you are correct, this is a Regosol since glaying soil formation process is only at its beginning, as indicated by "gj" in the Cgj
So when there are both regosolic and chernozem diagnose (e.g., has an Ap of more than 10cm, and doesn't has a B horizon) I should still recognize it as chernozem ?
I am not sure that I understand your question..... Ap is not a diagnostic horizon for any of the 10 soil orders
Soil without B horizon is Regosol
