Abstract

The paper analyzes the problems of carbon stocks variation in the pool of cropland mineral soils at the regional scale of the Russian Federation. The carbon stock balance of cropland soils was evaluated by estimating carbon gains and losses, and then the components of the carbon footprint were measured as a ratio of soil organic carbon balance to crop production quantity in terms of grain equivalent (t C/t grain eq.). The estimates for the period 2011–2020 have revealed that there is generally a small net gain of carbon on cropland in Russia, mainly due to the intake of carbon from plant residues. Most of the steppe region of Russia suffers from net losses of carbon at levels from –0.15 t C/t grain eq. up to –0.69 t C/t grain eq. In other regions, such as the Central Chernozem and Black Sea Coast regions, net carbon gain is observed in the range of 0.1–0.3 t C/t grain eq. due to the intake of significant biomass of crop and root residues as a consequence of intensive crop production.

评估俄罗斯地区耕地碳储量和碳足迹组成部分的平衡法

摘要本文分析了俄罗斯联邦区域范围内耕地矿质土壤碳储量的变化问题。通过估算碳损益对耕地土壤的碳储量平衡进行了评估，然后以土壤有机碳平衡与作物产量（吨碳/吨谷物当量）之比来衡量碳足迹的构成。对 2011-2020 年期间的估算表明，俄罗斯耕地的碳净增加量一般较小，这主要是由于从植物残留物中吸收了碳。在其他地区，如切尔诺泽姆中部地区和黑海沿岸地区，由于集约化作物生产带来的大量作物和根茎残留生物量，碳净增加量在 0.1-0.3 吨碳/吨谷物当量之间。
