Regosolic soil order questions
Fragment of a discussion from Course talk:APBI200/Archive/2016-17WT2
Page 84 of the Lab Manual is really helpful for this. Basically you go through the steps in order, so this tells you which diagnostic horizons override the others. If it has a chernozemic Ah horizon but also has no B horizon, it's a chernozem rather than a regosol. A regosol can't have any of the other diagnostic horizons.
