This article examines the methods of biological soil cleaning in Ayyrtau District of North Kazakhstan Region. It investigates existing pollutants, sources of pollution, and the effectiveness of biological methods for restoring the ecological state of soils. The results of studies on the biological cleaning of soils in Ayyrtau District are presented. Concentrations of heavy metals, pesticides, and petroleum products were studied before and after the application of phytoremediation and bioremediation methods. The use of sunflower, alfalfa, and willow for phytoremediation showed a significant reduction in concentrations of cadmium, lead, petroleum products, and pesticides. Sunflower and alfalfa were found to be the most effective plants. In bioremediation, methods such as biostimulation, bioventing, and bioaugmentation were applied, which also demonstrated significant reductions in pollutant levels. Combined methods, combining the use of plants and microorganisms, were the most effective for soil cleaning. These methods not only reduce pollution levels but also restore soil fertility, improving the ecological situation and increasing the agricultural potential of the region. The choice of a specific cleaning method depends on the type of pollutant and soil characteristics. The study results showed that the application of phytoremediation and bioremediation significantly reduced the concentrations of heavy metals and organic pollutants in the soil. The most effective were combined methods, combining the use of plants and microorganisms. The choice of a specific method depends on the type of pollutant and soil characteristics. The conducted studies emphasize the need for an integrated approach to solving soil pollution problems, which improves the ecological situation in the region and promotes sustainable land resource management.
