Аннотация: Abstract—The influence of various types of impacts on soil samples on the germination of seeds and thedevelopment of seedlings in comparison with sand (allelotoxicity) was studied. It is established that various types of soil sample preparation can significantly affect their allelotoxicity. It is shown that initial soil stimulated seedling development (+23%). Drying to air-dry state with further wetting increased the allelotoxicity to –27%. Autoclaving of samples (148 C, 4.5 atm) increased their allelotoxicity to –77%. The data obtained suggest that allelotoxins can exist in the soil in active and fixed forms and pass from the fixed form to the active form under various types of impacts on the soil. The study of the influence of the allelotoxicity of soil sampleson the application efficiency of sorption-stimulating preparation (SSP), used for the pre-sowing treatment of spring wheat seeds, shows that the application effect of SSP monotonically decreases when allelotoxicity increases. The calculations show that the amount of sorbent used to protect seeds from allelotoxins is 3–4 orders of magnitude lower than the amount that can fix allelotoxins contained in soils. It follows from above that the development of seed seedlings is affected only by a small part of allelotoxins present in soils in the active state.
