Innovations in the application of nitrogen fertilizers in agrocenoses

The article presents materials on the innovative technology of nitrogen fertilizers application in the cultivation of winter grain crops, which is the most effective way to increase the yield.Differentiated application of mineral nitrogen in accordance with the vegetation index NDVI and the amount of absorption of this nutrient will allow crop agrocenoses to use nutrients more efficiently, increase yields, reduce the anthropogenic load on the environment, and improve the environmental friendliness of the grown products.On average, over the years of research (2023-2024), the control with a uniform distribution of nitrogen fertilizers yielded 8.67 t/ha of winter wheat, and with differentiated nitrogen fertilization application using the Yara N-Sensor device -9.32 t/ha.The yield increase was 0.65 t/ha or 6.5 %.As of October 2024, the purchase price of wheat grain was $ 206 per ton, and given the yield increase of 0.65 t/ha, the additional cash flow per unit of sowing was $ 133.9.To pay off the Yara N-Sensor device, which costs $ 40,000, the farm needs to use it on an area of 299 hectares per year.
