Abstrakt: It is well-known that soil allelotoxicity and the water stability of soil structure are determined by the entry of plant residues into the soil, but the relationship of these soil properties has not been investigated. Soil samples from the fields of the Federal Research Center "Nemchinovka" after growing 25 cultivars of spring and winter wheat on plots with sod-podzolic soil are selected in this study. The effect of the soil's allelotoxicity of plot samples on the germination of spring wheat seed of the Liza cultivar is studied by the biotesting method. The water stability of the soil structure is determined for the same samples. The existence of a sigmoid dependence between the allelotoxicity of soil samples and their water stability with a correlation greater than 95% is established. The presence of this dependence is apparently related to the increase in the soil's water stability with an increase in the amount of fresh plant residues entering them, which is known from the literature, and the transition of the allelotoxins' effects from stimulation to suppression with a growth in their concentration in soils.
