We report on a long-term experiment from 1936 to 2017 in the North of the Voronezh region, located in the Central Chernozem Region of Russia. The application of fertilizers on a grain-arable crop rotation with 2 fields of sugar beet revealed that the longer fertilizers were applied, the more considerable their effectiveness was in terms of both the direct effect and the after-effect. Regarding the after-effect, barley was the most responsive crop; its average yield increased by 18–36% over the period under investigation. The least reaction was from oats and clover (10–18% and 13–18%, respectively). Under the direct effect of fertilizers, the yield of sugar beet roots increased by 20–30%. Under the after-effect, the best dose of fertilizers was N135P135K135 + 25 t/hectare of manure, and under the direct effect, it was N135P135K135 + 25 t/hectare of manure except for rotations II and VI, in which the dose was N45P45K45 + 50 t/hectare of manure. Barley and clover exhibited the most rapid after-effect (15 years), winter wheat the slowest one (40 years). The direct effect of fertilizers on sugar beet was the greatest after 45 years. When fertilizers were applied, crop rotation productivity improved by 11–25% between rotations I and IX, the greatest increase being with N135P135K135 + 25 t/hectare of manure. As compared to the control, productivity grew by 13–19% in rotation I and by 24–43% more in rotation IX. There was a significant shift in the agroclimatic conditions for cropping during the course of the experiment. Selyaninov’s hydrothermal coefficient shifted from dryland conditions to wet conditions. This was associated with an increase in temperature, humidity, and continentality. The latter was responsible for unstable crop yields. The data from our experiment provide a basis for modeling and understanding the effects of climate change on agricultural productivity.

Organic carbon (OC) accumulation in soil mitigates greenhouse gases emission and improves soil health. We aimed to quantify the dynamics of OC stock in soils and to justify technologies that allow annual increasing OC stock in the arable soil layer by 4‰. We based the study on a field experiment established in 1936 in the 9-field crop rotation with a fallow on Chernozem in European Russia. The RothC version 26.3 was used for the reproducing and forecasting OC dynamics. In all fertilizer applications at FYM background, there was a decrease in the OC stock with preferable loss of active OC, except the period 1964–1971 with 2–5‰ annual OC increase. The model estimated the annual C input necessary to maintain OC stock as 1900 kg·ha−1. For increasing OC stocks by 4‰ per year, one should raise input to 2400 kg·ha−1. The simulation was made for 2016–2090 using climate scenarios RCP4.5 and RCP8.5. Crop rotation without fallowing provided an initial increase of 3‰ and 6‰ of stocks in the RCP8.5 and RCP4.5 scenarios accordingly, followed by a loss in accumulated OC. Simulation demonstrates difficulties to increase OC concentration in Chernozems under intensive farming and potential capacity to rise OC stock through yield management.
