Abstract
All phases of oil exploitation, from the start of oil-drilling works to construction of the transport system (underground pipeline network) are accompanied by interventions and procedures hazardous to the environment. Although the state-of-the-art technical solutions and modern materials used by INA in all exploitation phases warrant a high level of safety, the possibility of different incidents is unfortunately not fully excluded. Incidents endanger natural resources, primarily soil and water, and may, depending on their severity, jeopardize for a certain length of time the intended use of the land on which the incident occurred, that is, rule out the possibility of its use for plant or livestock production. In the last two decades, the staff members of the Faculty of Agriculture Department of General Agronomy participated in the number of studies dealing with the evaluation of the extent of contamination of soil on which an oil incident occurred and drew up studies and plans for remediation of such soils. The paper presents the results of threeyear-long research on growing winter wheat (Triticum aestivum L.), winter barley (Hordeum vulgare L.) and soybean (Glycine hyspida L.) in pots under different degrees of soil contamination by oil. Research involved monitoring of changes in the soil chemical complex (pH, changes in plant available phosphorus and potassium, content of organic matter); also monitoring of number of plants, achieved yields and studying chemical changes in plant material caused by different degrees of soil contamination.
