Amount of total organic carbon (a), nitrogen (b), and C : N ratio (c) in bulk soils of four agroecological zones (AEZs) under different land uses. Vertical bars represent standard error. Uppercase letters indicate significant differences () among land uses of the corresponding AEZ, and lowercase letters indicate significant differences between AEZs at corresponding land use.
