- •
We determined the factors governing soil erodibility using spectral reflectance.
- •
Soil organic matter (SOM), water-stable aggregates (WSA) and the geometric mean radius (Dg) control the soil erodibility.
- •
The quantitative wavelet analysis model predicted SOM, WSA >0.25 mm and Dg were significant.
- •
Soil erodibility was represented based on a spectral model of SOM, WSA >0.25 mm and Dg.
