The article presents materials on the impact of the use of mineral fertilizers and various norms of manure on the nitrogen balance in the short-rotational rotation “cotton-winter wheat”. It is shown that when using only mineral fertilizers, the nitrogen balance is formed with a deficit. When using manure at a rate of 10 t / ha in combination with mineral fertilizers, there is a deficient nitrogen balance. With an increase in the manure rate to 20 t / ha and its combination with mineral fertilizers, a positive nitrogen balance in the “soil-fertilizer-plant” system is ensured.
