An acrisol (AC) can be defined through :

an argic horizon, which has a cation exchange capacity (by 1 M NH₄OAc) of less than 24 cmol_c kg^-1 clay in some part, either starting within 100 cm from the soil surface, or within 200 cm from the soil surface if the argic horizon is overlain by loamy sand or coarser textures throughout

and :

a base saturation (by 1 M NH₄OAc) of less than 50 percent in the major part between 25 and 100 cm

For each RSG, there are some possible prefix and suffix qualifiers :
