13.6 Genesis of Cambic Horizons
The cambic horizon results from weak soil-forming processes, such as
argilluviation, podzolization, humification, etc.; this collection of processes can
be called “cambisolization.”
13.7 Summary
Cambic horizons are subsurface soil layers of pedogenic change without apprecia-
ble illuviated material. Cambic horizons occur in soil series of five orders, 26 sub-
orders, and 63 great groups (Table
13.2
). Soil series with cambic horizons are most
