The normative parameters of the organic carbon transformation model in crop rotations with different rotations have been established. During crop rotation with a long rotation, the content and stock of total humus, humus carbon, and in terms of Cg and Sorg-СО2 stocks (in terms of deposited CO2) in the 0-20 cm layer was higher by 0.14%, 0.08%, 1.3 t/ha and 4.6 t/ha, respectively, and in the 20-30 cm soil layer: 0.13%, 0.07%, respectively, of humus Cg content, while the supply of Cg and Sorghum – СО2 were equal.
For 3-5 crop rotations, 0.78 units of Sorg deposition (СО2) in phytomass were accounted for by 0.78 units of Sorg deposition (СО2) in phytomass per unit of growth, which is 1.07 times less than when the correlation level decreased to the direct average level, which provides 30% participation in the total set of interactions. The С-СО2 balance in crop rotations was deficient, and the increase in productivity of crop rotations was associated with a decrease in CO2 deficiency to 12.0–17.9 t/ha and the achievement of the balance intensity to 63.0–67.0%. In crop rotations with a short rotation, the deficiency of CO2 to a lesser extent limits the manifestation of productivity and, to a greater extent, the stock mechanism of Sorg for the formation of humus is manifested.
