Final Exam Questions

This is a Regosol since there is no B horizon.

Hi, Maja. For this 2008 final question, is that because the Cg horizon also has a j, which means the Cg horizon is not obvious, so it's not gleysol ? Or is there some other reasons? Thanks!

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
