During the research period 2022-2024, in conditions of gray forest soils, with agrochemical properties: exchange acidity - 5.5-5.7 units, humus content - 2.58-3.69%, mobile phosphorus and potassium, respectively, 285-342 and 178-194 mg/kg, Vygonichsky district of the Bryansk region in crop rotation studied the effect of organic and mineral fertilizer on the balance of nutrients when cultivating sugar beets. As a result of studies conducted in different agroclimatic conditions, it was found that the elemental composition of the air-dry mass of natural grass stock depended on agroclimatic conditions, the amount of fertilizer used. We found a trend of increasing the content of basic nutrients with an increase in fertilizer standards. It was found that the removal of nutrients mainly depended on the yield, the elemental composition of the air-dry mass had little effect. It was determined that the cultivation of sugar beets without the use of fertilizer causes a negative balance of basic nutrients. The use of mineral fertilizer in the studied standards allows to ensure a deficit-free balance of nitrogen and phosphorus, and the use of organic fertilizer causes a deficit-free basic elements of nutrition.
