The article presents comparative data on the content of sulfur, phosphorus, nitrogen, ash in the leaves of perennial and annual ornamental plants, such as-Hemerocallis hybrida, Iris hybrida, Hosta lancifolia, Salvia splendens, Tagetis patula, Senecio cineraria, Gatsania hybrida, Alyssum hybrida, grown in flower beds near road and industrial zones of the city. Iskitim's. The change in the concentration of substances within each type is shown in the direction of increasing indicators in the series: S<P<N< - ash. The specificity of the content of elements for each type is revealed. It was found that the content of sulfur, phosphorus, nitrogen, and ash in these plants differs by ambiguous indicators in an urbanized environment. It was determined that in the flower beds of industrial zones, the nitrogen content in the leaves of annual plants such as alissum, Salvia splendens, Senecio cineraria was 6–11 times higher compared to sulfur and phosphorus. It was found that the nitrogen concentration is 2.5–3 times lower in perennial plants compared to annual ones. In the leaves of Hemerocallis hybrida, growing 50 m from the road, the ratio of S:P:N, sulfur is 1.5 times higher than in plants growing 100 m from the road. It was found that the distribution of sulfur, nitrogen, phosphorus, and ash in the leaves is species-specific.
