Description
The Coloration Index (CI) was developed by Pouget et al. (1990) to characterize soil color properties in arid and semi-arid regions. Low CI values correlate with high concentrations of carbonates or sulfates, while higher values correlate with crusted soils and sands. The index helps monitor surface degradation and infiltrability variations.
