Geologic and not ...

October 18, 2012 07:36AM
Coming from a somewhat different pedological 'education' in central Europe, my view might be biased in a way that I possibly cannot contribute properly here, but we had many discussions on what Joe put as question 1 here, i.e. which are geologic processes and which are pedogenic, so I would like to comment on it.

The processes named in question 1 relate to mineral material that has been transported over a large distance, compared to the spatial variability of soils, and the major part of the transport process itself was not influenced by the soil on which the material has been deposited. This means they are not pedogenic processes, but geologic ones.

For question 2, the problem seems to me that surface sealing is not the same as restricted infiltration, but the latter a consequence of the former. Surface sealing as the process might be a pedogenic process, but infiltration is neither a pedogenic nor geologic process; and restricted infiltration is, strictly speaking, more or less the absence of a process at all. If there is no process going on - infiltration as water entering the soil - the consequence is the restriction or even absence of a special kind of pedogenesis (as far as this is caused by water [vertically] moving in the soil). However, most designations tell about the way how soils form, not how they do not form, and it seems reasonable to stick to this principle.

Are these processes pedogenic or geologic?
