Both Loess Plateau and Northeast Phaeozem Region of China are main ecologically fragile regions in China. The unique climate conditions and intensified human activities may alter the soil organic carbon (SOC) content in these regions, and hence affect the carbon cycle of terrestrial ecosystem and climate change. In order to understand the mechanism of organic carbon transformation under those specific...
To study effects of different tillage on soil and water conservation (SWC) and soil carbon reduction on red-soil sloping land in south China, field experiments including three tillage measures(strip intercropping, contour intercropping and clean tillage) and a check were performed on the representative area named Jiangxi Eco-science Park of SWC. The surface runoff and soil loss of each treatment were...
Soils are a major reservoir of global carbon. Loss of agricultural soil carbon through erosion, management, and decomposition adds to the atmospheric loading of CO2. Soil erosion is a major driving force to help release the soil carbon to waterbodies and the atmosphere. The present study monitored transportation of SOC accompanying with soil erosion process at field runoff plots in the loess hilly...
Soil total organic carbon (TOC), light fraction organic carbon (LFOC), hot-water extractable carbon (HWC), cold- water extractable carbon (CWC) and microbial biomass carbon (MBC) were determined in eroded brown soils under three vegetation in a water and soil conservation monitoring station in northwest of Liaoning province. The results showed that the TOC-C content in young pine soil is 4.49 g kg...
