An cambisol (CM) can be defined through :
or :
- a mollic horizon overlying a subsoil which has a base saturation (by 1 M NH4OAc) of less than 50 percent in some part within 100 cm from the soil surface
or :
- one of the following diagnostic horizons within the specified depth from the soil surface :
Possible qualifiers
For each RSG, there are some possible prefix and suffix qualifiers :
