The coefficient of variation of the total С-СО2 emission was smaller, and the distribution asymmetry coefficient had a positive value and deviated little from the center of the distribution of the parameter, which indicates the stabilization of С-СО2 emission from the mineralization of humus and by-products at a significantly lower level compared to the intensive fertilization system, which indicates the stabilization of humus chernozem in agrocenosis. Under the organic fertilization system, the distribution of N in the structure of the total phytomass: 26% – main products, 30% – by-products, 44% – roots; for non-marketable products - 74% N, and for 1 t N of the main product there is: 0.17 t/ha N of secondary products, 1.76 t/ha N - root mass or 2.96 t/ha N - non-marketable part of the total phytomass . There is a redistribution of the N reserve in favor of the non-commercial share of the total phytomass, the part of which increases by 1.15 times, and relative to the root mass by 1.21 times. It was established that under the organic system of fertilization, the ratio of carbon monoxide to nitrogen in the agrocenosis of short-rotation crop rotation is the most optimal and approaches 30 to 1, which is the most beneficial for the humification of by-products and the reduction of the intensity of humus mineralization. The limiting factor in the circulation of carbon monoxide and nitrogen under the organic system is the balance capacity, which under the organic fertilization system is significantly inferior to the balance capacity under the intensive fertilization system, which negatively affected the productivity of crop rotation.
