- W2393897239 abstract "Reclaiming virgin land and plowing cropland destroy soil structure and accelerate the loss of soil organic carbon (SOC). Agricultural soil has been identified as one of sources of CO2 in the atmosphere and the potential of carbon sequestration from the atmosphere. Recent studies have indicated that agricultural soils are switching from carbon source to carbon sink of atmospheric CO2 through adopting the best management practices. However, quite often the SOC involved in redeposition in landscape is ignored when calculating the loss or sequestration of SOC. The purposes of this paper are to calculate the organic C stock of black soils in Northeast China and the amount of C having been released into the atmosphere since agricultural practices initiated in the region, and to evaluate the influence of soil erosion and deposition on SOC losses. The potential carbon sequestration of black soils is also estimated. The results showed that mean SOC density of black soils to 1 m depth in Northeast China is 12.54 kgC/m2,and the SOC stock is 646.2Tg C. The erosion losses of SOC in Heilongjiang and Jilin Provinces range 0.34～2.84 TgC/a,and the capacity of SOC redeposition in landscape is about 0.27～2.27 TgC/a. The erosion losses of SOC in Heilongjiang and Jilin Provinces range 0.34～2.84 TgC/a. The net historical release of CO2 from cultivated black soils to atmosphere is 34.6～434.6 TgC. The potential of carbon sequestration of black soils in Northeast China is 244.3 Tg C,with an average of 1.55 TgC/a over the next 20 years. " @default.
