The object of research is the process of accumulation of radionuclides in Duke blueberry variety grown on radioactively contaminated soils of Polissia. The purpose of the work is to investigate the influence of mulching materials on the transfer of radionuclides to plants. Research methods are generally accepted for the study of qualitative and quantitative features of species and the action of agricultural methods, measuring - weight; laboratory - analytical method of product quality assessment and research of physico-chemical parameters of the soil; analysis method - study of the object of research, methods of determining the density of radioactive contamination of soil and plants, calculation - comparative, mathematical and statistical processing of the obtained research results. In 2023, research established that: the use of sawdust as a mulching material in a layer of at least 10 cm provides an optimal hydrothermal regime and contributes to the reduction of the specific activity of radionuclides and their transition into the organs of the blueberry plant. On artificially simulated soil with a high level of radiation pollution (1110 kBq/m2) in lysimeter growing conditions, the pH level fluctuated between 3.9-4.5, which created optimal conditions for the growth and development of both plants and mycorrhizae. Adding physiologically acidic mineral fertilizers to the soil (ammonium sulfate, ammophos, potassium sulfate, magnesium sulfate, monopotassium phosphate) reduced the specific activity of radiocesium in the soil by 30%, compared to the control option. On a high radiation background, the transfer of radionuclides from the soil to plant organs was differentiated, namely, when using the specified fertilizers, the specific activity of 137Cs in the aerial part (115 Bq/kg-stem and Product Description popup.authors Liabakh Serhii V.
