Abstract
The article shows that the mass use of industrial nitrogen fertilizers has doubled the nitrogen flows in its global biogeochemical cycle, while transforming it into an agrogeochemical one, with many environmental consequences. Th e article discusses the ecological risks associated with the use of nitrogen fertilizers, such as the accumulation of nitrates in groundwater, vegetable products, in the atmosphere. It is shown that it is necessary to reduce nitrogen losses during the cultivation of agricultural crops, while ensuring its suffi cient resources to ensure food security. Methods of ecological risk management in modern agroecosystems are proposed.
