Abstract
The land use system in Russia changed considerably after 1990: 30.2 million ha of croplands were abandoned. Based on the own field investigations that were carried out in abandoned lands of different age (Luvic Phaeozems, deciduous forest zone; Moscow region, 54 deg 50' N, 37 deg 37' E), it has been shown that after 4.5 yr of abandonment, the former croplands acted as a stable sink of CO{sub 2}. The net ecosystem production (NEP) in the post-agrogenic ecosystems averaged 245 +- 73gCm-2 yr-1 for the first 15 yr after land use change that corresponds to an estimated 74 +- 22 Tg C yr-1 for the total area of abandoned lands in Russian Federation. Currently, the Russian territory acts as an absolute sink of atmospheric CO{sub 2} at a rate about 0.90 Pg C yr-1. Using three different approaches, it was demonstrated that after 1990, the carbon sequestration in Russian soils (0.20 cm layer) has averaged 34 +- 2.2 Tg C yr-1. This soil C forms net biome production (NBP) where carbon lifetime is much longer than in 'Kyoto forests'. Thus, the post-agrogenic ecosystems in Russia provide with the additional CO{sub 2} sink in NEP and NBP that could annually compensate
