An inverse strong correlation was found between the capacity of N and the ratio of C to N in agrocenosis: R=-0.81±0.02; R2=0.64, which indicates that with the strengthening of humification processes (narrowing of the ratio), there is an increase in the capacity of the organic carbon balance and a decrease in the level of the capacity of the С-СО2 balance (increasing mineralization) and is associated with a decrease in the productivity of crops in the agrocenosis of crop rotation on control without fertilizers.
