a mesic or frigid STR; 85 % have an aquic or udic SMR; 92 % have a mixed
mineralogy; and no PSC is dominant in the Entisols (Table
5.3
). Ninety-three
percent of Inceptisol soil series in mollic subgroups have a mesic or frigid STR;
100 % have an aquic SMR; 93 % have a mixed mineralogy; and no PSC is dominant
in the Inceptisols.
