Regasolic soil and soil formation processes

Regasolic soil and soil formation processes

Hello, I was wondering what the dominant soil forming process in regasolic soil? Since it's diagnostic horizon is lack of a B horizon, I'm not sure how to know this dominant soil forming process since Maja explained in her most recent video that dominant soil forming processes are determined based off the lowercase letter in the diagnostic horizon. I was also wondering if we should know what areas regasolic soils are found? I couldn't find anything specific in the lab manual. Once last more general question: would accumulation of certain things in soil such as clay or Na+ be considered a translocation in terms of the 4 soil formation processes? Thank you!

There is NO dominant soil forming process in Regosols. These are soils at the very beginning of soil formation, and whatever soil forming processes do occur in them, they are just starting. Consequently, there is no B horizon in them and even if A or O or LFH horizons are present they are very thin; while C horizon is often labeled just as 'C' or with that modifier 'j' (eg Cgj).
Accumulation of clay or Na+ can be considered as examples of translocation soil forming processes, as long at they came to that horizon from another horizon.

Ok thank you! If accumulation of certain things don't come from a different horizon, would that instead be considered an example of addition soil forming processes?

Yes, that is correct
