Distribution of soil nutrients and erodibility factor under different soil types in an erosion region of Southeast China.

ABSTRACT:

Background

Soil erosion can affect the distribution of soil nutrients, which restricts soil productivity. However, it is still a challenge to understand the response of soil nutrients to erosion under different soil types.

Methods

The distribution of soil nutrients, including soil organic carbon (SOC), soil organic nitrogen (SON), and soil major elements (expressed as Al₂O₃, CaO, Fe₂O₃, K₂O, Na₂O, MgO, TiO₂, and SiO₂), were analyzed in the profiles from yellow soils, red soils, and lateritic red soils in an erosion region of Southeast China. Soil erodibility K factor calculated on the Erosion Productivity Impact Calculator (EPIC) model was used to indicate erosion risk of surface soils (0
