very interesting question, but unfortunately, i don't know the answer.

Answer 2

Basalt soil and red soil, alum earth and alluvial soil

Answer 3

In fact, it depends on which part of VN you're talking about (deltas, mountains, costs...).

Well, for the red river basin contours, most of clays are now acrisol. But we also could find cambisol, regosol and leptosol.

In the past, leptosol was majority.

Hope could help you.
