Organic carbon stock and stabilization in Lou soils with long term addition of manures on Loess Plateau

摘要：

Chinas farmers have a very long history of using manures in their fields. Owing to the long-term addition of manures, an anthropogenic layer was formed on the top of original soil profile (drab soil) in Guanzhong Plains on the Loess Plateau. This soil is named the Manural Loessial soil (or Lou soil, Lou means the different stories of a building in Chinese). The depth of anthropogenic layer is in range of about 30 to 100 cm depth, which has a close relationship with the productivity of the soil. This fertile agricultural soil has sustained the agriculture in the region for millenniums. However, there is less information available on the stock and stabilization of organic carbon in this unique soil.
