- •
We used Vis–NIR and fuzzy clustering to group observations in air dried soil cores.
- •
We used a digital gradient to establish boundaries between homogeneous zones.
- •
This methodology can be used in conjunction with other proximal sensing devices.
- •
Spectrally derived horizons were more homogeneous than traditional horizons.
