Cambisols - Soils of NW-Thailand

In NW-Thailand, three different types of Cambisols were detected. The first type occurs on steep slopes and is derived mainly from Luvisols, Alisols and Acrisols by soil erosion. The second type is common on lower and concave slopes, depressions, and valleys controlled by colluvial deposits. The third type dominates the highest elevations with precipitation of more than 2000 mm a^-1 on low permeable rocks (mainly granite and gneiss).
