【 摘 要 】

The main driving force for eutrophication of water bodies are biogenic elements (compounds of nitrogen, phosphorus, carbon). These elements are the most important components of natural waters, which determine biological productivity. In this work, an approach based on taking into account hydrometeorological values is developed with the aim of limiting the entry of nutrient elements into the surface with runoff from agrarian lands (for example, the Kazanka River). The results of a joint analysis of the temperature and atmospheric precipitation regime, the dynamics of nitrogen and phosphorus fertilizer application, and the concentrations of nutrients in the water of the river Kazanka are given. Regression equations describing the dependence of the concentrations of nutrient substances on the investigated factors are obtained.
