Researchers studied forest soil organic carbon accumulation in the Dabie Mountains. They analyzed soil bulk density and organic carbon levels in the topsoil of the forest. The study found that soil organic carbon content was highest in the surface layer due to decaying vegetation. Organic carbon content varied with depth, increasing at low elevations and slightly at higher elevations. Overall, the forest soil in the region has a significant capacity for storing organic carbon, with an estimated density of 174.3 tons per hectare in the top 40 cm and 233.9 tons per hectare in the top 100 cm.
