methods accurately reflect the socio-economic progress in each region. The drive to meet the livelihood needs of human populations is a key determinant of the degree of land degradation. This pertains not only to improper crop selection but primarily to heavy metal pollution, sewage, waste disposal, and unregulated leakage of petroleum substances. The objective of this study was to identify a suitable method for reclaiming soil contaminated with petroleum substances based on its type. Types of soils used for testing include brown soil, humus, loamy sand, clay, Vistula sand and loess. To conduct the experiments, various petroleum derivatives were prepared, including gasoline, diesel oil, heating oil, hydraulic oil and used engine oil. It was found that soils like clay and loess are highly resistant to the penetration of petroleum substances into their structures. Also we noticed that soil contaminated with used engine oil exhibited the highest level of contamination, necessitating several reclamation operations such as liming.
