THE IMPACT OF SOIL POLLUTION BY OIL ON THE CONTENT OF HUMIC SUBSTANCES

Abstract

The research assesses the impact of oil contamination on soil humus substances. Laboratory experiments with varying concentrations of petroleum products on different soil types revealed that even small amounts of oil lead to significant degradation of humus substances, altering their structure and reducing their content. These changes may disrupt soil properties, diminishing fertility, structure, and water retention capacity, and reducing microbial activity. Understanding this influence is crucial for developing strategies to rehabilitate polluted soils and sustain ecosystems.
